STEP 1. Check the GW-CAN-C. Resistance measurement at gateway-ECU 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 gateway-ECU connector and the BSW-ECU (master) connector, and measure at the wiring harness side.
(2) caution | When measuring the resistance, disconnect the negative battery terminal. For details refer to . |
Ensure that the negative battery terminal is disconnected.
(3) Resistance between the gateway-ECU connector terminal No.6 (CAN_H) and body ground.OK: 1 kΩ or more
(4) Resistance between the gateway-ECU connector terminal No.5 (CAN_L) and body ground.OK: 1 kΩ or more
Is the check result normal?
<1 kΩ or more> Go to Step 2. <Less than 1 kΩ > Repair intermediate connectors C-25 and G-36, or the wiring harness between the gateway-ECU connector and the BSW-ECU (master) connector.
