STEP 7. Check the wiring harness between dome light 
connector F-03 (terminal 2) and ETACS-ECU connector D-
222 (terminal 18).

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 

P.00E-2

. 

Q: Is the wiring harness between dome light connector F-

03 (terminal 2) and ETACS-ECU connector D-222 
(terminal 18) in good condition?
YES : Replace the ETACS-ECU. Verify that the dome light 

illuminates normally.

NO :  Repair the wiring harness. Verify that the dome light 

illuminates normally.

STEP 8. Check the dome light bulb.
Q: Is the dome light bulb in good condition?

YES : Go to Step 9.
NO :  Replace the bulb. Verify that the dome light 

illuminates normally.

STEP 9. Check the fusible link (1) line of the power supply 
circuit to the dome light. Test at dome light connector F-03.
(1) Disconnect dome light connector F-03 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 dome light. Verify that the dome light 

illuminates normally.

NO :  Go to Step 10.

STEP 10. Check dome light connector F-03 for damage.
Q: Is dome light connector F-03 in good condition?

YES : Go to Step 11.
NO :  Repair or replace the connector. Refer to GROUP 

00E, Harness Connector Inspection
