4-Way Lumbar, Bolster and Massage - Front Seats

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure.

SYMPTOM	POSSIBLE CAUSES	ACTION
All seat functions inoperative	Seat system fault Seat switchpack power or ground circuit open circuit, high resistance Seat switchpack internal failure	GO to PINPOINT TEST A .
Lumbar forward/up/down AND bolster inflate AND massage functions inoperative	Seat switchpack internal failure Master massage solenoid power or ground circuit open circuit, high resistance Lumbar air pump circuit short circuit to ground, short circuit to power, open circuit, high resistance Air hose blocked Air hose leaking Relief valve stuck open	NOTE: Lumbar/massage air pump operation will be inhibited if the motor temperature exceeds 72±4°C (162±7°F). The lumbar/massage air pump will not re-start until 10 minutes after the temperature has decreased below the cut-off temperature. This condition is not a fault. The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. Using the Jaguar Land Rover approved diagnostic equipment, perform routine - On Demand Self Test. Check the relevant seat module for related DTCs and refer to the relevant DTC index
Lumbar forward inoperative	Seat switchpack internal failure Lumbar solenoid circuit short circuit to ground, short circuit to power, open circuit, high resistance Air hose blocked Air hose leaking Air cell leaking	NOTE: The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. GO to PINPOINT TEST C .
Lumbar rearward inoperative	Seat switchpack internal failure Lumbar solenoid circuit short circuit to ground, short circuit to power, open circuit, high resistance Air hose blocked	NOTE: The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. GO to PINPOINT TEST D .
Lumbar up inoperative	Seat switchpack internal failure Lumbar solenoid circuit short circuit to ground, short circuit to power, open circuit, high resistance Air hose blocked Air hose leaking Air cell leaking	NOTE: The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. GO to PINPOINT TEST E .
Lumbar down inoperative	Seat switchpack internal failure Lumbar solenoid circuit short circuit to ground, short circuit to power, open circuit, high resistance Air hose blocked Air hose leaking Air cell leaking	NOTE: The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. GO to PINPOINT TEST F .
Bolster inflate inoperative	Seat switchpack internal failure Lumbar air pump circuit short circuit to ground, short circuit to power, open circuit, high resistance Air hoses blocked/leaking Air cells leaking	NOTE: The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. GO to PINPOINT TEST I .
Bolster deflate inoperative	Seat switchpack internal failure Bolster solenoid circuit short circuit to ground, short circuit to power, open circuit, high resistance Air hoses blocked	NOTE: The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. GO to PINPOINT TEST J .
Seat massage functions inoperative (all seats)	Incorrect power mode Vehicle interior temperature too high/low	NOTE: The engine must be running and the vehicle interior temperature must be between 0°C (32°F) and 50°C (122°F) for the seat massage functions to operate. Start the engine and retest Cool or warm the vehicle interior as necessary and retest
Seat massage functions inoperative (one seat only)	Lumbar/massage air pump thermal protection active LIN bus Massage master solenoid Massage slave solenoid Air hose blocked Air hose leaking Air cell leaking	NOTE: Lumbar/massage air pump operation will be inhibited if the motor temperature exceeds 72±4°C (162±7°F). The lumbar/massage air pump will not re-start until 10 minutes after the temperature has decreased below the cut-off temperature. The Lumbar/Massage solenoid block is installed with an air exhaust valve that is designed to expel air under operating conditions. This is not an air leak and does not represent a solenoid block failure. GO to PINPOINT TEST K .
Seat massage functions will not operate indefinitely	Massage seat functions cease when the timed cycle is complete	NOTE: The seat massage cycle lasts approximately 10 minutes. Operate the massage seat switches again to repeat the cycle
Seat massage uncommanded operation	Auto massage function active	NOTE: The auto massage function allows seat massage to commence automatically after a preset time (5, 15, 30 or 60 minutes). Set the auto massage function to off as necessary
