Inspection Procedure 4

Inspection Procedure 4: The Foot Light Does Not Illuminate Normally.

Foot Light Circuit (Part 1):

Foot Light Circuit (Part 2):

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).

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 (Refer to general (Body and Chassis) How to use Troubleshooting/inspection Service Points How to Cope with Intermittent Malfunction).

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.

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 (Refer to general (Body and Chassis) How to use Troubleshooting/inspection Service Points How to Cope with Intermittent Malfunction).

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 (Refer to general (Body and Chassis) How to use Troubleshooting/inspection Service Points How to Cope with Intermittent Malfunction).

NO : Replace the under cover rear.
