B1035 Code - Crash Zone Sensor
Quick Answer
The Crash Zone Sensor is the main “G†sensor that generates a signal voltage when it detects deceleration beyond the specified level caused by a frontal vehicle collision. Common causes include Faulty Crash Zone Sensor, Crash Zone Sensor harness is open or shorted, Crash Zone Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B1035 Description
When the Air Bag Diagnosis Sensor Unit (ACU) defines both signal voltage of the “G†sensor and the safing sensor to be that of a collision which exceeds a specified level, the driving circuit switches on and feeds the electric ignitor of both driver and passenger air bags and pre-tensioner seat belt.
The Crash Zone Sensor has an integrated type of the “G†sensor element for frontal collision with output terminals for signal voltage.

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.
