DTC B1755

CIRCUIT DESCRIPTION
The seat adjuster switches are inputs to the driver seat module. The seat module supplies the adjuster switch assembly with a battery positive switch supply circuit and monitors the switch signal circuits. When a switch is pressed the signal circuit is closed to the switch power circuit within the adjuster switch assembly. When battery voltage is present on the switch signal circuit the seat module determines the switch status to be active.

CONDITIONS FOR RUNNING THE DTC
Battery voltage to the seat module must be within 8-17 volts.

CONDITIONS FOR SETTING THE DTC
A switch signal circuit to the seat module is active for more than 60 seconds.

ACTION TAKEN WHEN THE DTC SETS
