CONDITION:
Some 1991 Cutlass Calais and 1992 Achieva models may exhibit 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.
CORRECTION:
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 1991 Cutlass Calais and in 1992 Achieva, and 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/O Harco Industries at 513-836-8916 or mailed to:
Harco Industries, Attention Bob Early

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 allowed 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 cadridge or diagnosis for the ABS VI brake system, please contact Delco Chassis
