CIRCUIT OPERATION

｠

The battery voltage is applied from the MFI relay to
the  radiator  sensor  (terminal  No.  3),  and  it  is
grounded  to  the  vehicle  body  from  the  radiator
sensor (terminal No. 1).

｠

The  radiator  sensor  (terminal  No.  2)  sends  the
sensor signal to the ECM (terminal No. 99).

TECHNICAL DESCRIPTION

｠

The ECM judges the tampering of the DOR radiator
according to the signal from the radiator sensor.

MONITOR EXECUTION

｠

｠

MB991910: Main Harness A

STEP 1. Measure the battery positive voltage.

(1)

Measure the battery positive voltage during cranking.

｠

The voltage should remain greater than 8 volts while the
engine is cranked.

Q:Does  the  voltage  remain  greater  than  8  volts  while  the

engine is cranked?

YES:

 Go to Step 2.

NO:

 Refer to GROUP 54A, Battery - Battery check P.

54Aa-2.

STEP. 2 Check harness connector A-48 at radiator sensor
and harness connector B-11 at ECM for damage.

Q:Is the harness connector in good condition?

YES:

 Go to Step 3.

NO:

 Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection P.00E-2. Then go to Step 7.

STEP 3. Measure the supply voltage at radiator sensor
connector A-48.

(1)

Disconnect radiator sensor harness connector A-48.

(2)

Turn the ignition switch to the "ON" position.

(3)

Measure  the  voltage  between  harness  connector  A-48
(terminal No. 3) and ground.

｠

The voltage should equal battery positive voltage.

(4)

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

Q:Is the measured voltage battery positive voltage?

YES:

 Go to Step 4.

NO:

 Repair harness wire between MFI relay connector A-33X

(terminal No. 2) and radiator sensor connector A-48
(terminal No. 3) because of harness damage. Then go to
Step 7.

STEP 4. Check for open circuit or harness damage between
radiator sensor connector A-48 and ground.

(1)

Disconnect the connector A-48 measure at the harness side.

(2)

Measure  the  resistance  between  connector  A-48  (terminal
No. 1) and ground.

｠

Should be less than 2 ohms.

Q:Is the measured resistance less than 2 ohms?

YES:

 Go to Step 5.

NO:

 Repair it. Then go to Step 7.

STEP 5. Check for short circuit to ground or open circuit
between radiator sensor connector A-48 and ECM
connector B-11.

(1)

Disconnect  the  connector  A-48  and  B-11  measure  at  the
harness side.

(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)

Read the DTC.

(5)

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

Q:Is DTC P1540 or P1541 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 7.

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.
