With regard to any of the DTC's related to the Electronic Brake Control Module (EBCM), the list does not adequately explain the differences.
In post 2000 models DTCs C1261 thru C1274 are set when there is a malfunction in the solenoid circuit internal to the EBCM and there are no tests that can be made with the EBCM installed on the car.
On 1997 thru 2000 models the service manual gives specific testing steps to determine cause and possible corrective action.

Suffice it to say that when dealing with the EBCM, the merged DTC code list is not very accurate in showing differences.

 

Thank you so much. Great information and effort on your part

 

Thanks for taking the time to do this. I have printed a copy and I am sure it will be very helpful to me in the future taking care of my 2002 corvette C5.

 

I've read a lot and have your code post bookmarked but don't see: 10 PCM 2 codes listed. I reset them thinking a glitch but want to know if there is more to this.

Thanks,
Joel

I believe that this is the most up to date TSB:

Vehicle: All Technical Service Bulletins

VSES - Warning Displayed, DTC C1288 Stored

This bulletin is being revised to add an additional model year and revise the text. Please discard Corporate Bulletin Number 01-05-25-004 (Section - 05 Brakes).

Condition

Some customers may comment that the "Yellow" message, "Service Traction Active Handling", is illuminated on the Driver Information Center. The technician may find chassis DTC C1288 - Vehicle Stability Enhancement System (VSES) Steering Wheel Sensor Phase A and B. When this code is set, the VSES is turned off, ABS and TCS remain operational.

Correction

Verify the Techline equipment has been updated with TIS software 12 or newer. If it has not been updated, do so now. This software was broadcast to dealerships on 11 /13/01. Disc Number 12 will be mailed November 14,2001.

1. Install the scan tool to the vehicle.
2. Enter the chassis applications.
3. Select F1: ABS/TCS/VSES.
4. Select F4: ID Information.
5. Select Fl: Controller Information 2.

5.1. If the DE Calibration P/N is not 12220685, it will be necessary to update the ABS module.

5.2. If the calibration is already 12220605, refer to the Service Manual, Brakes, Antilock Brake System, Diagnostic Information and Procedures, DTC 1288, SI2000 Document ID 670707.

Important:
The update cannot be performed until fuse # 25 (Body Control Module-Ignition 1, Instrument Panel Control) 10 amp is removed from the instrument panel fuse block which is located on the passenger side of the vehicle (under the instrument panel and under the toe board).

Without removal of the fuse (prior to requesting information), unsuccessful reprogramming may occur.

6. Power down the scan tool.
7. Turn OFF the ignition and remove the key.
8. Remove fuse # 25, (Body Control Module-Ignition 1, Instrument Panel Control) 10 amp.
9. Using the scan tool, perform the usual SPS reprogramming of the ABS module.
10. Power down the scan tool.
11. Turn OFF the ignition and remove the key.
12. Replace fuse # 25, (Body Control Module-Ignition 1, Instrument Panel Control) 10 amp.
13. Verify the ABS DE Calibration P/N. If it is not P/N 12220685, redo the SPS programing procedure listed above.
