Test A: The Power Liftgate Is Inoperative - Does Not Open Or Close

PINPOINT TEST A: THE POWER LIFTGATE IS INOPERATIVE - DOES NOT OPEN OR CLOSE

Normal Operation
The power liftgate (PLG) module recieves battery voltage at all times through circuit SBP14 (BN/RD) and SBB29 (GY/RD). Ground is provided to the PLG module through circuit GD147 (BK/VT).

During power opening and/or power closing operation, the PLG module recieves inputs from the following system components:
- PLG control switch (instrument panel) or PLG close switch (quarter trim panel) through circuit CPR63 (GY/YE).
- Pinch strip through circuit CPR51 (YE/OG)(RH) and circuit CPR52 (YE/VT)(LH). The pinch strip switches are grounded through the PLG module through circuit RPR52 (VT/GY).
- Position sensor through circuit VPR53 (BU/WH) and VPR54 (BU/BN). The position sensor recieves 5 volts from the PLG module through circuit CPR55 (GN/BU) and ground from the PLG module through circuit RPR55 (WH/BU).
- Detent switch through circuit CPR66 (GY/YE).
- Forkbolt primary switch through circuit CPR64 (VT/OG).
- Forkbolt secondary switch through circuit CPR65 (BU/GN).
- Sector gear close switch through circuit CPR67 (VT).
- Sector gear open switch through circuit CPR68 (YE).

During power opening and/or power closing operation, the PLG module provides output to the following system components:
- PLG clutch through circuit CPR69 (BN/BU). Ground is provided to the clutch through circuit GD147 (BK/VT).
- PLG motor through circuit CPR57 (GN/WH) and circuit CPR58 (GN/OG).
- PLG cinch motor through circuit CPR61 (BN) and circuit CPR62 (WH/BU).
- PLG chime through circuit CPR56 (VT/BN) and circuit RPR56 (GY/VT).
