Circuit Description
When operation of the rear wiper is selected, battery voltage from the rear
wiper switch is applied to the rear wiper input of the body control module (BCM) circuit
94. The BCM responds by switching circuit 1445 to ground. This action energizes the
rear wiper relay, providing power to the rear wiper motor.
Conditions for Setting the DTC
| • | Ignition is in RUN or ACC position |
| • | Circuit 1445 is shorted to ground or open |
| • | Service (wrench) light will illuminate |
Diagnostic Aids
| • | Inspect wiring harness for damage. Check for broken or chaffed insulation. |
| • | If fault is suspected to be intermittent, wiggling harness wiring may
help in locating fault. |
| • | Check for poor connection at the BCM. Inspect harness connections for
backed out terminals, improper terminal mating, broken connectors locks, improperly
formed or damaged terminals and poor terminal-to-wire connection (terminal crimped
over wire insulation not conductors). |
| • | If circuit 1445 is open, no rear wipers. |
| • | If circuit 1445 shorted to ground, rear wipers are always on. |
