STEP 2. Resistance measurement at joint connector (CAN1) <Vehicles without ACC> or joint connector (CAN2) <Vehicles with ACC> and ECM connector.
caution | A digital multimeter should be used. For details refer to . |
caution | The test wiring harness should be used. For details refer to . |
(1) Disconnect the joint connector (CAN1) <Vehicles without ACC> or joint connector (CAN2) <Vehicles with ACC> and the ECM connector, and measure at the wiring harness side.
(2) Turn the ignition switch to the LOCK (OFF) position.
(3) caution | When measuring the resistance, disconnect the negative battery terminal. For details refer to . |
Ensure that the negative battery terminal is disconnected.
(4) Continuity between joint connector (CAN1) terminal No.8 and ECM connector terminal No.90 <Vehicles without ACC>OK: Continuity (2 ohms or less)
(5) Continuity between joint connector (CAN1) terminal No.17 and ECM connector terminal No.91 <Vehicles without ACC>OK: Continuity (2 ohms or less)
(6) Continuity between joint connector (CAN2) terminal No.10 and ECM connector terminal No.90 <Vehicles with ACC>OK: Continuity (2 ohms or less)
(7) Continuity between joint connector (CAN2) terminal No.21 and ECM connector terminal No.91 <Vehicles with ACC>OK: Continuity (2 ohms or less)
caution | Strictly observe the specified wiring harness repair procedure. For details refer to . |
Is the check result normal?
<All the resistances measure 2 ohms or less> Go to Step 3. : <Either or all of the resistances measure more than 2 ohms> Repair the wiring harness between joint connector (CAN1) <Vehicles without ACC> or joint connector (CAN2) <Vehicles with ACC> and the ECM.
