REMOVAL

WARNING:

• Before servicing the SRS, turn ignition switch OFF, disconnect both battery terminals then wait at

least three minutes.

• Replace the air bag diagnosis sensor unit if any SRS air bag has been deployed or if any front seat

belt pre-tensioner has been deployed. 

• Before disconnecting the air bag diagnosis sensor unit harness connectors, be sure to disconnect

each harness connector of the front seat belt pre-tensioners (LH/RH) to prevent accidental air bag

deployment by static electricity and seat belt pre-tensioner operation.

• Do not use the air tools or electric tools for servicing.

• When replacing the air bag diagnosis sensor unit, always check with the parts department for the lat-

est parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the

air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags

and seat belt pre-tensioners in a collision resulting in serious personal injury or death.

1. Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) or part

number using CONSULT.

2. Disconnect negative and positive battery terminals, then wait at least three minutes. Refer to 

PG-69,

"Removal and Installation (Battery)"

.

3. Remove center pillar lower finisher. Refer to

• Do not damage the air bag diagnosis sensor unit harness or connectors during installation.

• After replacing the air bag diagnosis sensor unit, confirm using CONSULT that the ECU discrimi-

nated number (identification number) or part number of the new replacement air bag diagnosis sen-

sor unit matches the ECU discriminated number (identification number) or part number of the

replaced (old) air bag diagnosis sensor unit.

• After the work is completed, perform diagnosis to check that no malfunction is detected. Refer to

SRC-9, "Description"

.

NOTE:

If the ECU discriminated number or part number of the new replacement air bag diagnosis sensor unit differs

from the ECU discriminated number or part number of the replaced air bag diagnosis sensor unit, reconfirm

the parts information and verify that the correct air bag diagnosis sensor unit was installed.
