B100C-FLOOR MODE SWITCH REQUEST INPUT CIRCUIT PERFORMANCE

For a complete wiring diagram Consult Diagrams/Electrical.

Theory of Operation

The Floor mode switch input changes when the switch is pushed down. An active DTC indicates that the switch is stuck in a pushed position. A stored DTC indicates that the switch was stuck in a pushed position for more than two minutes, but has since returned to its normal state.

- When Monitored:
With the ignition on.

- Set Condition:
If the Floor mode switch is stuck in a pushed position for more than two minutes. This DTC has a maturing time of two minutes and a de-maturing time of two seconds. If the DTC's status changes from active to stored it will stay in memory for 100 ignition cycles.





Diagnostic Test

1. VERIFY THE DTC IS STILL ACTIVE
Inspect the A/C Heater Control for an object holding the switch in a pushed position. If present, remove the object.
Turn the ignition on.
With the scan tool, erase HVAC DTCs.
Turn the ignition off, wait 10 seconds, and then turn the ignition on. Wait 2 minutes before proceeding.
With the scan tool, read HVAC DTCs.
Does the scan tool display this DTC?

Yes

- Replace the A/C Heater Control.

Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
