B0057

B0057, B0058, B0059

B0057 Passenger pretensioner deployment circuit, resistance low.

B0058 Passenger pretensioner deployment circuit, open circuit.

B0059 Passenger pretensioner deployment circuit, voltage out of range.










Fault symptoms
Airbag warning lamp on.

Conditions
B0057 The resistance measured by the control module falls below 1.5 ± 0.2 ohms for 2 s
B0058 The resistance measured by the control module exceeds 4.5 ± 0.2 ohms for 2 s
B0059 Voltage on pin 37 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 seat-belt tensioner in the event of a collision.

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