Checking the Resistance of the Detonation Circuit

Checking The Resistance Of The Detonation Circuit

Turn ignition switch to the OFF position.






Unplug the connector:
Seat-belt tensioner, right 236P







- Connect reference resistor 86 12 095 to the 2-pin female connector.







Unplug the connector:
Control module, Airbag 331







- Connect BOB to the wiring harness.







Take a resistance reading between
- 15 Control module, Airbag
- 45 Control module, Airbag







- Jiggle the leads and in-line connectors at several places and in different directions to reveal intermittent breaks and short circuits in the wiring harness. Observe the multimeter, test lamp or diagnostic tool while doing this.

The reading should be 2 - 4 Ohm


Is the function correct?

NO - Rectifying the Lead

YES - Changing Components
