Unable to receive ETACS-ECU signals through the
CAN bus line for 4 seconds.

COMMENT

Current Trouble

｠

Some of the possible causes are a harness or
connector damage between the ECM and the
ETACS-ECU on the CAN bus line, a failure in the
ETACS-ECU power supply system, a failure in the
ETACS-ECU, or a failure in the ECM.

Past Trouble

｠

Proceed to troubleshoot based on a harness or
connector damage on the CAN bus line between
the ECM and ETACS-ECU, and a failure in the
ETACS power supply system. Refer to "How to
cope with past trouble" (Refer to GROUP 00, How
to Use Troubleshooting/Inspection Service Points -
How to Cope with Intermittent Malfunctions P.
00-15).

DIAGNOSTIC TROUBLE CODE PROCEDURES

When the ignition key is maintained within the
range "A" (i.e., the ignition switch IG2 is in OFF
position but the cranking does not start) for more
than 1 second, ECM stores DTC U0141 (the past
trouble).

NOTE:

If a malfunction occurred in the past, a

failure cannot be discovered through the MB991958
CAN bus diagnosis even if there might be a problem
with the CAN bus. In this case, refer to GROUP
00,How to Use Troubleshooting/Inspection Service
Points - How to Cope with Intermittent
Malfunctions P.00-15. Furthermore, it is possible

to narrow down the areas of the possible failures
from the DTCs that are output by the ECUs, which
are communicating on the CAN bus (Refer to GROUP
54D, CAN bus line Diagnostics Flow P.54D-10).

OBD-II DRIVE CYCLE PATTERN
None.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)

｠

CAN line harness damage or connector damage.

DIAGNOSIS

Required Special Tools:

｠

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

｠

MB991824: V.C.I.

｠

MB991827: USB Cable

｠

MB991910: Main Harness A

STEP 1. Using scan tool MB991958, diagnose CAN bus line.

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)

Diagnose CAN bus line.

(4)

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

Q:Is the CAN bus line 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:

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

Diagnostics Table P.54D-10. Then go to Step 2.

STEP 2. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

(1)

Erase the DTC.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if DTC is set.

(4)

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

Q:Is DTC U0141 set?

YES:

Retry the troubleshooting.

DTC U0167: KOS-ECU/WCM Communication Error

M11310100402USA0000010000

｠

If the ECM output the DTC U0167, make sure to
diagnose the CAN bus line.

｠

Before replacing the ECU, make sure that the
communication circuit is operating normally.

Unable to receive KOS-ECU/WCM (immobilizer-
ECU) signals through the CAN bus line.

COMMENT

Current Trouble

｠

Some of the possible causes are a harness or
connector damage between the ECM and the KOS-
ECU/WCM on the CAN bus line, a failure in the
