DON'T DO THIS

Reprogram the EBCM with TIS version 7.5 Released July 26,2004 or newer.
DO NOT replace the EBCM.


Condition
Some customers may comment that the ABS light, Service Brake System message comes on intermittently during initial start-up. The condition does not cause a DTC to be stored permanently.

Cause
The cause may be a timing issue related to the cranking/starting of the vehicles. It appears that the condition is more likely to occur on vehicles with diesel engines, though it can occur on vehicles with gasoline engines as well.

Correction
Reprogram the EBCM with TIS software version 7.5, released July 26,2004 or newer. Refer to Service Programming System (SPS) (SI Document ID #1451930).
