STEP 4. Check that the malfunction is eliminated
Q: Is the malfunction eliminated?
YES : It can be assumed that this malfunction is intermittent.
(Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunction
).
NO : Replace the auto-cruise control-ECU. (Refer to
). Then go to Step 5 .
STEP 5. Check that the malfunction is eliminated
Q: Is the malfunction eliminated?
YES : This procedure is complete.
NO : Return to Step 1 .

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 auto-cruise control-ECU
illuminates the auto-cruise indicator through ECU ter-
minal number 15.
.
TECHNICAL DESCRIPTION (COMMENT)
The cause is probably the malfunction of the indica-
tor bulb or the malfunction of the connector or har-
ness.
.

DIAGNOSIS
Required Special Tool:
• MB991223: Harness set
STEP 1. Check the auto-cruise control indicator bulb.
(1) Remove the combination meter. (Refer to GROUP 54,
Combination Meter Assembly
(2) Check the auto-cruise control indicator bulb.
Q: Is the bulb blown?
YES : Replace the bulb. Then go to Step 11 .
NO : Go to Step 2 .
STEP 2. Measure the output circuit voltage at auto-cruise
control-ECU connector C-35 by backprobing.
(1) Do not disconnect auto-cruise control-ECU connector C-35.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between auto-cruise control-ECU
connector C-35 terminal 15 and ground by backprobing.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is measure voltage approximately battery positive
voltage?
YES : Go to Step 10 .
NO : Go to Step 3 .
