Circuit Description

DTC 11 checks state of ABS warning light circuit to identify a situation in which driver could not be alerted to a system malfunction. Due to an integral Lamp Driver Module (LDM) within IP cluster, EBCM/EBTCM must provide a ground to turn ANTI-LOCK indicator off.

DTC will set when indicator light circuit is open or shorted to ground/battery. This malfunction prevents EBCM/EBTCM from controlling ANTI-LOCK indicator light. A malfunction code is stored but ABS remains functional.

NOTE: Test numbers refer to numbers on diagnostic chart. To identify circuits and terminals referenced in text and flowcharts, see WIRING DIAGRAMS  .
