For cushion side of seat warmer, check for continuity and measure the resistance between No.2 terminal of control unit harness connector and No.1 terminal of cushion connector.
For back side of seat warmer, check for continuity and measure the resistance between No.1 and No.2 terminal of back connector.
Standard value
Cushion : 1.43Ω ± 10%, Back : 1.01Ω ± 10%
Operate the seat warmer after connecting the connectors, and then check the NTC(Negative Temperature Coefficient) thermostat by measuring the temperature of seat surface.
