Data link

connector

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 (16-
pin).

2.

Read (and write down) all displayed diagnostic trouble codes
(Refer to P.52B-33).

NOTE:

If the battery power supply has been disconnected

or disrupted by the collision, scan tool MB991958 cannot
communicate with the SRS-ECU. Check the battery, then
check and, if necessary, repair the front wiring harness
and the instrument panel wiring harness before
proceeding.

3.

Read the data list (fault duration and how many times
memories are erased), using scan tool MB991958 (Refer
to P.52B-312).

4.

Erase the diagnostic trouble codes, and then turn the ignition
switch to the LOCK (OFF) position.

5.

Wait for at least one second, and then turn the ignition switch
to the ON position again.

6.

After waiting 15 seconds or more, note all displayed diagnostic
trouble codes (Refer to P.52B-31).

REPAIR PROCEDURE

WHEN FRONT AIR BAGS DEPLOY IN A COLLISION.

1.

Replace the following parts with new ones:

｠

SRS-ECU (Refer to P.52B-326).

｠

Air bag modules (Refer to P.52B-329).

｠

Seat belt with pre-tensioner (Refer to P.52B-345).

｠

Front impact sensors (Refer to P.52B-324).

｠

Front passenger’s air bag lid assembly (Refer to GROUP
52A, Instrument Panel Assembly P.52A-2).

2.

Check the following parts and replace if there are any
malfunctions:

｠

Clock spring (Refer to P.52B-329).

｠

Seat slide sensor (Refer to P.52B-349).

｠

Occupant classification-ECU and weight sensor.

｠

Seat belt switch (Refer to GROUP 52A, Front Seat
Assembly P.52A-18).

52B-316

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

POST-COLLISION DIAGNOSIS

｠

Steering wheel, steering column shaft assembly

(1)

Check the wiring harness (built into the steering wheel) and
connectors for damage, and terminals for deformation.

(2)

Install the air bag module to check fit and alignment with
the steering wheel.

(3)

Check the steering wheel for noise, binding or difficult
operation and excessive free play.

(4)

Check the steering column shaft shock absorbing
mechanism (Refer to GROUP 37A, On-Vehicle Service -
Steering Column Shaft Assembly Shock Absorbing
Mechanism Check P.37-19).

3.

Check the wiring harnesses for binding, the connectors for
damage, poor connections, and the terminals for deformation
(Refer to P.52B-28).

WHEN SIDE AIR BAGS DEPLOY IN A COLLISION.

1.

Replace the following parts with new ones:

｠

SRS-ECU (Refer to P.52B-326).

｠

Side impact sensors (Refer to P.52B-338).

｠

Front seatback assembly.

2.

Check the wiring harnesses for binding, the connectors for
damage, poor connections, and the terminals for deformation
(Refer to P.52B-28).

WHEN AIR BAGS DO NOT DEPLOY IN LOW-SPEED
COLLISION.
Check the SRS components. If the SRS components are
showing any visible damage such as dents, cracks, or
deformation, replace them with new ones. Concerning parts
removed for inspection, replacement with new parts and
cautionary points for working, refer to appropriate INDIVIDUAL
COMPONENT SERVICE P.52B-321.

FRONT IMPACT SENSOR

Front end upper bar

Front impact sensor

0001

1.

Check the front end upper bar for distortion and rust.

2.

Check the front impact sensor for dents, cracks, deformation
or rust.

3.

Check the front impact sensor wiring harness for binding,
check the connector for damage, and check the terminals for
deformation.

NOTE:

The illustration shows the side impact sensor (RH).

The position of the side impact sensor (LH) is symmetrical
to this.
