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-tensioner 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 the negative and positive battery terminals, then wait at least three minutes.
3. Disconnect the harness connectors for the following SRS components. Refer to

• When installing diagnosis sensor unit bolt, use proper tightening sequence.

• Never damage the harness while installing.

• If malfunction is detected by the air bag warning lamp after repair or replacement of the malfunction-

ing parts, reset the memory using self-diagnosis or CONSULT. Refer to 

SRC-15, "Self-Diagnosis

Function (Without CONSULT)"

.

• After the work is completed, check that no system malfunction is detected by air bag warning lamp.

• 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.
