Test H: Abs Warning Indicator Is Inoperative
- Turn ignition switch to LOCK position. Connect NGS tester (418-F052). Select instrument cluster active command ALL LAMPS ON and OFF. If ABS warning indicator illuminates and turns off, go to next step. If ABS warning indicator illuminates and remains on, go to step 3.
- Turn ignition switch to LOCK position. Disconnect instrument cluster connector C809. See Figure and ABS module connector C385. See Fig 1. Measure resistance between ground and terminal No. 16 (Black/Red wire) at harness side of connector C385. If resistance is more than 10 k/ohms, see appropriate ANTI-LOCK article in BRAKES. If resistance is less than 10 k/ohms, repair short in Black/Red wire and retest.
- Turn ignition switch to LOCK position. Check for corrosion, pushed out pins and connectors that are not connected properly. Repair any damage found and reconnect any loose connectors. Operate system. If problem still exists, replace instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Configure replacement instrument cluster, see appropriate MODULE COMMUNICATIONS NETWORK article. If problem does not exist, then system is operating properly at this time, clear any DTCs and retest.
