What does this fault code mean?
The control module has found a fault in the heater pad of the right seat heater. The control module talks to the right-hand seat heating module over an internal bus. The fault is probably an open circuit, or a short to supply voltage or ground, in the wiring between the module and the heater pad. The right front seat heater then cannot be activated.
Possible causes
- Open circuit in the wire running from the seat heating module and the heater pad
- Cable linking the seat heating module to the heater pad shorted to live voltage
- Cable linking the seat heating module to the heater pad shorted to ground
What you can do
- 1With the ignition on, check the connectors at the seat heating module and the heater pad for contact resistance, oxidation and loose contacts
- 2Check the heating wires in the seat and backrest for damage. With the ignition off, use a multimeter to check whether the wire touches ground (the body) or live voltage
- 3Remedy anything found and clear the fault code
- 4Have a workshop carry out the other measurements on the seat heater circuit and replace the heater pad if it is defective
- 5If you have a diagnostic tool, activate the seat heater from the activation function and check that the seat gets warm
Symptoms you may notice1
- The front seat heating does not work
What the fault can affect1
- The control module does not allow the seat heater to be switched on
