- Ignition OFF, disconnect the harness connector at the S82 windshield wiper/washer switch.
- With RAP OFF, MDI disconnected, wait one minute, test for less than 5 Ξ© between the low reference circuit terminal 2 and ground.
- If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K9 BCM.
- Ignition ON, test for B+ between the signal circuit terminal 1 and ground.
- If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
- Test for B+ between the signal circuit terminal 3 and ground.
- If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
- Test for 10 V between the signal circuit terminal 5 and ground.
- If less than the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
