Symptom Chart

WARNING: This page is about a different car, the 2012 Land Rover Range Rover Sport and 2011 Land Rover Range Rover Sport. However, it is still accessible from the selected car via links, so may be relevant.
Symptom Possible Causes Action
Seat does not move when the switch is operated (forward, backward, tilt, etc.)
  • Runner or mechanism jammed
  • Seat circuit short circuit to ground, short circuit to power, open circuit, high resistance
  • Thermal cut-out engaged
  • Driver/Passenger Seat Module (DSM/PSM) fault
  • Check for obstructions at the seat runners or mechanisms
  • Refer to the electrical circuit diagrams and test the relevant seat circuit for short circuit to ground, short circuit to power, open circuit, high resistance
  • The thermal cut-out may engage if there is a motor or mechanism fault
  • Using the manufacturer approved diagnostic system, check the Driver/Passenger Seat Module (DSM/PSM) for related DTCs and refer to the relevant DTC index
Steering column does not move when the switch is operated
  • Steering column adjustment circuit short circuit to ground, short circuit to power, open circuit, high resistance
  • Central Junction Box (CJB) fault
  • Refer to the electrical circuit diagrams and test the steering column adjustment circuit for short circuit to ground, short circuit to power, open circuit, high resistance
  • Using the manufacturer approved diagnostic system, check the Central Junction Box (CJB) for related DTCs and refer to the relevant DTC index
Mirrors do not move when the switch is operated
  • Door mirror internal failure
  • Door mirror circuit short circuit to ground, short circuit to power, open circuit, high resistance
  • For door mirror tests, refer to the relevant workshop information.
  • Refer to the electrical circuit diagrams and test the door mirror circuits for short circuit to ground, short circuit to power, open circuit, high resistance
Memorized seat/steering column/mirror position is not resumed
  • Battery voltage below 10.5 volts
  • Position not stored
  • Switch operated during "one-touch" memory recall
  • Refer to the relevant workshop information and test the battery
  • Make sure that the desired position is correctly stored
  • Make sure that the memory store/recall procedure is being followed
"Lazy entry" function inoperative
  • Remote transmitter fault (battery, transmitter programming, etc.)
  • Battery voltage below 10.5V
  • Position not stored
  • Switch operated during "one-touch" memory recall
  • Check that the remote transmitter operates the central locking
  • Refer to the relevant workshop information and test the battery
  • Make sure that the desired position is correctly stored
  • Make sure that the memory store/recall procedure is being followed
Entry/Exit mode inoperative
  • Switch not in AUTO  mode
  • Driver/Passenger Seat Module (DSM/PSM) fault
  • Make sure the function is enabled and that the switch is correctly set
  • Using the manufacturer approved diagnostic system, check the Driver/Passenger Seat Module (DSM/PSM) for related DTCs and refer to the relevant DTC index
Seat does not get warm
  • Switch fault
  • Heated seat circuit short circuit to ground, short circuit to power, open circuit, high resistance
  • Temperature sensor
  • Battery voltage is greater than 16.5 volts
  • Check the LEDs at the switches as a quick check of the switch function. If the LEDs illuminate when the switches are operated, there is power to the switches and the switches are operating at least one level
  • Refer to the electrical circuit diagrams and test the heated seat circuit for short circuit to ground, short circuit to power, open circuit, high resistance
  • Test the operation of the temperature sensor
  • If the battery voltage is higher than 16.5 volts for more than 5 seconds, seat heating is suspended
Part of the seat does not get warm
  • Heated seat element fault
  • Refer to the electrical circuit diagrams and test the heated seat circuit for short circuit to ground, short circuit to power, open circuit, high resistance
