Inspection Procedure 4

Inspection Procedure 4: The foot light does not illuminate normally.






















TROUBLE JUDGMENT

If the foot light does not illuminate normally, the power supply circuit(s), ground circuit, or under cover rear may have a problem.

TROUBLESHOOTING HINTS

- Malfunction of under cover rear

- Damaged harness wires and connectors

DIAGNOSIS

STEP 1. Check electric foot light connector D-102 (RH), D-120 (LH) for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q. Is the check result normal?

YES Go to Step 2.
NO Repair the defective connector.
STEP 2. Measure the voltage at foot light connector D-102 (RH), D-120
(LH).

(1)Disconnect the connector, and measure at the wiring harness side.





(2)Measure the voltage between the D-102 (RH), D-120 (LH) electric folding second seat connector (terminal No. 1) and the ground.
The voltage should measure approximately 12 volts (battery positive voltage).


Q. Does the voltage measure battery voltage?

YES Go to Step 4.

NO Go to Step 3.

STEP 3. Check the wiring harness between foot light connector D-102
(RH), D-120 (LH) (terminal No. 1) and the fusible link (34).

Check the power supply line for open or short circuit.

NOTE:
Before the wiring harness check, check the relay box connector C-308, and the intermediate connector C-35, C-32 and then repair them if necessary.

Q. Is wiring harness between foot light connector D-102 (RH), D-120 (LH) (terminal No.
1) and the fusible link (34) in good condition?

YES The trouble can be an intermittent malfunction How to Cope With Intermittent Malfunctions).
NO Repair the wiring harness.
STEP 4. Measure the resistance at foot light connector D-102 (RH), D-120 (LH).

(1)Disconnect the connector, and measure at the wiring harness side.





(2)Measure the resistance between the resistance at foot light connector D-102 (RH), D-120
(LH) (terminal No. 5) and ground.
The measured value should be continuity exists (2 ohms
or less).

Q. Does the measured resistance value correspond with this range?

YES Go to Step 6.

NO Go to Step 5.

STEP 5. Check the wiring harness between foot light connector D-102
(RH), D-120 (LH) (terminal No. 5) and ground.

Check the ground line for open circuit.

Q. Is wiring harness between foot light connector D-102 (RH), D-120 (LH) (terminal No.
5) and ground in good condition?

YES The trouble can be an intermittent malfunction How to Cope With Intermittent Malfunctions).
NO Repair the wiring harness.
STEP 6. Retest the system.

Check that the foot light illuminates normally.

Q. Is the check result normal?

YES The trouble can be an intermittent malfunction How to Cope With Intermittent Malfunctions).
NO Replace the under cover rear.
