STEP 1. Using scan tool (M.U.T.-IIISE), diagnose CAN bus line.
(1) caution | To prevent damage to scan tool (M.U.T.-IIISE), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-IIISE). |
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect the Scan Tool (M.U.T.-IIISE)
."
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the CAN bus line found to be normal?
Go to Step 2. Repair the CAN bus line (Refer to GROUP 54C - Troubleshooting - CAN Bus Diagnostics Table ).
STEP 2. Using scan tool (M.U.T.-IIISE), check whether the DTC is set.
STEP 3. Using scan tool (M.U.T.-IIISE), check whether the other system DTC is set.
STEP 4. Resistance measurement at the combination meter connector
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the combination meter connector (GND1 terminal) and the body ground.OK: The resistance should be 2 ohms or less
Is the check result normal?
Go to Step 6 Go to Step 5
STEP 5. Check of short to ground circuit in GND1 line between combination meter connector and body ground.
STEP 6. Voltage measurement at the combination meter connector
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the voltage between the combination meter connector (IL+P terminal) and the body ground.OK: The voltage should measure approximately 12 volts (battery positive voltage)
Is the check result normal?
Go to Step 9 Go to Step 7
STEP 7. Check of short to power supply circuit in IL+P line between the fusible link and combination meter connector.
STEP 8. Check of short to power supply circuit in ILL+ line between the combination meter connector and multi-information display switch connector.
STEP 9. Using scan tool (M.U.T.-IIISE), check special function.
STEP 10. Retest the system.
