DIAGNOSIS
HEADLAMPS–ON REMINDER CHIME
Diagnostic Aids :
The fuse for the left–side taillamps is also part of the headlamps–on reminder chime circuit. The headlamps–on reminder
chime should operate when the ignition is OFF, the headlamps or parking lamps are on, and the driver door is open.
Headlamps–On Reminder Chime Does Not Work
StepActionValue(s)YesNo
1Turn the parking lamps on, and observe the tail-
lamps.
Are the taillamps operating correctly?–Go to Step 3Go to Step 2
2Repair the left–side taillamps before completing this
diagnostic table.
After the taillamps have been repaired, does the
headlamps–on reminder chime work?–System OKGo to Step 3
31. Disconnect the chime module electrical con-
nector.
2. Turn the headlamps on.
3. Check the voltage at terminal 6 of the chime
module connector.
Is the voltage equal to the specified value?11–14 vGo to Step 5Go to Step 4
4Repair the open circuit between fuse Ef23 and termi-
nal 6 of the chime module connector.
Is the repair complete?–System OK–
5Use an ohmmeter to check the resistance between
ground and terminal 5 of the chime module.
Is the resistance equal to the specified value?
0 WGo to Step 7Go to Step 6
6Repair the open circuit between ground and terminal
5 of the chime module.
Is the repair complete?–System OK–
71. Remove the driver door contact switch.
2. Remove the electrical connector from the driv-
er door contact switch.
3. Use an ohmmeter to measure the resistance
between the driver door contact switch connec-
tor and the chime module terminal 4.
Does the ohmmeter indicate the specified value?
0 WGo to Step 9Go to Step 8
8Repair the open circuit between the driver door con-
tact switch connector and the chime module termi-
nal 4.
Is the repair complete?–System OK–
91. Connect the electrical connector to the chime
module.

equal the value specified?11–14 vGo to Step 4Go to Step 9
41. Disconnect both headlamp connectors.
2. Turn the headlamps ON.
3. Select the low beams.
Does the voltage at each headlamp connector termi-
nal 5 equal the value specified?11–14 vGo to Step 6Go to Step 5
5Repair the open circuit between fuses Ef20 or Ef27
and the low beam headlamps.
Is the repair complete?–System OK–
61. Disconnect the headlamp connectors.
2. Connect an ohmmeter between ground and
either headlamp connector terminal 6.
Is the resistance equal to the value specified?0 WGo to Step 8Go to Step 7
7Repair the ground circuit.
Is the repair complete?–System OK–
8Replace the faulty headlamps.
Is the repair complete?–System OK–
91. Disconnect the headlamp switch connector.
2. Select the low beams.
3. Use an ohmmeter to check the continuity be-
tween terminals 6 and 5 of the headlamp
switch.
Does the ohmmeter indicate the value specified?0 WGo to Step 10Go to Step 11
10Replace the headlamp combination switch.
Is the repair complete?–System OK–
11Repair the open circuit between fuses Ef20 and Ef27
and the headlamp switch connector terminal 5.
