Pinpoint Test B : The Liftgate Unlatches But The Power Liftgate Is Inoperative: Notes
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Power Liftgate/Retractable Running Boards 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. |
| B1556:29 | Tailgate/Liftgate/Boot/Trunk Position Sensor 3: Signal Invalid | Sets when the RGTM receives no signal from the liftgate motor sensor 3 input or the sensor inputs are out of phase. |
| B1555:29 | Tailgate/Liftgate/Boot/Trunk Position Sensor 4: Signal Invalid | Sets when the RGTM receives no signal from the liftgate motor sensor 4 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 Left 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 Left power liftgate motor circuitry. |
| B144F:13 | Tailgate/Liftgate/Boot/Trunk Driver Motor: Circuit Open | Sets when the RGTM detects an open from the Left 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. |
| B1557:11 | Power Liftgate/Decklid Driver Motor 2: Circuit Short To Ground | Sets when the RGTM detects an open from the Right power liftgate motor circuitry. |
| B1557:12 | Power Liftgate/Decklid Driver Motor 2: Circuit Short To Battery | Sets when the RGTM detects an open from the Right power liftgate motor circuitry. |
| B1557:13 | Power Liftgate/Decklid Driver Motor 2: Circuit Open | Sets when the RGTM detects an open from the Right power liftgate motor circuitry. |
| B1515:97 | Tailgate/Liftgate/Boot/Trunk: Component or System Operation Obstructed or Blocked | Sets when the RGTM detects the power liftgate requires extra effort to open or the hydraulic strut does not keep the liftgate open. |
| B145D:11 | Tailgate/Liftgate/Boot/Trunk Power Cinch Striker Motor: Circuit Short To Ground | Sets when the RGTM detects a short to ground from one of the liftgate latch motor circuits. |
| B145D:12 | Tailgate/Liftgate/Boot/Trunk Power Cinch Striker Motor: Circuit Short To Battery | Sets when the RGTM detects a short to voltage from one of the liftgate latch motor circuits. |
| B145D:13 | Tailgate/Liftgate/Boot/Trunk Power Cinch Striker Motor: Circuit Open | Sets when the RGTM detects an open from one of the liftgate latch motor circuits. |
| 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. |
