Inspection Procedure 3: Any of the sunshade illuminations does not illuminate normally: Diagnosis
- STEP 1. Sunshade illumination operation check
Check if the sunshade illumination turns ON normally.
Q: Is the check result normal?
YES (normal for all) : The diagnosis is complete.
NO (Only the RH side does not illuminate.): Go to Step 2.
NO (Only the LH side does not illuminate.): Go to Step 4.
- STEP 2. Check sunshade illumination (RH) connector E-10 and the intermediate connector E-14 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is sunshade illumination (RH) connector E-10 and the intermediate connector E-14 in good condition?
YES : Go to Step 3.
NO : Repair or replace the damaged component(s). (Refer to HARNESS CONNECTOR INSPECTION .)
- STEP 3. Check the wiring harness between sunshade illumination (RH) connector E-10 terminal 1, 2 and the intermediate connector E-14 terminal 3, 4
- Check the power supply lines and ground wires for open and short circuit.
Q: Is the wiring harness between sunshade illumination (RH) connector E-10 terminal 1, 2 and the intermediate connector E-14 terminal 3, 4 in good condition?
YES : Go to Step 6.
NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary.
- STEP 4. Check sunshade illumination (LH) connector E-13 and the intermediate connector E-14 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is sunshade illumination (LH) connector E-13 and the intermediate connector E-14 in good condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). (Refer to HARNESS CONNECTOR INSPECTION .)
- STEP 5. Check the wiring harness between sunshade illumination (LH) connector E-13 terminal 1, 2 and the intermediate connector E-14 terminal 3, 4
- Check the power supply lines and ground wires for open and short circuit.
Q: Is the wiring harness between sunshade illumination (LH) connector E-13 terminal 1, 2 and the intermediate connector E-14 terminal 3, 4 in good condition?
YES : Go to Step 6.
NO : The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary.
- STEP 6. Retest the system
Check if the sunshade illumination turns ON normally.
Q: Is the check result normal?
YES : The trouble can be an intermittent malfunction (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS ).
NO : Replace the spot light assembly that does not illuminate.
