Circuit/System Description
When the heated seat function is active, the heated seat module (HSM) supplies battery voltage through the element supply voltage circuit to the
seat heater elements. The HSM controls the seat temperature by providing a pulse width modulated (PWM) ground through the heated seat element
control circuit to the seat heater elements. The HSM then monitors the current flow through the heating element and the temperature sensor rate of
change to verify correct operation.
Conditions for Running the DTC
The HSM must be powered and the heated seat must be enabled.
Conditions for Setting the DTC
B2425 04 or B2430 04
The HSM does not detect a temperature change within 210 seconds.
B2425 0A or B2430 0A
The HSM detects that the set point temperature has not been reached within 8.5 minutes.
B2425 0B, B2425 0E, B2430 0B, or B2430 0E
By measuring output current, the HSM calculates that the heating element resistance is below the minimum resistance.
B2425 0C, B2445 0D, B2430 0C, or B2430 0D
By measuring output current, the HSM calculates that the heating element resistance is above the maximum resistance.
B2425 1F or B2430 1F
The temperature sensor voltage is erratic or changes suddenly.
