• Never 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.

.

• 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) of the new replacement air bag sensor unit matches the ECU
discriminated number (identification number) of the replaced (old) air bag diagnosis sensor unit.

NOTE:
If the ECU discriminated number of the new replacement air bag diagnosis sensor unit differs from the ECU
discriminated number of the replaced air bag diagnosis sensor unit, reconfirm the parts information and verify
