Condition

Some customers may comment on a Replace Brake Pad or Service Brake Pad Life
System message displayed at very low mileage.

Cause

The cause of the condition may be a calibration in the brake pad life monitoring system
that reduces the calculated pad life too quickly.

Correction

Reprogram the Brake System Control Module (BSCM) with the latest calibrations and
reset the brake life monitor system. If the vehicle has more than 10,000 km (6,250 mi),
replace the brake pads.

Service Procedure

Warranty Information

Note: Stable battery voltage is critical during
programming. Any fluctuation, spiking, over voltage or
loss of voltage will interrupt programming. Install a GM
Authorized Programming Support Tool to maintain
system voltage. Refer to for further information. If not
available, connect a fully charged 12 V jumper or
booster pack disconnected from the AC voltage supply.
DO NOT connect a battery charger.

For vehicles repaired under warranty, use:

If reprogramming the BSCM, refer to K160 Electronic
Brake Control Module: Programming and Setup in SI.
To reset the brake life monitor system, refer to Brake
Pad Life Monitoring Reset in SI.

*To avoid warranty transaction rejections, carefully read and
follow the instructions below:
• The SPS Warranty Claim Code must be accurately
entered in the “SPS Warranty Claim Code” field of the
transaction.
• When more than one Warranty Claim Code is generated
for a programming event, it is required to document all
Warranty Claim Codes in the “Correction” field on the job
card. Dealers must also enter one of the codes in the
“SPS Warranty Claim Code” field of the transaction,
otherwise the transaction will reject. It is best practice to
enter the FINAL code provided by SPS.

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.
