Diagnostic Fault Information
Circuit/System Description
When the heated seat function is active, the rear heated seat module (RHSM) supplies battery voltage through the element supply voltage circuit to
the seat heater elements. The RHSM 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 RHSM 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 RHSM must be powered and the heated seat must be enabled.
Conditions for Setting the DTC
B2425 04 or B2430 04
The RHSM does not detect a temperature change within 210 seconds.
B2425 0A or B2430 0A
The RHSM detects that the set point temperature has not been reached within 8.5 minutes.
B2425 0B, B2425 0E, B2430 0B, or B2430 0E
