SYMPTOM TROUBLESHOOTING 04–03–11 04–03 End Of Sie 5 CONFIRM THAT MALFUNCTION SYMPTOM • Do ABS warning light go out after more than Yes Temporary poor connection at terminal. No Go to next step. 6 CHECK FOR OPEN CIRCUITS IN ABS HU/CM • Disconnect ABS HU/CM. Connect the SST • Use the SST connector to ground ABS Yes Replace ABS HU/CM (open circuit in ABS HU/CM). No Go to next step. *7 CHECK TO SEE WHETHER MALFUNCTION • Disconnect instrument cluster. • Is there continuity between following SST Yes Replace instrument cluster (open circuit or ground to short No Repair wiring harness between ABS HU/CM (terminal W) 8 INSPECT ABS HU/CM IGINITION POWER • Check the voltage for PID/DATA monitor • Is voltage within specification? Yes Replace ABS HU/CM (open circuit or short in ground circuit No Go to next step. 9 INSPECT BATTERY • Is battery voltage normal? Yes Go to next step No Inspect battery and charging system 10 INSPECT CHARGING SYSTEM • Is battery voltage normal with electrical load Yes Go to next step No Inspect charging system (drive belt tension, generator, etc). *11 INSPECT WIRING HARNESS BETWEEN ABS • Disconnect ABS HU/CM. Connect SST (49 • Is voltage approximately 12V at SST Yes Go to next step. No Repair wiring harness between fuse block and ABS HU/CM *12 INSPECT WIRING HARNESS BETWEEN ABS • Turn ignition switch to LOCK • Is there continuity between SST connector Yes If a communication error message is displayed on WDS or No Repair wiring harness between ABS HU/CM and ground. *13 INSPECT WIRING HARNESS BETWEEN ABS • Disconnect ABS HU/CM.
