DTC 82

INSPECTION PROCEDURE

CIRCUIT DESCRIPTION:
This DTC allows the Electronic Brake Control Module (EBCM) to check for a calibration malfunction by comparing the calibration value to a known value stored in the EEPROM. This DTC is also used a security measure to prevent improper use of calibrations or changes to these calibrations that may alter the designed function of Antilock Brake System (ABS).

FAILURE CONDITION:
DTC 82 can be set at key-up. If the program identifier is incorrect or the memory checksum is incorrect, a malfunction exists.

DIAGNOSTIC AIDS:
An intermittent DTC 82 may be caused by a bad cell in the EEPROM that is sensitive to temperature changes. If DTC 82 failed more than once, but is intermittent, replace the EBCM.
The frequency of the malfunction can be checked by using the enhanced diagnostic function of the TECH-1 as described in "TECH-1 Diagnostics".
