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
).
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to data reading mode for cruise
control system (Refer to
).
• 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
(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)
<2.4L Engine> or [Refer to GROUP 13B, Engine Control
Module (ECM)
] <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
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.
