PRECAUTIONS BEFORE SERVICE

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

M1001011600056

1. Items to review when servicing SRS:

(1) Be sure to read GROUP 52B, Supplemental

Restraint System (SRS). For safe operation,
please follow the directions and heed all
warnings.

(2) Wait at least 60 seconds after disconnecting

the battery cable before doing any further
work. The SRS system is designed to retain
enough voltage to deploy the air bag even
after the battery has been disconnected.
Serious injury may result from unintended air
bag deployment if work is done on the SRS
system immediately after the battery cable is
disconnected.

(3) Warning labels must be heeded when

servicing or handling SRS components.
Warning labels can be found in the following
locations.
• Front impact sensor
• Hood
• Sun visor
• Instrument panel (passenger’s side)
• SRS-ECU
• Steering wheel
• Clock spring
• Air bag module (Driver's or front
passenger's)
• Side-airbag module (Driver's side or front
passenger's side)
• Side impact sensor
• Seat belt pre-tensioner

(4) Always use the designated special tools and

test equipment.

(5) Store components removed from the SRS in a

clean and dry place. The air bag module
should be stored on a flat surface and placed
so that the pad surface is facing upward.

(6) Never attempt to disassemble or repair the

SRS components (SRS-ECU, air bag module
and clock spring). If there is a defect, replace
the defective part.

(7) Whenever you finish servicing the SRS, check

the SRS warning light operation to make sure
that the system functions properly.

(8) Be sure to deploy the air bag before disposing

of the air bag module or disposing of a vehicle
equipped with an air bag (Refer to GROUP
52B, Air Bag Module Disposal Procedures

P.52B-254

).

2. Observe the following when carrying out

operations on places where SRS components are
installed, including operations not directly related
to the SRS air bag.
(1) When removing or installing parts, do not allow

any impact or shock to occur to the SRS
components.

(2) If heat damage may occur during paint work,

remove the SRS-ECU, the air bag module,
clock spring, the front impact sensor, the side
impact sensor, and the seat belt pre-tensioner.
a. SRS-ECU, air bag module, clock spring,

front impact sensor, the side impact sensor:
93

°C (200°F) or more

b. Seat belt pre-tensioner: 90

°C (194°F) or

the vehicle manufacture. If the VIN to be stored in the ECU is
eliminated fraudulently, the Malfunction Indicator Lamp (Check
Engine Lamp) illuminates and Diagnostic Trouble Code (DTC)
No.P0630 (VIN malfunction) is shown. When the ECU is
replaced, and entry of the VIN necessary due to DTC No.
P0630 (VIN malfunction). Enter the VIN in accordance with the
procedure as follows:

.

WRITING PROCEDURE

Required Special Tools:

• Diagnostic Tool (MUT-III)

• MB991824: V.C.I.

• MB991827: MUT-III USB Cable

• MB991910: MUT-III Main Harness A (BLUE)

CAUTION

To prevent damage to DIAGNOSTIC TOOL (MUT-III), always
turn the ignition switch to the "LOCK" (OFF) position
before connecting or disconnecting.
1. Connect Diagnostic Tool to the data link connector.

2. Turn the ignition switch to the "ON" position.

3. Confirm DTC No.P0630 (EEPROM malfunction) is not
