Pinpoint Test B : The Liftgate Unlatches But The Power Liftgate Is Inoperative: Notes
WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Power Liftgate for schematic and connector information.
Normal Operation and Fault Conditions
REFER to: Body Closures - System Operation and Component Description .
RGTM DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B144D:29 | Tailgate/Liftgate/Boot/Trunk Position Sensor 1: Signal Invalid | Sets when the RGTM receives no signal from the liftgate motor sensor 1 input or the sensor inputs are out of phase. |
| B144E:29 | Tailgate/Liftgate/Boot/Trunk Position Sensor 2: Signal Invalid | Sets when the RGTM receives no signal from the liftgate motor sensor 2 input or the sensor inputs are out of phase. |
| B144F:11 | Tailgate/Liftgate/Boot/Trunk Driver Motor: Circuit Short To Ground | Sets when the RGTM detects a short to ground from the power liftgate motor circuitry. |
| B144F:12 | Tailgate/Liftgate/Boot/Trunk Driver Motor: Circuit Short To Battery | Sets when the RGTM detects a short to voltage from the power liftgate motor circuitry. |
| B144F:13 | Tailgate/Liftgate/Boot/Trunk Driver Motor: Circuit Open | Sets when the RGTM detects an open from the power liftgate motor circuitry. |
| B144F:79 | Tailgate/Liftgate/Boot/Trunk Driver Motor: Mechanical Linkage Failure | Sets when the RGTM detects the power liftgate requires extra effort to open or the hydraulic strut does not keep the liftgate open. |
| B1A59:11 | Sensor 5 Volt Supply: Circuit Short To Ground | Sets when the RGTM detects a short to ground from the power liftgate motor sensor voltage supply circuit. |
| B1A59:13 | Sensor 5 Volt Supply: Circuit Open | Sets when the RGTM detects an open from the power liftgate motor sensor circuitry. |
