Supercede:
This bulletin is being revised to add a build date to Cause/Correction #1. Please discard Corporate Bulletin Number 09-06-03-002F (Section 06 -
Engine/Propulsion System).
This bulletin provides information on one condition with two different causes/corrections. The following repairs are vehicle specific. Please review the
bulletin in it's entirely before performing the fix.
Condition
Some customers may comment that the vehicle will not crank or start and the battery goes dead.
Cause #1 (2009-2010 Acadia, Enclave and OUTLOOK Models Only Built Prior to April 1, 2010)
The ECM runs an emission test after the vehicle has been driven for more than 8 km (5 mi). During the test, the IPC may stay awake and draw parasitic
current. If the customer's driving profile consists of driving short distances between 8-16 km (5-10 mi) at a time without longer drive cycles to bring the
battery back to full state of charge, the battery may become discharged enough to not allow the vehicle to crank or start.
Correction #1 (2009-2010 Acadia, Enclave and OUTLOOK Models Only Built Prior to April 1, 2010)
Important
This calibration should only be used after all battery/electrical system troubleshooting has yielded no root cause for the no start condition and
the customers driving habits match those described above.
A revised calibration has been developed to address this condition. Technicians are to reprogram the IPC with the latest calibrations available. This new
service calibration is available on TIS2WEB using the Service Programming System (SPS). Refer to the SPS procedures in SI.
When using a Tech 2(R) or a multiple diagnostic interface (MDI) for reprogramming, ensure that it is updated with the latest software version.
During programming, the battery voltage must be maintained within the proper range of 12-15 volts. Only use the approved Midtronics(R) PSC 550
Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
Warranty Information #1
For vehicles repaired under warranty, use:
Cause #2 (All Models Equipped with RPO KA1 and Minus RPO A45)
This condition may be caused by the heated seat module discharging the battery. The module keeps the serial data bus active, which creates a
cumulative, continuous amperage draw on the battery after the vehicle is shut down, until the state of charge reaches three volts.
Correction #2 (All Models Equipped with RPO KA1 and Minus RPO A45)
