B1935 04, B2180 04

The seat heating control module does not detect a temperature change for up to 210 seconds.

B1935 0A, B2180 0A

The seat heating control module detects that the set point temperature has not been reached for up to 8.5 minutes.

B1935 0B, B1935 0E, B2180 0B, B2180 0E

By measuring the current and voltage output to the seat back heating element every 10 seconds, the seat heating control module calculates that the heating element resistance is below the minimum resistance value of 3.5 Ω.

B1935 0C, B1935 0D, B2180 0C, B2180 0D

By measuring the current and voltage output to the seat back heating element every 10 seconds, the seat heating control module calculates that the heating element resistance is above the maximum resistance value of 10 Ω.

B1935 1F, B2180 1F

The temperature sensor voltage is erratic or changes suddenly.
