Any Volvo mechanics out there?

[ross1]

Plea for help obtaining a service bulletin, specifically # 2 23 0056 regarding emissions readiness check "issues".
Needing the proper "modified trip" drive cycle prescribed in that doc.
There is a consumer brochure which I've seen which prescribes a simple(albeit inconvenient if not impossible and certainly time consuming) yet ineffective procedure. Of course with the oblique disclaimer that this "does not guarantee the readiness".
I have a ton of time in trying to prepare this POS for emission testing and ready to kill or cry.

You could try in the off topic section. At least one guy there that is (or used to be) a Volvo mechanic (83BMW733iyoder), but possibly more.
Threads do derail pretty quickly, but there’s often helpful stuff in between

Jeez, Ross, you know you're going to have to describe the car a bit more specifically than "POS", for me to try to look up service bulletins for it, don't you? I have Alldata, even at home...I'll be glad to see what I can find, but I can't look up SIBs by the number, sorry

Googled it:

Volvo Technical Service Bulletin #SB 2-23-0056

Start with the vehicle cool, below 122 degrees F.
Turn off the air conditioning.
Select a location where the driving can be done without violating traffic laws and you can stop safely at the side of the road.

1. Start the engine and accelerate to approximately 1500-2000 rpm.
2. Drive for 6 minutes at 1500-2000 rpm.
3. Stop the vehicle and remain at idle in drive for 70 seconds.
4. Accelerate to at least 45mph and drive for 5 minutes at 1800-2200 rpm.
5. Stop the vehicle and remain at idle in drive for 60 seconds.
6. Accelerate to at least 45 mph and drive for 4 minutes at 1800-2200 rpm.
7. Stop the vehicle and remain at idle in drive for 60 seconds.
8. Park the vehicle and turn off the engine.

This procedure must be performed TWICE from a cold start to set the readiness codes.

Just lovely
Thank you sir, is the entire SB out there?. Do you remember if the term "modified trip" was used? Seems it was a problem for them(now me)and the DC sequence was revised.

Supposedly several states have waived the monitor readiness for these, mine is not one of them. After 4 days of mixed driving 5, FIVE! remain not ready.

It is all but impossible to drive for 20 minutes at any speed around here without stopping. Perhaps highway but she'll be well warmed by the time I get to one and driving @50 is likely to get me run over or shot.

I'm tempted to ship it as is and let this lutefisk eating POS, err '98 V70XC with B5254T engine and w/o SR (no strontium, who knew?) ready itself at it's own leisure.

Section:
2

Group:
23

No.:
0059

Year:
02

Month:
07

Reference:

This Service Bulletin replaces the previous SB 23-0059 dated January 2002 and supersedes TNN 28-40 dated December 2001, which both should be discarded.

Purpose:

Revised repair verification driving cycle, Service Manual TP 2308202 M4.4 and TP 2301202 M4.3

Affected vehicles:
Vehicles equipped with Motronic 4.4 or Motronic 4.3 Engine Management System

OBD II Readiness Codes: Revised Reset Instructions

Background:

The MY 1996,1997 and 1998 Volvo 850/S70/V70/C70s require an extended driving period in order to reset readiness codes from INCOMPLETE to COMPLETE. When verifying an emission related repair, the TRIP identified in Section KKKK of the Engine Management System Service Manual TP 2308202 M 4.4 or Section EBU of the Engine Management System Service Manual TP 2301202 M 4.3 may not allow all of the diagnostic monitors to run.

The following instructions, which supersede TRIP instructions contained in the above referenced service manual, will exercise all of the diagnostic monitors on these models. As long as no diagnostic trouble codes have been stored, the readiness codes will be set to COMPLETE upon completion of two consecutive trips driven according to the instructions.

OBD II Readiness Codes: Revised Reset Instructions

Introduction 1

This on-road driving sequence will allow all of the diagnostic functions an opportunity to run. After two correct, consecutive TRIPS, the readiness codes should be set to COMPLETE, provided no diagnostic trouble codes have been stored.

General Instructions 2

No Diagnostic Trouble Codes (DTC) present in system.

Connect Volvo Systems Tester (VST). Enter the DIAGNOSTIC CHECK menu to verify if a trip has been completed refer to VST Screen Navigation for OBD II Trip and Flywheel Readiness.

M 4.4

Flywheel adaptation must be completed (status READY) TIP: Look in the Monitor Test Scroll List and find the entry "F ADAP." It will say either READY or NOT READY. If it says READY, continue. If it says NOT READY refer to setting the flywheel adaptive values to ready.

M 4.3

NOTE:
The VST can not read the flywheel adaptation on M 4.3 vehicles. Therefore we must assume that they are not set. See Setting the flywheel adaptive values to ready to assure flywheel adaptive is set.

M 4.3

When interrogated using a generic OBD II scan tool, the MY 1996 Volvo 850, equipped with Bosch Motronic 4.3 Engine Management System, may experience all of the Readiness Codes changing from COMPLETE to INCOMPLETE when the ignition key is cycled. This behavior applies to all 1996 M 4.3 850s and cannot be corrected. DO NOT turn the engine off until after the Enhanced Inspection/Maintenance OBD II check has been completed.

In order to insure EVAP leakage detection completion, the fuel level in the car should be above 1/4 and below 3/4 tank.

Air conditioning (A/C) must be off during idle periods. A/C compressor activation during the Evap diagnostic may Interrupt the Evap test.

Select a suitable route where it is possible to safely stop at the side of the road. Obey all traffic regulations and posted speed limits.

Engine temperature at start must be between +29°C (84°F) +49°C (122°F). If engine temperature is below +29°C, start engine to warm up over +29°C and then shut off. Restart engine when coolant temperature is between +29°C-+49°C. TIP: The coolant temperature can be read out from the SCROLL LIST using the Volvo Systems Tester (VST).

Another confirmation that the ECU has seen the correct start criteria is to access the EFI code 112 in the DIAGNOSTIC CHECK menu. With ignition key in position 2, engine off, access the DIAGNOSTIC CHECK menu and press enter. The EFI codes will appear. Scroll down until you get to EFI 112.

Start engine, go directly from position 2 to position 3 do not cycle key. The EFI 112 status should then change from NOT TESTED to TESTED. This indicates that the ECU has seen the correct start criteria.

Trip Instructions 3

Start Engine

^ Accelerate gently to 1500 - 2000 rpm, manual gear box equipped, gear selection dependent on highway

^ Drive for 6 minutes at 1500 - 2000 rpm

^ Safely stop the car and idle engine for 70 seconds

[Fuel Trim adaptive functions are checked by the above steps.)

^ Accelerate gently to 1600 - 2000 rpm

^ Drive for 6 minutes at 1600 - 2000 rpm, manual gear box equipped, gear selection dependent on highway

^ Stop the car and idle engine for 70 seconds

[Secondary Air diagnosis should be carried out at this time (if equipped).]

^ Accelerate gently to at least 45 mph, drive for 5 minutes at 1800 - 2200 rpm, manual gear box equipped, gear selection dependent on highway

^ Top the car and idle engine for 60 seconds

[EVAP Leakage diagnosis should be carried out at this time]

^ Accelerate gently to at least 45 mph, drive for 4 minutes at 1800 - 2200 rpm, manual gear box equipped, gear selection dependent on highway

^ Stop the car and idle engine for 60 seconds

^ Accelerate gently to 1800 - 2200 mm

NOTE:
Repeat this last step 3-4 times. To set the cycle flag for idle air adaptation diagnosis the engine needs to come to idle 7 times. Under normal driving conditions you come idle 7 times very easily, but during the forced "TRIP" there are just 3 idle phases

^ STOP, DO NOT SHUT OFF ENGINE, trip completed move gear selector to neutral apply parking brake

^ Check that all diagnostic functions are completed, using Volvo Systems Tester (see below)

^ The diagnostic check will now say, "TRIP COMPLETED".

^ M 4.4 systems will also display either READINESS = YES or NO based on completion of 2 "TRIPS". M 4.3 systems will not display the READINESS code, but 2 complete "TRIPS" will set the READINESS code.

^ If all diagnostic functions are NOT completed there are ways to rerun portions of the trip, see the descriptions following.

^ STOP, DO NOT SHUT OFF ENGINE, trip completed move gear selector to neutral apply parking brake

^ Check that all diagnostic functions are completed, using Volvo Systems Tester (see below)

^ The diagnostic check will now say, "TRIP COMPLETED".

^ M 4.4 systems will also display either READINESS YES or NO based on completion of 2 "TRIPS". M 4.3 systems will not display the READINESS code, but 2 complete "TRIPS will set the READINESS code.

^ If all diagnostic functions are NOT completed there are ways to rerun portions of the trip, see the descriptions following.

Using the Volvo Systems tester, VST, you can determine if all diagnostic functions were completed. If any one or more were not tested you can rerun only that portion of the TRIP. To determine which diagnostic functions have not been completed, using the VST enter the DIAGNOSTIC CHECK menu. At the TRIP/READINESS window press enter. Here the EFI codes representing individual diagnostic functions will be displayed. Note the ones that are NOT TESTED. Below are the specifics on how you can address individual codes:

NOTE:
The VST does not continuously provide "online" updates. If you want to check the status of readiness before, during or after a drive cycle you must always exit the VST Diagnostic Test and re-enter.

EFI 233, Adaptive Idle Air trim. After completing the trip and seeing that this function is not set, idle the Engine for 60 seconds, press the accelerator and rev up the Engine above 1500 rpm for a few seconds, return to Idle for 60 seconds. Continue this until EFI 233 is completed.

EFI 425/436, Rear oxygen sensor, Accelerate to at least 45 mph, drive for 5 minutes at 1800 - 2200 rpm.

EFI 435, Front heated oxygen sensor, slow response. Drive the car with an Engine speed between approximately 2200 to 2800 rpm and a load between 1,1 to 1,8 ms (LOAD - TL).

Automatic gearbox equipped, use low gear it necessary.

^ drive for 2 minutes at 1800 - 2200 rpm, manual gear box equipped gear selection dependent on highway

^ accelerate directly to 3000-3500 rpm for 30 seconds, manual gear box equipped in third gear

^ reduce rpm to 1800 - 2200 for 2 minutes, manual gear box equipped in fifth gear

^ accelerate directly to 3000 - 3500 rpm for 30 seconds, manual gear box equipped in third gear

^ reduce rpm to 2300 - 2500 for 2 minutes, manual gear box equipped in forth gear

EFI 611/612, Fuel tank system. Run the quick test in VST for Leakage detection monitoring. (ACTIVATION->ACTIVATE DIAG->LEAKAGE DIAGNOSIS

EFI 442+445448,Pulsed Secondary Air Injection system, Run the Quick test in VST for the Pulsed Secondary Air system monitoring (ACTIVATION->ACTIVATE DIAG->SAS DIAGNOSIS)

Again: Please note that although the readiness codes may present as INCOMPLETE, this condition will not inhibit the OBD II system from monitoring, detecting, and subsequently storing a corresponding DTC in system memory.

Thanks Chris!
Yeah, that's what I wanted. Do you believe all that
Of note is that in an EPA document I discovered which lists various vehicles which are troublesome to test there are no BMWs.

Equally absurd is that the job pays 1.5 hrs

I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech.I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech. I am not a Volvo tech.

Honestly, though, if you'd been around for the last week watching the computer issues I've had with BMW's, you'd wonder why anyone would do this for a living......

All that for a Volvo, bad deal lol
