B0014

B0012, B0013, B0014

B0012 Passenger frontal deployment circuit(stage 2) resistance low

B0013 Passenger frontal deployment circuit (stage 2) open

B0014 Passenger frontal deployment circuit (stage 2) voltage out of range







Fault symptom
Airbag warning lamp on.

Conditions
Ignition on

Fault criteria
B0012 The resistance measured by the control module falls below 1.5 ± 0.2 ohms for 2 s
B0013 The resistance measured by the control module exceeds 4.5 ± 0.2 ohms for 2 s
B0014 Voltage on pin 42 in the control module exceeds 4.1 V or falls below 1.0 V for 2 s.

System reaction to a fault
Even if there is a fault in the ignition circuit, the control module will try to trigger the airbag in the event of a collision.

Diagnostic help
The diagnostic tool can be used to read the amount of resistance in the ignition circuit.
