STEP 1. Check the GW-CAN-C for short to power supply. Voltage measurement at gateway-ECU connector by backprobing.
caution | A digital multimeter should be used. For details refer to . |
caution | The test wiring harness should be used. For details refer to . |
(1) Connect the negative battery terminal, and turn the ignition switch to the ON position.
(2) Voltage between the gateway-ECU connector terminal No.6 (CAN_H) and body ground by backprobingOK: Less than 4.0 V
(3) Voltage between the gateway-ECU connector terminal No.5 (CAN_L) and body ground by backprobingOK: Less than 4.0 V
(4) Disconnect the negative battery terminal.
Is the check result normal?
Go to Step 2. Perform diagnostic item 6 "Diagnose shorts in the power supply to GW-CAN-C". Refer to .
