CIRCUIT OPERATION
The power for the auto-cruise indicator in the combi-
nation meter is supplied from the ignition switch
(IG1). When the auto-cruise control system is operat-
ing, the transistor inside the PCM illuminates the
auto-cruise indicator through PCM terminal number
13.
.
COMMENT
The cause is probably the malfunction of the indica-
tor bulb or the malfunction of the connector or har-
ness.
.
TROUBLESHOOTING HINTS
• Malfunction of the indicator bulb.
• Damaged harness or connector.
• Malfunction of the PCM.

DIAGNOSIS
.
Required Special Tool:
• MB991223: Harness Set
STEP 1. Check the auto-cruise control indicator bulb.
(1) Remove the combination meter. Refer to GROUP 54A,
Combination Meter Assembly and Vehicle Speed Sensor
.
(2) Check the auto-cruise control indicator bulb.
Q: Is the bulb blown?
YES : Replace the bulb. Then check that the malfunction is
eliminated.
NO : Go to Step 2.
STEP 2. Measure the power supply voltage at combination
meter connector D-03.
(1) Disconnect connector D-03 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Switch "ON" the auto-cruise control main switch.
(4) Measure the voltage between terminal 62 and ground.
• The voltage should measure battery positive voltage.
Q: Is the measured voltage battery positive voltage?
YES : Go to Step 5.
NO : Go to Step 3.

STEP 3. Check combination meter connector D-03 and
junction block connector D-210 for looser, corroded or
damaged terminals, or terminals pushed back in the
connector.
Q: Are the connectors and terminals in good condition?
YES : Go to Step 4.
NO : Repair or replace the damaged components. Refer to
GROUP 00E, Harness Connector Inspection
STEP 4. Check the harness for open circuit or short circuit
to ground between combination meter connector D-03
terminal 62 and junction block connector D-210 terminal 1.
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair or replace the harness wire.
