Conditions for Setting the DTC
B2425 04, B2430 04
The module does not detect a temperature change for up to 210 seconds.
B2425 0A, B2430 0A
The module detects that the set point temperature has not been reached for up to 8.5 minutes.
B2425 0B, B2425 0E, B2430 0B, B2430 0E
By measuring the current and voltage through the seat cushion heating element every 10 seconds, the seat memory control module calculates that the heating element resistance is below the minimum resistance.
B2425 0C, B2425 0D, B2430 0C, B2430 0D
By measuring the current and voltage through the seat cushion heating element every 10 seconds, the seat memory control module calculates that the heating element resistance is above the maximum resistance.
B2425 1F, B2430 1F
The temperature sensor voltage is erratic or change suddenly.
