DIAGNOSIS

Required Special Tools:

｠

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

｠

MB991824: V.C.I.

｠

MB991827: USB Cable

MB992110: Power Plant ECU Check Harness

STEP 1. Check harness connector B-106 at engine oil
pressure switch and harness connector B-10 at ECM for
damage.

Q:Is the harness connector in good condition?

YES:

 Go to Step 2.

NO:

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

Connector Inspection P.00E-2. Then go to Step 8.

STEP 2. Measure the power supply voltage at ECM
connector B-10 by using power plant ECU check harness
special tool MB992110.

Measure the voltage between terminal No. 7 and ground.

｠

Voltage should be 1 volt or less when engine is idling.

｠

Voltage  should  be  battery  positive  voltage  when  engine
speed is higher than 5,200 r/min.

(4)

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

Q:Is the measured voltage normal?

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 Malfunctions P.00-15.

NO:

 Go to Step 3.

STEP 3. Measure the power supply voltage at engine oil
pressure switch connector B-107.

(1)

Disconnect the connector B-107 and measure at the harness
side.

(2)

Turn the ignition switch to the "ON" position.

Q:Is  battery  positive  voltage  (approximately  12  volts)

present?

YES:

 Go to Step 5.

NO:

 Go to Step 4.

STEP 4. Check for open circuit and short circuit to ground
between engine oil pressure switch connector B-107 and
ECM connector B-10.
