CIRCUIT DESCRIPTION
The Electronic Brake Control Module (EBCM) controls the ABS indicator lamp illumination by supplying a ground to the EBCM 10-way terminal B. When the vehicle is started or the ignition is turned to the RUN position, the ABS indicator should illuminate for three seconds and turn off.

DIAGNOSTIC AIDS
If the ABS indicator lamp is off constantly with no DTCs set, an open circuit is present between the instrument panel cluster and the Electronic Brake Control Module (EBCM), the GAUGES fuse is open or an open is present between the Fuse Block and the Instrument Panel Cluster.

TEST DESCRIPTION
The numbers below refer to the steps in the diagnostic table:
2. This step manually (with fused jumper) turns on the ABS indicator lamp.
5. This step checks for a short to ground in CKT 39.
7. This step checks for an open in CKT 867.
8. This step checks for ignition voltage at the instrument cluster.
