For a complete Rear Spoiler Circuit Diagram, (Refer to 23 - BODY - SCHEMATICS AND DIAGRAMS).

Diagnostic Test

1.

REAR SPOILER LIMIT SWITCH SIGNAL (UP) CIRCUIT SHORT TO B(+)

Turn the ignition off.

Disconnect the BCM harness connector.

Disconnect the Rear Spoiler Limit Switch harness connector.

Note: Check connectors - Clean/repair as necessary.
Turn the ignition on.

Measure the voltage of the Rear Spoiler Limit Switch Signal (Up) cir-
cuit at the Rear Spoiler Limit Switch harness connector.

Is the voltage above 1.0 volts?

Yes

>> Repair the Rear Spoiler Limit Switch Signal (Up) circuit for

a short to B(+).

Perform REAR SPOILER VERIFICATION TEST.

No

>> Go to 2

2.

OPEN REAR SPOILER LIMIT SWITCH SIGNAL (UP) CIRCUIT

Turn the ignition off.

Measure the resistance of the Rear Spoiler Limit Switch Signal (Up)
circuit from the BCM C4 harness connector to the Rear Spoiler Limit
Switch harness connector.

Is the resistance below 5.0 ohms?

Yes

>> Go to 3

No

>> Repair the Rear Spoiler Limit Switch Signal (Up) circuit for

an open.

Perform REAR SPOILER VERIFICATION TEST.

3.

OPEN REAR SPOILER LIMIT SWITCH GROUND CIRCUIT

With the ignition off.

Measure the resistance between ground and the Rear Spoiler Limit
Switch Ground circuit at the Rear Spoiler Limit Switch harness con-
nector.

Is the resistance below 5.0 ohms?

Yes

>> Replace the Body Control Module.(Refer to 8 - ELECTRI-

CAL/ELECTRONIC CONTROL MODULES/BODY CON-
TROL/CENTRAL TIMER MODUL - REMOVAL).

Perform REAR SPOILER VERIFICATION TEST.

No

>> Repair the Rear Spoiler Limit Switch Ground circuit for an open.

Perform REAR SPOILER VERIFICATION TEST.
