Inspection Procedure
- CHECK WIRE HARNESS (COWL SIDE J/B RH - POWER SOURCE CONTROL ECU AND BODY GROUND)
- Disconnect the RD J/B connector.
- Disconnect the J55 ECU connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance
COWL SIDE J/B RH - POWER SOURCE CONTROL ECU AND BODY GROUNDTester Connection (Symbols) Specified Condition RD-2 - J55-11 (ACCD) Below 1 ohms RD-2 or J55-11 (ACCD) - Body ground 10 k ohms or higher RD-5 - Body ground Below 1 ohms RD-7 - Body ground Below 1 ohms NG: REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go To Next Step
- CHECK COWL SIDE JUNCTION BLOCK RH (ACC RELAY)
- Disconnect the RN J/B connector.
- Measure the resistance of the J/B connectors.
Standard resistance
COWL SIDE JUNCTION BLOCK RH (ACC RELAY) (RESISTANCE)Tester Connection Condition Specified Condition RN-1 - RD-27 or RD-26 When battery voltage is not applied to terminals RD-2 and RD-7 or RD-5 10 k ohms or higher RN-1 - RD-27 or RD-26 When battery voltage is applied to terminals RD-2 and RD-7 or RD-5 Below 1 ohms Result
