Check Condition

｠

Battery positive voltage is higher than 11 volts.

｠

Intake air temperature is between 0°C (32°F) to 40°
C (104°F) when the engine is started.

｠

Engine coolant temperature is between 0°C (32°F)
to 40°C (104°F) when the engine is started.

｠

Judgement Criteria

｠

When the output temperature of the radiator sensor
before the thermostat valve is opened is high, the
sensor is defective.

(1)

Replace the DOR radiator.

To prevent damage to scan tool MB991958, always turn
the ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(2)

Connect scan tool MB991958 to the data link connector.

(3)

Turn the ignition switch to the "ON" position.

(4)

(5)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is DTC P1544 set?

YES:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 4.

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 Malfunctions P.00-15.

STEP 4. Perform the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic  Function  -  OBD-II  Drive  Cycle  -  Pattern  19  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P1544 set?

YES:

 Repeat the troubleshooting.
