TROUBLESHOOTING LOCAL INTERCONNECT NETWORK (LIN) 54B-11 DIAGNOSIS PROCEDURE STEP 1. Connector check: C-316 ETACS-ECU Q: Is the check result normal? YES : Go to Step 2. NO : Repair the defective connector. STEP 2. Resistance measurement at the D-02 wiring harness side. (2) Measure the resistance between the D-02 lighting control sensor connector terminal No. 2 OK: Continuity exists (2 Ω or less) Q: Is the check result normal? YES : Go to Step 4. NO : Go to Step 3. STEP 3. Wiring harness check from D-02 lighting Q: Is the check result normal? YES : The trouble can be an intermittent malfunction (Refer to GROUP 00 − How to use Troubleshooting/inspection Service − How to Cope with Intermittent Malfunction ). NO : Repair the wiring harness. STEP 4. Voltage measurement at the D-02 wiring harness side. (2) Measure the voltage between the D-02 lighting control sensor connector terminal No. 1 and the OK: System voltage Q: Is the check result normal? YES : Go to Step 6. NO : Go to Step 5. STEP 5. Wiring harness check between the D-02 Q: Is the check result normal? YES : The trouble can be an intermittent malfunction (Refer to GROUP 00 − How to use Troubleshooting/inspection Service − How to Cope with Intermittent Malfunction ). NO : Repair the wiring harness. STEP 6. Check the wiring harness wires between Q: Is the check result normal? YES : Go to Step 7. NO : Repair the wiring harness. STEP 7. Check whether the diagnosis code is position to the ON position. (3) Check if diagnosis code is set. Q: Is the diagnosis code set? YES : Replace the lighting control sensor. NO : A poor connection, open circuit, or other − How to Cope with Intermittent Malfunction ). |
