STEP 1. Using scan tool (M.U.T.-IIISE), diagnose the 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 check result normal?
Go to Step 3. Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ). On completion, go to Step 2.
STEP 2. DTC recheck after resetting CAN bus lines.
STEP 4. Charging system check.
STEP 5. Voltage measurement at the ASC-ECU connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the voltage between the +BV terminal and the body ground.OK: Approximately system voltage
Is the check result normal?
Go to Step 7. Go to Step 6.
STEP 6. Check of short to power supply, short to ground, and open circuit in +BV line between fusible link and ASC-ECU connector.
Is the check result normal?
Go to Step 7. : Repair the fusible link, connector(s) or wiring harness.
STEP 7. Resistance measurement at ASC-ECU connector.
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Resistance between the GND1 terminal and the body ground, and between the GND2 terminal and the body ground.OK: Continuity exists (2 Ω or less)
Is the check result normal?
Go to Step 9. Go to Step 8.
STEP 8. Check of open circuit in GND1, GND2 line between ASC-ECU connector and body ground.
Is the check result normal?
Go to Step 9. : Repair the connector(s) or wiring harness.
STEP 9. Check whether the DTC is set again.
STEP 10. Check whether the DTC is set again.
(1) Erase the DTC.
(2) Drive the vehicle at 20 km/h (12 mph) or higher.note | The ABS warning light does not turn OFF in some cases unless the vehicle runs at 20 km/h (12 mph) or higher. |
Is any DTC set?
Carry out the applicable troubleshooting for the DTC (Refer to ). : The procedure is complete.
