ANTILOCK BRAKE SYSTEM (ABS)/BRAKE WARNING INDICATOR LAMP ON (REPROGRAM EBCM)
Models Affected:
1992 SUNBIRD AND GRAND AM MODELS AND 1991 GRAND AM MODELS
CONDITION:
Some 1992 Sunbird and Grand Am and 1991 Grand Am models car owners may experience an Antilock Brake System (ABS) indicator lamp or brake
warning lamp coming on prematurely. This may result in any combination of ABS codes 38 and/or 41 and 86 being set.
CONDITION:
Reprogram EBCM using Tech 1 and cartridge.
Delco Chassis has released a reprogramming cartridge for servicing vehicles with any combination of ABS brake codes 38 and/or 41 and 86. This
cartridge, which currently is to be used to reprogram the EBCM in 1992 Sunbird and Grand Am and in 1991 Grand Am models is available only through
Delco Chassis Technical Assistance at 1-800-523-0203. Later in the 1993 model year the reprogramming function will be added to the mass storage
cartridge through a CD software release. The following criteria must be met before reprogramming the EBCM:
-
Any combination of codes 38 and/or 41 and 86 must be present.
-
Only vehicles with verified codes 38 and/or 41 and 86 can be reprogrammed.
-
The work order, with the VIN clearly marked must be faxed to
Robert Early, C/0 Harco Industries at 513-836-8916 or mailed to:
Harco Industries, Attention Bob Early
905 South Main Street
Englewood, OH 4532
This information will be used by Delco Chassis to develop a technical assistance case.
Prior to reprogramming, if any codes other than 38 and/or 41 and 86 are present, proceed to the vehicle's service manual SECTION 5E1 for diagnosis of
those codes first.
After reprogramming, clear codes using the 1988 - 1993 Chassis selection of the Tech 1 Mass Storage Cartridge.
WITH FOOT OFF BRAKE PEDAL, start the engine twice and allow it to run for at least 10 seconds each time. If any codes return (including 38 and/or
41 and 86), proceed to the vehicle's service manual SECTION 5E1 for further diagnosis.
If there are any questions regarding the usage of this reprogramming cartridge or diagnosis for the ABS VI brake system, please contact Delco Chassis
technical assistance at the telephone numbers listed above.
