SYMPTOM PROCEDURES

The back-up lamps do not illuminate normally.

COMMENTS ON TROUBLE SYMPTOM

When the back-up lamp does not illuminate or extin-
guish normally, the power supply or the earth circuit 
to the back-up lamp or the inhibitor switch may be 
defective.

PROBABLE CAUSES

• Malfunction of the inhibitor switch

• Malfunction of bulbs

• Malfunction of the back-up lamp assembly

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

STEP 1. Bulb check
Check the bulb(s) of the lamp that does not illumi-
nate.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Replace the bulb(s) of the lamp that does 
not illuminate.

STEP 2. M.U.T.-III diagnosis code
Check if diagnosis code is set to the ETACS-ECU.

Q: Is the diagnosis code set?

YES : 

Troubleshoot the ETACS-ECU. Refer to 

P.54A-281

.

NO : 

Go to Step 3.

STEP 3. Check the inhibitor switch.
Check the continuity of the inhibitor switch. (GROUP 
23A 

− On-vehicle Service, Inhibitor Switch Continuity 

Check .)

Q: Is the check result normal?

YES : 

Go to Step 4

NO : 

Replace the inhibitor switch.

STEP 4. Voltage measurement at the inhibitor 
switch connector (power supply terminal).
(1) Remove the inhibitor switch connector, and 

measure at the junction block side.

(2) Move the ignition switch to the ON position.
(3) Measure the voltage between the inhibitor switch 

connector (power supply terminal) and body 
earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 6

NO : 

Go to Step 5

STEP 5. Check of open circuit in power supply 
line between the inhibitor switch connector and 
the fusible link.

Q: Is the check result normal?

YES : 

Go to Step 6

NO : 

Repair the connector(s) or wiring harness.

STEP 6. Resistance measurement at the back-up 
lamp connector (earth terminal).
(1) Disconnect the connector, and measure at the 

wiring harness side.

(2) Measure the resistance between the back-up 

lamp connector (earth terminal) and the body 
earth.

OK: Continuity exists (2 

Ω or less)

Q: Is the check result normal?

YES : 

Go to Step 8

NO : 

Go to Step 7

STEP 7. Check of open circuit in earth line 
between the back-up lamp connector and body 
earth.

Q: Is the check result normal?

YES : 

Go to Step 8

NO : 

Repair the connector(s) or wiring harness.

STEP 8. Check of open circuit in output line 
between the back-up lamp connector and 
inhibitor switch connector.

Q: Is the check result normal?

YES : 

Go to Step 9

NO : 

Repair the connector(s) or wiring harness.

STEP 9. Retest the system
Check that the back-up lamp illuminate normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction ).

NO : 

Replace the back-up lamp assembly.
