Note :
The sensor is sensitive to shock acceleration against the housing and consequently against the sensor
element. Disturbances of this kind e.g. through hammer blows during body repairs are not permitted.
Ignition Off
• Open circuit in line between cables
• Disconnect 3-pin cable harness plug
from wiring harness and plug’s,terminal
from acceleration sensor.

• Excessive line and contact resistance
• Using multimeter, measure voltage
at plug contact.

Ignition Off
Ustab = 5V + 0.1V • Sensor defective; relace.
• Connect pin-out box between 3-pin
cable harness plug and sensor.
