4-Way Lumbar and Bolster - Memory 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 inoperative	Seat switchpack internal failure 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. GO to PINPOINT TEST B .
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. 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 .
