Code B1062 Description

Detects the whole SRS electrical system and displays the malfunction either by illuminating or blinking the airbag warning lamp in the combination meter. Malfunctioning part can be detected by the on-board self-diagnosis system. It detects a shock that exceeds specified level and monitors such systems as the driver and passenger airbag, side airbag, curtain airbag, pre-tensioner seat belts and Occupant Classification System (OCS) operate properly. It contains the G sensors for both frontal and side collisions and spare battery function in case of main battery damage in the collision. The OBDII code sets when the airbag diagnosis sensor unit is out of order or mismatch

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
