STEP 2. Continuity check between data link connector and 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 . |
caution | Strictly observe the specified wiring harness repair procedure. For details refer to . |
(1) Disconnect the scan tool (M.U.T.-IIISE) and gateway-ECU connector and measure at the wiring harness side.
(2) Turn the ignition switch to the "LOCK" (OFF) position.caution | When measuring the resistance, disconnect the negative battery terminal. For details refer to . |
(3) Ensure that the negative battery terminal is disconnected.
(4) Check the continuity between data link connector terminal No. 6 and gateway-ECU connector terminal No. 29. <CAN_H>OK: The resistance should be 2 ohms or less.
(5) Check the continuity between data link connector terminal No. 14 and gateway-ECU connector terminal No. 28. <CAN_L>OK: The resistance should be 2 ohms or less.
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 the data link connector and gateway-ECU connector.
