Read the instructions below then start the fault diagnostic procedure.
Symptom: Airbag warning lamp on.
| B0064, B0065, B0066 |
B0064 Driver pretensioner deployment circuit, resistance low.
B0065 Driver pretensioner deployment circuit, open circuit.
B0066 Driver pretensioner deployment circuit, voltage out of range.
Fault symptoms
Airbag warning lamp on.Conditions
B0064 The resistance measured by the control module falls below 1.5 ±0.2 Ω for 2 sB0065 The resistance measured by the control module exceeds 4.5 ±0.2 Ω for 2 s
B0066 Voltage on pin 34 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
Diagnostic help: The diagnostic tool can be used to read the amount of resistance in the ignition circuit.This project is supported by memberships and donations. If you use this site, please consider Joining SCNA and/or making a donation.
