Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
-
Listen for an audible click when the park relay operates. Command both the ON and OFF states. Repeat the commands as necessary. An audible click indicates that the coil side of the relay is operating.
-
Tests for voltage at the coil side of the park relay.
-
Verifies that the Rear Integration Module (RIM) is providing ground to the park relay.
-
Tests if ground is constantly being applied to the park relay.
-
Tests for voltage at the switch side feed circuit of the park relay. The Reverse Lockout Fuse supplies power to the switch side feed circuit of the park relay.
