STEP 3. Check the circuit at the park/neutral position 
switch.
(1) Disconnect the park/neutral position switch connector B-01.

(2) Measure the continuity park/neutral position switch side 

connector B-01 terminals.

Q: Is the continuity meet the table above?

YES : Go to Step 4 .
NO :  Replace the park/neutral position switch. (Refer to 

GROUP 23B, Transmission 

P.23B-19

). Then go to 

Step 6 .

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 

P.00-7

).

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 

P.00-7

).

NO :  Replace the auto-cruise control-ECU. (Refer to 

P.17-99

). 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 

P.17-99

). 

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

STEP 1. Can the auto-cruise control-ECU communicate 
with scan tool MB991958?

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) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
Q: Can the auto-cruise control-ECU communicate with the 

scan tool?
YES : Go to Step 2 .
NO :  Inspect each trouble symptom. (Refer to Inspection 

Procedure number 1 

P.17-54

).

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.
