STEP 5. Check the dome light and cargo space light power 
supply circuit at dome light connector E-20 <vehicles with 
sunroof> or E-21 <vehicles without sunroof> and cargo 
space light connector E-16.

(1) Disconnect dome light connector E-20 <vehicles with 

sunroof> or E-21 <vehicles without sunroof>, cargo space 
light connector E-16 and measure at the harness side.

(2) Measure the voltage between terminal 1 and ground.

• The measured value should be approximately 12 volts 

(battery positive voltage).

Q: Does the measured voltage correspond with this range?

YES : Replace the dome light or cargo space light. The 

dome light and cargo space light should illuminate.

NO :  Go to Step 6.

NOTE: After checking junction block connector D-01 and D-07, 
IOD or storage connector A-54X, check the wires. If junction 
block connector D-01 and D-07, IOD or storage connector 
A-54X are damaged, repair or replace them. Refer to GROUP 
00E, Harness Connector Inspection 

P.00E-2

. 

Q: Are the harness wires between dome light connector 

E-20 (terminal No.1) <vehicles with sunroof> or E-21 
(terminal No.1) <vehicles without sunroof>, cargo space 
light connector E-16 (terminal No.1) and fusible link 
number 8 in good condition?
YES : Go to Step 8.
NO :  Repair them. The dome light and cargo space light 

should illuminate.

STEP 8. Recheck for malfunction.
Q: Is a malfunction eliminated?

YES : The procedure is complete. (If no malfunctions are 

found in all steps, an intermittent malfunction is 
suspected. Refer to GROUP 00, How to Use 
Troubleshooting/Inspection Service Point
