Diagnostic Fault Information
Circuit/System Description
The liftgate control module (LGM) continuously monitors power liftgate operation and calculates its location and direction of travel using 2 Hall
effect sensors that are part of the gear motor assembly. The Hall effect sensors are 5-volt 3-wire sensors and are supplied with a 5-volt power,
ground and signal circuits from the LGM. The Hall effect sensor signal circuits are referenced from voltage within the LGM and pulsed low by the
Hall effect sensors.
Conditions for Running the DTC
The system voltage is 9-16 volts.
Conditions for Setting the DTC
B153E 02
The LGM detects a short to ground in the liftgate motor assembly position sensor circuit.
B153E 05
The LGM detects a short to voltage or an open/high resistance in the liftgate motor assembly position sensor circuit.
