C1282

CIRCUIT DESCRIPTION
This DTC allows the EBCM to check for a calibration failure by comparing the calibration value to a known value stored in the EBCM'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.

CONDITIONS FOR SETTING THE DTC
DTC C1282 can be set at ABS initialization. A malfunction exists if the EBCM internal memory calibration is incorrect.

ACTION TAKEN WHEN THE DTC SETS
A malfunction DTC is stored, ABS is disabled, and the ABS indicator lamp is turned ON.

CONDITIONS FOR CLEARING THE DTC
Conditions for the malfunction are no longer present and the scan tool CLEAR DTCs function is used. One hundred ignition switch key cycles have passed with no malfunctions detected.

DIAGNOSTIC AIDS
An intermittent DTC C1282 is most likely caused by a malfunctioning EBCM that is sensitive to temperature changes. If DTC C1282 occurred more than once, but is intermittent, replace EBCM.

The frequency of the malfunction can be checked by using the ENHANCED DIAGNOSTIC function of the scan tool.
