C0073

Kelsey-Hayes Electronic Brake Control Module:

CIRCUIT DESCRIPTION
The Electronic Brake Control Module (EBCM) initializes a self-test when the ignition is turned to the "RUN" position. The EBCM self-test verifies all internal circuitry within the EBCM is operating correctly.

CONDITIONS FOR SETTING DTCs
^ Any condition within the EBCM which causes a memory error.

ACTION TAKEN WHEN THE DTC SETS
^ ANTILOCK indicator lamp is illuminated
^ ABS is disabled

NOTE: Diagnostic Trouble Code (DTC)s C0071 through C0074 are permanent latched DTCs, which indicates the above is true until the DTC is cleared using a Scan Tool.

CONDITIONS FOR CLEARING THE DTC
^ Conditions for setting the DTC are repaired and the Scan Tool clear (DTCs) function is used.

DIAGNOSTIC AIDS
DTCs C0071 through C0074 are EBCM internal diagnosis. The EBCM must be replaced if these tests show the EBCM circuitry has failed.

DTC C0071, C0072, C0073, C0074 EBCM Internal Fault:

TEST DESCRIPTION
The numbers below refer to the step numbers on the chart.
