(1)

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

(2)

Measure the voltage between terminal No. 104 and ground.

｠

Voltage should be battery positive voltage.

Q:Is  battery  positive  voltage  (approximately  12  volts)

present?

YES:

 Go to Step 4.

NO:

 Repair harness wire between battery and ECM connector

B-11 (terminal No. 104) because of open circuit or short
circuit to ground. Then go to Step 6.

STEP 4. Check harness connector B-11 at ECM for damage.

Q:Is the harness connector in good condition?

YES:

 Repair harness wire between battery and ECM

connector B-11 (terminal No. 104) because of harness
damage. Then go to Step 6.

NO:

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

Connector Inspection P.00E-2. Then go to Step 6.

STEP 5. Check harness connector B-11 at ECM for damage.

Q:Is the harness connector in good condition?

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 6.

NO:

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

Connector Inspection P.00E-2. Then go to Step 6.

DIAGNOSTIC TROUBLE CODE PROCEDURES

STEP 6. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

(1)

Turn the ignition switch to the "ON" position.

(2)

Read the DTC.

(3)

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

Q:Is DTC P1603 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.

DTC P1676: Variant Coding

M11310100395USA0000010000

TECHNICAL DESCRIPTION

｠

The ECM performs proper engine control based on
vehicle information entered.

｠

A vehicle identification number (VIN) is entered at
a  plant  before  shipment.  This  diagnosis  code
occurs  when  no  vehicle  information  is  entered
during ECM replacement.

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)

Turn the ignition switch to the "ON" position.

(3)

Read the A/T-DTC.

(4)

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

Q:Is DTC P1676 set?

YES:

 Replace the ECM with one into which vehicle

information is correctly entered.

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.

DTC P2066: Fuel Level Sensor (sub) Circuit Range/Performance

M11310100259USA0000010000

TECHNICAL DESCRIPTION

｠

The fuel level sensor convents the rest of the fuel to
a voltage and sends it to the combination meter.

｠

The  combination  meter  sends  the  data  regarding
the rest of the fuel to the ECM.

｠

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

DESCRIPTIONS OF MONITOR METHODS
Detect  malfunction  if  change  of  fuel  level  sensor
output voltage is small when sum of fuel injection is
large.
