Check Conditions

｠

Battery positive voltage is between 11 and 16.5
volts.

｠

2 seconds or more have passed since the engine
staring sequence was completed.

MB991827: USB Cable

｠

MB991910: Main Harness A

STEP 1. Check fuel gauge.

Q:Is the fuel gauge functioning?

YES:

Go to Step 2.

NO:

Refer to GROUP 54A, Chassis Electrical - Combination

Meters Assembly - Symptom Chart P.54Ab-40.

STEP 2. Check the trouble symptoms.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0463 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 3.

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 3. Test 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 24 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0463 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

CIRCUIT OPERATION

｠

The EGR valve power is supplied from the MFI relay
(terminal No. 2).

｠

The ECM (terminals No. 31, No. 32, No. 47, No. 48)
drives the stepper motor by sequentially turning
"ON" the power transistors in the ECM and
providing ground to the EGR valve (terminal No. 1,
No. 3, No. 4, No. 6).

TECHNICAL DESCRIPTION
The ECM checks whether a short circuit to the ground
or an open circuit exists or not by measuring the EGR
valve (stepper motor) drive circuit voltage when the
current is not flowing through the coils of the EGR
valve (stepper motor).

DESCRIPTIONS OF MONITOR METHODS
When the EGR valve (stepper motor) drive circuit
voltage is under the specified range, it is judged that
a malfunction exists.
