For a complete wiring diagram, refer to.

• When Monitored: With the ignition ON.

• Set Condition: When the totally integrated power module TIPM detects a short/low condition on the rear wiper motor control circuit.






Test Step 1 - Intermittent Condition

• Turn the ignition ON.

• With the scan tool, clear all TIPM DTCs.

• Turn the Washers ON.

• With the Scan Tool, read the Wiper/Washers DTCs.

Does the scan tool display B2376 - Rear Wiper Switch Input Circuit?

Yes

• Go to Test Step 2.

No

• The condition that caused this symptom is currently not present. Test for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
