DTC 82

82 CALIBRATION MALFUNCTION

DTC 82 Calibration Malfunction:

DTC 82 Calibration Malfunction:

Circuit Description:
This DTC allows the 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 as a security measure to prevent improper use of calibrations or changes to these calibrations that may alter the designed function of ABS.

DTC Will Set When:
DTC 82 can be set at key up. If the program identifier is incorrect or the memory checksum is incorrect, a malfunction exists.

Action Taken:
A malfunction DTC is stored, ABS is disabled and the amber ABS warning lamp is turned "ON."

DTC Chart Test Description:
Number(s) below refer to circled number(s) on the diagnostic chart.
1. Checks to see if the malfunction is present during diagnosis. If present, the EBCM is not functioning correctly and must be replaced.

Important
^ At the time of printing, 1996 vehicles of ABS VI were not being field reprogrammed to correct this failure. A service bulletin will be issued when EEPROM reprogramming is authorized.

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 EBCM.

The frequency of the malfunction can be checked by using the enhanced diagnostic function of the Tech 1.
