ECU.

TROUBLESHOOTING HINTS

Malfunction of the SRS-ECU

DIAGNOSIS

Required Special Tool:

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

MB991824: Vehicle 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)

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 P.52B-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 54D,

Diagnosis P.54D-17).

(1)

Erase the DTC.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if the DTC is set.

(4)

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

Q:Is the DTC B223D set?

YES:

 Check the occupant classification-ECU. If no

abnormality is found, replace the SRS-ECU. (Refer to P.
52B-326).

NO:

 There is an intermittent malfunction such as poor

engaged connector(s) or open circuit (Refer to GROUP 00,
How to Cope with Intermittent Malfunction P.00-15).

DTC U0019: Bus Off (CAN-B)

M15204000971USA0000010000

If the DTC U0019 is set, be sure to diagnose the
CAN main bus line.

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

DIAGNOSTIC FUNCTION
If the CAN-B circuit malfunction occurs, the SRS-ECU
sets the DTC U0019.

JUDGMENT CRITERIA
Because of the CAN-B bus circuit malfunction, if SRS-
ECU  becomes  unable  to  perform  the  normal  data
transmission,  SRS-ECU  determines  that  an
abnormality is present.

TROUBLESHOOTING HINTS
The CAN bus line may be defective

DIAGNOSIS

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

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

(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:

 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.00-3).

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

(1)

Turn the ignition switch to the "ON" position.

(2)

Diagnose the CAN bus line.

(3)

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

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

YES:

 There is an intermittent malfunction such as poor

engaged connector(s) or open circuit (Refer to GROUP 00,
How to use Troubleshooting/inspection Service Points P.
00-15).

NO:

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

Diagnosis P.54D-17).

DTC U0141: ETACS CAN Timeout

M15204001003USA0000010000

If the DTC U0141 is set, be sure to diagnose the
CAN main bus line.

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

DIAGNOSTIC FUNCTION
If  the  signal  from  ETACS-ECU  cannot  be  received,
the SRS-ECU sets the DTC U0141.

JUDGMENT CRITERIA
Because of the CAN-B bus circuit malfunction, if SRS-
ECU  becomes  unable  to  perform  the  normal  data
transmission,  SRS-ECU  determines  that  an
abnormality is present.

TROUBLESHOOTING HINTS

The CAN bus line may be defective

The ETACS-ECU may be defective

The SRS-ECU may be defective
