Code 1288
Was told that I have a Code 1288 and need to take the car to a dealer for a reporgram per service bulletin 01-05-25-004a. Would appreciate some information on this service bulleting if anyone has it.
My problem is the "Service Active Handling" light comes on "unpredictably".
Thanks in advance. Gib :chevy

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.

Select F1: ABS/TCS/VSES.
Select F4: ID Information.

If the DE Calibration P/N is not 12220685, it will be necessary to update the ABS module.
If the calibration is already 12220685, 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.
Power down the scan tool.
Turn OFF the ignition and remove the key.
Remove fuse #25, (Body Control Module-Ignition 1, Instrument Panel Control) 10 amp.
Using the scan tool, perform the usual SPS reprogramming of the ABS module.

Clear the codes from all the modules.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
