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. |
| 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 power striker 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 power striker 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 power striker 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. |
