REMOVAL

WARNING:

When replacing the air bag diagnosis sensor unit, always check with the parts department for he latest

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-tensioner in a collision resulting in serious personal injury or death.

CAUTION:

• Before servicing, turn ignition switch OFF, disconnect both battery terminals and wait at least three

minutes.

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

connector of each air bag module and pre-tensioner seat belt to prevent air bag deployment by static

electricity.

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

• Do not use old bolts after removal; replace with new bolts.

• Do not cause an impact to the diagnosis sensor unit by dropping etc. Replace the diagnosis sensor

unit if it has been dropped or sustained an impact.

• Replace the diagnosis sensor unit of deployed SRS air bag and deployed SRS front seat belt pre-ten-

sioner. 

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

number using CONSULT.

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

PG-63,

tions. Refer to 

SRC-13, "SRS Operation Check"

.

• 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.

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.
