Seat Heater Sensor: Testing and Inspection
For complete circuit diagrams, refer to Diagrams / Electrical.
NOTE: Any resistance values (ohms) given in the following text are supplied using the automatic range generated by a FLUKE© automotive meter. If
another type of measuring device is used the values generated may not be the same as the results shown here, or may have to be converted to the range
used here.
1. Backprobe the heated seat relay wire harness connector, do not disconnect. Using an voltmeter, check the voltage of the seat temperature sensor
input cavity of the heated seat relay wire harness connector. The seat sensor input voltage should be between 1.7 volts and 3.0 volts with the
system ON. If OK, sensor is OK at this time. If not OK, replace the faulty seat cushion heating element and sensor assembly.
