Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT WIRING HARNESS BETWEEN ABS /TCS HU/CM AND DLC-2 FOR CONTINUITY AND SHORTS • Turn ignition key to OFF. • Connect WDS or equivalent to DLC-2. • Turn ignition key to ON (engine OFF). • Perform DTC inspection.
• Is error message displayed regarding communication between ABS/TCS HU/CM and WDS or equivalent?
Yes
If a communication error message is displayed even after inspecting according to procedures displayed on the WDS or equivalent, go to Step 4.
No | Go to next step.
2 | CHECK FOR DTCs IN PCM • Is DTC for engine control system obtained? (See DTC TABLE [L3]) | Yes | Follow inspection procedures for engine control system.
No | Go to next step.
3 | INSPECT RPM SIGNAL IN ABS/TCS HU/CM • Inspect the following item using WDS or equivalent .

  - RPM (Engine speed)

• Turn ignition key to ON (start engine)
• Is engine speed 400-1500 rpm?
Yes
Go to Step 5.
No | Go to next step.
4 | INSPECT WIRING HARNESS BETWEEN ABS/TCS HU/CM AND PCM FOR CONTINUITY • Turn ignition key to OFF. • Disconnect ABS/TCS HU/CM and PCM connectors. • Connect SST (adapter harness) to ABS/TCS HU/CM connector (harness side). • Measure continuity between terminal S of SST (adapter harness) and terminal 2N of PCM connector (harness side).
• Is there continuity?
Yes
Replace PCM then go to next step.
No | Repair or replace harness between ABS/TCS HU/CM and PCM then go to next step.
5 | VERIFY CURRENT STATUS OF MALFUNCTION • Clear DTC from memory. (See Clearing DTCs Procedure) • Start engine and drive vehicle at 10 km/h {6.2 mph} or above. • Gradually slow down and stop vehicle.
• Is the same DTC present?
Yes
Replace ABS/TCS HU/CM, then go to next step.
No | Go to next step.
6 | VERIFY AFTER REPAIR PROCEDURE • Is there any DTC present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
