DTC 82

Fig. 680 Code 82: Calibration Fault.:

DTC 82 Calibration Malfunction:

Circuit Description:

This DTC allows the EBCM/EBTCM to check for a calibration failure by comparing the calibration value to a known value stored in the EBCM/EBTCM's memory.

This test 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. A malfunction exists if the EBCM/EBTCM internal memory calibration is incorrect.

Action Taken:

A malfunction DTC is stored, ABS is disabled and the "ABS" indicator lamp is turned "ON."

DTC Chart Test Description:

Number(s) below refer to circled number(s) on the diagnostic chart.
1. This step checks to see if the malfunction is present during diagnosis. If present, the EBCM/EBTCM is not functioning correctly and must be replaced.

Diagnostic Aids:

An intermittent DTC 82 is most likely caused by a faulty EBCM/EBTCM that is sensitive to temperature changes. If DTC 82 occurred more than once, but is intermittent, replace EBCM/EBTCM.

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