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. Refer to "How to connect the
Scan Tool (M.U.T.-III) P.54Ab-5."

(2)

Turn the ignition switch to the "ON" position.

(3)

Diagnose the CAN bus line.

(4)

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

Q:Is the CAN bus line found to be normal?

YES:

 Go to Step 2.

NO:

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

Diagnosis P.54D-17).

STEP 2. Using scan tool MB991958, read the SRS-ECU
diagnostic trouble code
Check again if the DTC is set to the SRS-ECU.

Q:Is the DTC set?

YES:

 Troubleshoot the SRS (Refer to GROUP 52B,

Troubleshooting P.52B-33).

NO:

 Go to Step 3.

STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the combination meter.

(1)

Erase the DTC.

(2)

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

(3)

Check if DTC is set.

(4)

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

Q:Is the DTC set?

YES:

 Replace the combination meter.

NO:

 The trouble can be an intermittent malfunction (Refer

to GROUP 00 - How to use Troubleshooting/inspection
Service Points - How to Cope with Intermittent
Malfunction P.00-15).

DTC U0154: Occupant classification-ECU CAN timeout

M15410100105USA0000010000

｠

If DTC U0154 is set, be sure to diagnose the CAN
bus line.

｠

When replacing the ECU, always check that the
communication circuit is normal.

COMBINATION METER

54Ab-29

DIAGNOSIS

DIAGNOSTIC FUNCTION
When  the  signals  from  occupant  classification-ECU
cannot be received, the combination meter sets DTC
U0154.

JUDGMENT CRITERIA
With  the  ignition  switch  in  the  ON  position,  system
voltage  between  10  -  16  volts  (data  from  ETACS-
ECU), power supply fuse is OK, or odometer value is

80.5 km (50 miles) or more, and the communications
with  occupant  classification-ECU  cannot  be
established  for  2,500  ms  or  more,  the  combination
meter determines that a problem has occurred.

TROUBLESHOOTING HINTS

｠

The CAN bus line may be defective.

｠

The combination meter may be defective.

｠

The occupant classification-ECU may be defective.
