Steering Pad Switch Circuit: Description

WARNING: This page is about a different variant/trim than selected.

AUTO, OFF, TEMP UP (+), and TEMP DOWN (-) switches are located on the steering pad switch. The resistance of the steering pad switch changes in accordance with switch operation. The air conditioning control assembly outputs voltage to the steering pad switch and reads voltage changes due to the resistance changes that result from switch operation.

HINT:

If there is an open in the circuit, the air conditioning system cannot be operated by the steering pad switch assembly.

If there is a short in the circuit, the resulting condition is the same as if the switch were continuously depressed. Therefore, the air conditioning control assembly cannot be operated by the steering pad switch assembly, and the air conditioning control assembly will not be able to function correctly.
