STEP 4. Check the harness wire between park/neutral
position switch connector B-01 (terminal No.10) and
auto-cruise control-ECU connector C-35 (terminal No.13).
Q: Is any harness wire between park/neutral position
switch connector B-01 (terminal No.10) and auto-cruise
control-ECU connector C-35 (terminal No.13) damaged?
YES : Repair or replace the harness wire. Then go to Step 6
NO : 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
).
STEP 5. 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 6 .
STEP 6. Check that the malfunction is eliminated
Q: Is the malfunction eliminated?
YES : This procedure is complete.
NO : Return to Step 1 .

INSPECTION PROCEDURE 4: When the Auto-cruise Control "CANCEL" Switch is Set to ON,
Auto-cruise Control is not Cancelled.
.
TECHNICAL DESCRIPTION (COMMENT)
The cause is probably an open-circuit in the output in
the circuit inside the "CANCEL" switch.
.
TROUBLESHOOTING HINTS
• Malfunction of the auto-cruise control switch
DIAGNOSIS
Replace the auto-cruise control switch. (Refer to
Then check the malfunction is eliminated.
INSPECTION PROCEDURE 5: Auto-cruise Control cannot be Set.
.
TECHNICAL DESCRIPTION (COMMENT)
The fail-safe function is probably cancelling
auto-cruise control.
In this case, scan tool MB991958 can be used to
check the trouble symptoms in each system by
checking the diagnostic trouble codes.
The scan tool MB991958 can also be used to check
if the circuits of each input switch are normal or not
by checking the input switch codes.
.
TROUBLESHOOTING HINTS
• Malfunction of the auto-cruise control switch.
• Malfunction of the auto-cruise control switch.
• Malfunction of the auto-cruise control-ECU.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan tool (MUT-III sub assembly)
• MB991824: V.C.I.
• MB991827: MUT-III USB cable
• MB991911: MUT-III main harness B
• MB991223: Harness set

NO : Inspect each trouble symptom. (Refer to Inspection
Procedure number 1
STEP 2. Using scan tool MB991958, check the any DTC set.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Using scan tool MB991958.
(2) Connect scan tool MB991958 to the data link connector.
(3) Turn the ignition switch to the "ON" position.
(4) Read the DTC.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
(6) Disconnect scan tool MB991502.
Q: Is any DTC set?
YES : DTC 11, 12, 14, 15, 16 or 17 is set, (Refer to
