ILL (RED)
GAUGE CONTROL MODULE (TACH) 36P CONNECTOR ILL (RED)
AUDIO UNIT CONNECTOR A (17P) ILL (GRY)NOTE: Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Turn the ignition switch to ON (II).
2. Turn the combination lighting switch to the parking light position.
3. Check the illumination of the audio unit buttons.
Intermittent problem: the audio unit is OK at
this time. Check for loose or poor connections at
the audio unit connector A (17P).
Go to step 4.
4. Check the illumination of several other buttons not relatedtotheaudiosystem.
Go to step 5.
Troubleshoot the interior lights. Start by
checking the No. 14 (7.5 A) fuse in the under-dash
fuse/relay box. If the fuse is OK, check for an open
in the wire between the under-dash fuse/relay box
and the audio unit.
5. Turn the ignition switch to LOCK (0).
6. Disconnect audio unit connector A (17P). NOTE: Eject all the discs before removing the audio
unit to prevent damaging the CD player’s load
mechanism.
7. Disconnect gauge control module (tach) 36P connector. 8. Check for continuity between audio unit connector
A (17P) terminal No. 1 and gauge control module
(tach) 36P connector terminal No. 14.
Go to step 9.
Repair open in the wire between the gauge
control module and the audio unit.
9. Turn the ignition switch to ON (II).
10. With the headlight switch still on, measure the voltage between audio unit connector A (17P)
terminal No. 10 and body ground.
Check the connections at audio unit
connector A (17P). If all the connections are OK,
replace the audio unit (see page 23-256).
Repair open in the wire between the under-
dash fuse/relay box and the audio unit.

NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Turn the ignition switch to ON (II).
2. Turn the combination light switch ON and OFF to see if the symptom can be duplicated.
Go to step 3.
Operation is normal.
3. Turn the combination light switch to OFF.
4. Rotate the illumination control dial.
Operation is normal.
Go to step 5.
5. Disconnect, and check audio unit connector A (17P) for a loose or a poor connection.
NOTE: Eject all the discs before removing the audio
unit to prevent damaging the CD player’s load
mechanism.
Go to step 6.
Operation is normal.
6. Turn the ignition switch to LOCK (0).
7. Remove the audio unit (see page 23-256). 8. Turn the ignition switch to ON (II).
9. Measure the voltage between audio unit connector
A (17P) terminals No. 1 and No. 10. Rotate the dash
brightness controller buttons to see if the voltage
changes.
Substitute a known-good audio unit
(see page 23-256), and recheck. If the symptom/
indication goes away, replace the original audio
unit. If symptom is still present, substitute a known-
good center panel display and recheck. If the
symptom/indication goes away, replace the
original center panel display (see page 23-256).
Repair open in the wire between the under-
dash fuse/relay box and the gauge control
module.
