WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
- A1: CLIMATE SEATS ASSEMBLY - BLOWER SPEED CONTROL CIRCUIT RESISTANCE CHECKS AT SEAT TO VEHICLE CONNECTOR
- Uncouple connector IPO93 from the seat climate control module
- Check the resistance of the climate seats blower speed control circuits at connector IPO93
- For right-side seat cushion blower, check resistance at pins 3 and 7
- For right-side seat backrest blower, check resistance at pins 4 and 7
- For left-side seat cushion blower, check resistance at pins 11 and 15
- For left-side seat backrest blower, check resistance at pins 12 and 15
Is the resistance between 290 and 420 kilo-ohms?
- Yes : No circuit faults present. No further action
- No: GO to A2.
- A2: CLIMATE SEATS ASSEMBLY - BLOWER POWER CIRCUIT RESISTANCE CHECKS AT SEAT CLIMATE ASSEMBLY CONNECTOR
- Locate the appropriate seat backrest/seat cushion climate assembly connector
- Disconnect connector
- Check the integrity of connector terminals for bent terminals, backed-out or badly crimped wires. Rectify as required
- Check the resistance of the climate seats blower power circuits at the climate assembly connector, pins 2 and 4
Is the resistance between 290 and 420 kilo-ohms?
- Yes: GO to A3.
- No : Replace the seat climate assembly
- A3: CLIMATE SEATS ASSEMBLY - BLOWER SPEED CONTROL CIRCUIT RESISTANCE CHECKS AT SEAT CLIMATE ASSEMBLY CONNECTOR
- Check the resistance of the climate seats blower control circuits at the climate assembly connector, pins 4 and 7
Is the resistance between 290 and 420 kilo-ohms?
- Yes : No internal circuit faults present. Check for circuit faults in wiring harness between seat climate control module and climate seat assembly and replace as required
- No : Replace the seat climate assembly
