STEP 3. Check the wiring harness between map lamp
assembly connector D-02 (terminals 1 and 2) <without
sunroof> or overhead console assembly connector D-03
(terminals 1 and 2) <with sunroof> and ETACS-ECU
connector C-219 (terminals 6 and 5).
Q: Is the wiring harness between map lamp assembly

connector D-02 (terminals 1 and 2) <without sunroof> or
overhead console assembly connector D-03 (terminals
1 and 2) <with sunroof> and ETACS-ECU connector
C-219 (terminals 6 and 5) in good condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Check that
the front dome lamp and rear dome lamp illuminates
normally.

STEP 4. Check map lamp assembly connector D-02
<without sunroof> or overhead console assembly
connector D-03 <with sunroof> for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Is map lamp assembly connector D-02 <without

sunroof> or overhead console assembly connector
D-03 <with sunroof> in good condition?
YES : Go to Step 5.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Check that the front dome lamp illuminates

normally.

STEP 5. Check the front dome lamp bulb.

Q: Is the front dome lamp bulb in good condition?

YES : Go to Step 6.

STEP 6. Check the ground circuit to the front dome lamp.
Measure the resistance at map lamp assembly connector
D-02 <without sunroof> or overhead console assembly
connector D-03 <with sunroof>.
(1) Disconnect map lamp assembly connector D-02 <without

sunroof> or overhead console assembly connector D-03
<with sunroof> and measure the resistance available at the
wiring harness side of the connector.

(2) Measure the resistance value between terminal 3 and

ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 8.
NO : Go to Step 7.

STEP 7. Check the wiring harness between map lamp
assembly connector D-02 (terminal 3) <without sunroof>
or overhead console assembly connector D-03 (terminal 3)
<with sunroof> and ground.
Q: Is the wiring harness between map lamp assembly

connector D-02 (terminal 3) <without sunroof> or
overhead console assembly connector D-03 (terminal 3)
<with sunroof> and ground in good condition?
YES : Replace the overhead console assembly. Check that

the front dome lamp illuminates normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Check that
the front dome lamp illuminates normally.

STEP 8. Check the wiring harness between map lamp
assembly connector D-02 (terminals 1 and 2) <without
sunroof> or overhead console assembly connector D-03
(terminals 1 and 2) <with sunroof> and ETACS-ECU
connector C-219 (terminals 6 and 5).
Q: Is the wiring harness between map lamp assembly

or overhead console assembly <with sunroof>. Check
that the front dome lamp illuminates normally.

NO : The wiring harness may be damaged or the

connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. Check that
the front dome lamp illuminates normally.

STEP 9. Check rear dome lamp connector D-07 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q: Is rear dome lamp connector D-07 in good condition?

YES : Go to Step 10.
NO : Repair or replace the damaged component(s). Refer

to GROUP 00E, Harness Connector Inspection

P.00E-2

. Check that the rear dome lamp illuminates

normally.

STEP 10. Check the rear dome lamp bulb.

Q: Is the rear dome lamp bulb in good condition?

YES : Go to Step 11.
NO : Replace the rear dome lamp bulb. Check that the rear

dome lamp illuminates normally.
