CIRCUIT OPERATION

This circuit judges the signals of each switch 
("ON/OFF", "CANCEL", "COAST/SET" and 
"ACC/RES") of the cruise control switch. The ECM 
detects the state of the cruise control switch by sens-
ing the voltages shown below.

• When all switches are released: 4.7 − 5.0 volts

• When the "ON/OFF" switch is pressed: 0 − 0.5 

volt 

• When the "CANCEL" switch is pressed: 1.0 − 1.8 

volts 

• When the "COAST/SET" switch is pressed: 2.3 − 

3.0 volts 

• When the "ACC/RES" switch is pressed: 3.5 − 

4.2 volts 

.

DTC SET CONDITIONS

Check Condition

• The "CRUISE" indicator light illuminates.

Judgment Criteria

• This DTC is set when the ECM terminal voltage is 

different from the standard value.

• Or, this DTC is set when the "COAST/SET" 

switch or "ACC/RES" switch is stuck to ON.

.

TROUBLESHOOTING HINTS (THE MOST 
LIKELY CAUSES FOR THIS CASE:)

• Damaged harness or connector.

• Malfunction of the cruise control switch.

• Malfunction of the clock spring.

• Malfunction of the ECM.

STEP 1. Using scan tool MB991958, check the data list 
item 86: Main switch, item 92: Set switch, item 91: Resume 
switch and item 75: Cancel switch.

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 

(Refer to 

P.17-12

).

(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for cruise 

control system (Refer to 

P.17-12

).

• Item 75: Cancel switch.

• When "CANCEL" switch is pressed, the display on 

scan tool MB991958 should be "ON".

• When "CANCEL" switch is released, the display on 

scan tool MB991958 should be "OFF".

• Item 86: Main switch.

• When "ON/OFF" switch is pressed, the display on 

scan tool MB991958 should be "ON".

• When "ON/OFF" switch is pressed again, the display 

on scan tool MB991958 should be "OFF".

• Item 91: Resume switch.

• When "ACC/RES" switch is pressed, the display on 

scan tool MB991958 should be "ON".

• When "ACC/RES" switch is released, the display on 

scan tool MB991958 should be "OFF".

• Item 92: Set switch.

• When "COAST/SET" switch is pressed, the display 

on scan tool MB991958 should be "ON".

• When "COAST/SET" switch is released, the display 

on scan tool MB991958 should be "OFF".

Q: Is the switch operating properly?

YES : Go to Step 25.
NO :  Go to Step 2.

STEP 2. Measure the power supply voltage at cruise 
control switch connector C-201 by backprobing.
(1) Remove the cruise control switch from the steering wheel 

with the cruise control switch connector connected (Refer to 

P.17-65

).

(2) Connect the negative (

−) battery terminal that was 

disconnected when the driver's air bag module was 
removed.

(3) Do not disconnect cruise control switch connector C-201.
(4) Turn the ignition switch to the "ON" position.
(5) Do not operate the cruise control switch.
(6) Measure the power supply voltage between cruise control 

switch connector C-201 terminal number 3 and body 
ground by backprobing.

Q: Is the measured voltage between 4.7 and 5.0 volts?

YES : Go to Step 14.
NO :  Go to Step 3.

STEP 3. Measure the power supply voltage at ECM 
connector B-11.
(1) Disconnect all the connectors from the ECM [Refer to 

GROUP 13A, Engine Control Module (ECM) 

P.13A-887

] 

<2.4L Engine> or [Refer to GROUP 13B, Engine Control 
Module (ECM) 

P.13B-904

] <3.0L Engine>.

(2) Connect special tool MB992110 between the ECM and the 

body-side harness connector.

(3) Turn the ignition switch to the "ON" position.
(4) Do not operate the cruise control switch.

(5) Measure the power supply voltage between special tool 

48-pin connector terminal number 107 (ECM connector 
B-11 terminal number 107) and body ground.

Q: Is the measured voltage between 4.7 and 5.0 volts?

YES : Go to Step 10.
NO :  Go to Step 4.

STEP 4. Check ECM connector B-11 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector.
Refer to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Are the connector and terminals in good condition?

YES : Go to Step 5.
NO :  Repair or replace the damaged connector. Then go to 

Step 26.
