REAR WIPER SWITCH OPEN
BODY CONTROL MODULE
TEST ACTION APPLICABILITY
1 Turn the ignition on.
With the DRB, select Body, Body Control Module and read the R Wiper Switch Sensor
voltage.
Does the DRB display a Switch voltage greater than 4.5 volts?All
Ye s®Go To 2
No®Go To 5
2 Turn the ignition off.
Disconnect the Rear Wiper Switch harness connector.
Connect a jumper wire between the Rear Wiper Switch MUX circuit and the Rear
Wiper Switch MUX Return circuit in the Rear Wiper Switch harness connector.
Turn the ignition on.
With the DRB, select Body, Body Controller and read the Rear Wiper SW volts.
Does the DRB R Wiper Switch Sensor voltage read less than 0.3 Volts?All
Ye s®Replace the Rear Wiper Switch in accordance with the Service
Information.
Perform BODY VERIFICATION TEST - VER 1.
No®Go To 3
3 Turn the ignition off to the lock position.
Disconnect the Body Control Module harness connector.
Disconnect the Rear Wiper Switch harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the Rear Wiper Switch MUX circuit from the Body Control
Module connector to the Rear Wiper Switch harness connector.
Is the resistance above 5.0 ohms?All
Ye s®Repair the Rear Wiper Switch MUX circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.

Ye s®Go To 2
No®Go To 6
2 Turn the ignition off.
Disconnect the Rear Wiper Switch harness connector.
Turn the ignition on.
With the DRB, select Body, Body Control Module and read the R Wiper Switch Sensor
voltage..
Does the DRB display more than 4.8 volts?All
Ye s®Replace the Rear Wiper Switch in accordance with the Service
Information.
Perform BODY VERIFICATION TEST - VER 1.
No®Go To 3
3 Turn the ignition off to the lock position.
Disconnect the Body Control Module harness connector.
Disconnect the Rear Wiper Switch harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between ground and the Rear Wiper Switch MUX circuit.
Is the resistance less than 5.0 ohms?All
Ye s®Repair the Rear Wiper Switch MUX Circuit for a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
