STEP 4. 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 SRS-ECU.
NO : The trouble can be an intermittent malfunction such

as a poor connection or open circuit in the CAN bus
lines between the SRS-ECU and the combination
meter (Refer to GROUP 00, How to Cope with
Intermittent Malfunction

DTC U0154: Occupant classification-ECU CAN timeout

CAUTION

• 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.

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 (IOD fuse) is OK,
or odometer value is 80.5 km (50 miles) or more, and
the communications with occupant classifica-
tion-ECU cannot be established for 2,500 ms or
more, the combination meter determines that a prob-
lem has occurred.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective.

• The combination meter may be defective.

• The occupant classification-ECU may be defec-

tive.

DIAGNOSIS

Required Special Tools:

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

• MB991824: Vehicles Communication Interface (V.C.I.)

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A (Vehicles with

CAN communication system)

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

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect the

Scan Tool (M.U.T.-III)

P.54A-31

(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 54C,

Diagnosis

P.54C-17

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

YES : Troubleshoot the SRS. (Refer to GROUP 52B,

Diagnosis

P.52B-344

NO : Go to Step 3.

STEP 3. Using scan tool MB991958, read the A/C-ECU
diagnostic trouble code.
Check if the DTC U0154 is set to the A/C-ECU.
Q: Is the DTC set?

YES : Go to Step 4.
NO : Go to Step 5.

DTC U0164: A/C-ECU CAN timeout

CAUTION

• If DTC U0164 is set, be sure to diagnose the

CAN bus line.

• When replacing the ECU, always check that

the communication circuit is normal.
