SRS AIR BAG DIAGNOSIS

TSB Revision

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-339

STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the SRS-ECU.
(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 satellite radio tuner and the
ETACS-ECU. (Refer to GROUP 00, How to Cope with
Intermittent Malfunction

P.00-15

)

DTC U0212: Steering Wheel Sensor CAN Timeout

CAUTION

• If the DTC U0212 is set, be sure to diagnose

the CAN main bus line.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DTC SET CONDITION

If the signal from steering wheel sensor cannot be
received, the SRS-ECU sets the DTC U0212.

.

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

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)

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-340

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

P.52B-28

."

(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 steering
wheel sensor diagnostic trouble code
Check if the DTC is set to the steering wheel sensor.
Q: Is the DTC set?

YES : Diagnose the steering wheel sensor (Refer to

GROUP 35C, Diagnosis

P.35C-18

). then go to Step

3.

NO : Go to Step 3.

STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the SRS-ECU.
(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 : 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

).

DTC U1414: Defective Coding Data

CAUTION

• If the DTC U1414 is set, diagnose the CAN

main bus lines.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DTC SET CONDITION

If an incorrect information data is written in the
SRS-ECU, it sets DTC No. U1414.

.

JUDGMENT CRITERIA

When the coding data (vehicle information) from
ETACS-ECU is not received, SRS-ECU determines
that the abnormality is present.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective

• The ETACS-ECU may be defective

• The SRS-ECU may be defective

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

P.52B-28

."

(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 ETACS-ECU
diagnostic trouble code
Check if DTC Nos. U0331, B1761, B222C, B2206, or B2215 is
set to the ETACS-ECU.
Q: Is the DTC set?

YES : Diagnose the ETACS-ECU (Refer to GROUP 54A,

Diagnosis

P.54A-733

).

NO : Go to Step 3.

STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the SRS-ECU.
(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 : 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

).

DTC U1415: Coding not Completed/Data Fail

CAUTION

• If the DTC U1415 is set, diagnose the CAN

main bus lines.

• When replacing the ECU, always check that

the communication circuit is normal.

.

DTC SET CONDITION

If the vehicle information data is not registered to the
SRS-ECU, the SRS-ECU sets the DTC U1415.

.

JUDGMENT CRITERIA

With the global coding counter value "0", if all the glo-
bal coding data (vehicle information) are not stored,
the SRS-ECU determines that a problem has
occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective

• The ETACS-ECU may be defective

• The SRS-ECU may be defective
