NOTE: Also check intermediate connector D-26 and junction 
block connector D-207 for loose, corroded, or damaged termi-
nals, or terminals pushed back in the connector. If junction 
block connector D-207 or intermediate connector D-26 is dam-
aged, repair or replace the damaged component(s) as 
described in GROUP 00E, Harness Connector Inspection

. 

Q: Is the wiring harness between cargo space light 

connector F-08 (terminal 2) and ETACS-ECU connector 
D-222 (terminal 18) in good condition?
YES : Replace the ETACS-ECU. Verify that the cargo space 

light illuminates normally.

NO :  Repair the wiring harness. Verify that the cargo space 

light illuminates normally.

STEP 22. Check the cargo space light bulb.
Q: Is the cargo space light bulb in good condition?

YES : Go to Step 23.
NO :  Replace the bulb. Verify that the cargo space light 

illuminates normally.

STEP 23. Check cargo space light connector F-08 for 
damage.
Q: Is cargo space light connector F-08 in good condition?

YES : Go to Step 24.
NO :  Repair or replace the connector. Refer to GROUP

STEP 24. Check the fusible link (1) line of the power supply 
circuit to the cargo space light. Test at cargo space light 
connector F-08.
(1) Disconnect cargo space light connector F-08 and measure 

the voltage available at the wiring harness side of the 
connector.

(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 cargo space light. Verify that the cargo 

space light illuminates normally.

NO :  Go to Step 25.

STEP 25. Check the wiring harness between cargo space 
light connector F-08 (terminal 1) and fusible link (1).

.

Q: Is the wiring harness between cargo space light 

connector F-08 (terminal 1) and fusible link (1) in good 
condition?
YES : No action to be taken.
NO :  Repair the wiring harness. Verify that the cargo space 

light illuminates normally.

STEP 26. Check the rear personal light (LH).
Q: Does the dome light illuminate when the rear personal 

light (LH) switch is turned to the "ON" position?
