Checking the contact reel

Checking components and wiring
Disconnect the contact reel from the steering wheel module (SWM).
Take resistance readings between terminals #B1 and #B2. The resistance must be infinite.
Take resistance readings between terminals #B1 and #B3. The resistance must be infinite.
Take resistance readings between terminals #B2 and #B3. The resistance must be infinite.
Check the cable between terminal #B1 and contact reel terminal #1. Check for an open-circuit.
Check the cable between terminal #B2 and contact reel terminal #2. Check for an open-circuit.
Check the cable between terminal #B3 and contact reel terminal #3. Check for an open-circuit.
Remedy as necessary.
