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

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Set  scan  tool  MB991958  to  the  coding  mode  for  VIN
Information.

(3)

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

Q:Has VIN (current) been written?

YES:

 Go to Step 2.

NO:

 Write VIN. Then go to Step 3.

STEP 2. Using scan tool MB991958, diagnose CAN bus line.

(1)

Turn the ignition switch to the "ON" position.

(2)

Diagnose CAN bus line.

(3)

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

Q:Is the CAN bus line normal?

YES:

 Go to Step 3.

NO:

 Repair the CAN bus line. Refer to GROUP 54D, Can Bus

Diagnostics Table P.54D-189. Then go to Step 4.

STEP 3. Using scan tool MB991958, read the immobilizer
diagnostic trouble code (DTC).

(1)

Turn the ignition switch to the "ON" position.

(2)

Read the immobilizer-DTC.

(3)

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

Q:Is the immobilizer-DTC set?

YES:

 Refer to GROUP 42B, Diagnosis - Diagnostic Trouble

Code Chart <Vehicles with KOS> P.42B-18or GROUP 42C,
diagnosis - Diagnostic Trouble Code Chart <Vehicles with
WCM> P.42C-11.

NO:

 Go to Step 4.

STEP 4. Using scan tool MB991958, read the diagnostic
trouble code (DTC)

(1)

Turn the ignition switch to the "ON" position.

(2)

After the DTC has been deleted, read the DTC again.

(3)

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

Q:Is DTC P0606 set?

YES:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration

CIRCUIT OPERATION

｠

A 5-volt voltage is supplied to the power steering
pressure  sensor  power  terminal  (terminal  No.  3)
from the ECM (terminal No. 43).

｠

The ground terminal (terminal No. 1) is grounded
with the ECM (terminal No. 59).

｠

A voltage that is proportional to the power steering
pressure is sent to the ECM (terminal No. 58) from
the power steering pressure sensor output terminal
(terminal No. 2).

TECHNICAL DESCRIPTION

｠

The  power  steering  pressure  sensor  outputs  a
voltage  which  corresponds  to  the  power  steering
pressure.

｠

The  ECM  checks  whether  this  voltage  is  within  a
specified range.

DESCRIPTIONS OF MONITOR METHODS
Power  steering  pressure  sensor  output  stays  high
during specified go/stop operations.
