STEP 1. Check the GW-CAN-C. Voltage 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 BSW-ECU (master) connector, and measure at the wiring harness side.
(2) Connect the negative battery terminal, and turn the ignition switch to the ON position.
(3) Voltage between the gateway-ECU connector terminal No.6 (CAN_H) and body ground.OK: 4.0 V or less
(4) Voltage between the gateway-ECU connector terminal No.5 (CAN_L) and body ground.OK: 4.0 V or less
(5) Disconnect the negative battery terminal.
Is the check result normal?
<4.0 V or less> Go to Step 2. <More than 4.0 V> Repair intermediate connectors C-25 and G-36, or the wiring harness between the gateway-ECU connector and the BSW-ECU (master) connector.
