B0022, B0024, B0026


B0022 Driver frontal deployment circuit (stage 1), resistance low.

B0024 Driver frontal deployment circuit (stage 1), voltage out of range.

B0026 Driver frontal deployment circuit (stage 1), open circuit.


Fault symptom

Airbag warning lamp on.

Conditions

Ignition on

Fault criteria

B0022 The resistance measured by the control module falls below 2.0 ±0.2 Ω for 2 s

B0026 The resistance measured by the control module exceeds 4.5 ±0.2 Ω for 2 s

B0024 Voltage on pin 28 in the control module exceeds 4.1 ±0.15 V or falls below 1.0 ±0.15 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.
