STEP 3. Check the wiring harness between the WCM connector C-09 (terminal No.4) and the ground for open circuit.
(1) Disconnect the connector and measure the resistance at the wiring harness side.
(2) Turn the ignition switch to the ON position.
(3) Measure the resistance between terminal No.4 and the ground.OK: Continuity exists (2 Ω or less)
note | Also check grounding connector C-01, joint connector (4) C-108 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If grounding connector C-01, joint connector (4) C-108 is damaged, repair or replace the damaged component(s) as described in GROUP 00E, Harness Connector Inspection . |
Is the wiring harness between WCM connector C-09 and the ground in good condition?
Go to Step 4. Repair the wiring harness between WCM connector C-09 (terminal No.4) and ground.
