Diagnostic Test


1. TEST FOR INTERMITTENT CONDITION
Turn the ignition On.
With the scan tool, erase all DTC's.
Operate the Folding Seat Select Switch several times.
With the scan tool, read DTC's.
Does the scan tool display this DTC?

Yes


- Go To 2


No


- The condition that caused this symptom is currently not present. 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.
- Perform POWER FOLDING SEAT SYSTEM VERIFICATION TEST - VER 1. Power Folding Seat System Verification Test


2. POWER FOLDING SEAT SWITCH SHORTED TO GROUND
With the scan tool, erase all DTC's.
Disconnect the Power Rear Folding Seat Switch harness connector.
Turn the ignition On.
With the scan tool, read DTC's.
Does the scan tool display this DTC?

Yes


- Go To 3


No


- Replace the Power Rear Folding Seat Select Switch.
- Perform POWER FOLDING SEAT SYSTEM VERIFICATION TEST - VER 1. Power Folding Seat System Verification Test


3. (P277) NORMAL/STOW SWITCH MUX CIRCUIT SHORT TO (P279) FOLDING SEAT SWITCH RETURN




Turn the ignition Off.
Disconnect the C392 seat in-line harness 12-way connector.
Measure the resistance between the (P277) Normal/Stow Switch MUX and the (P279) Folding Seat Switch Return circuit at the switch connector.
Is the resistance above 10k ohms?

Yes


- Go To 4


No


- Repair the (P277) Normal/Stow Switch MUX circuit for a short to the (P279) Folding Seat Switch Return circuit.
- Perform POWER FOLDING SEAT SYSTEM VERIFICATION TEST - VER 1. Power Folding Seat System Verification Test


4. (P277) NORMAL/STOW SWITCH MUX CIRCUIT SHORT TO GROUND




The ignition is Off.
Measure the resistance between ground and the (P277) Normal/Stow Switch MUX circuit at the switch connector.
Is the resistance above 10k ohms?

Yes


- Gain access to and check the (P277) Normal/Stow Switch MUX wire in the seat harness to the Power Rear Folding Seat Module for a short to ground condition or to another circuit. If OK, replace the Power Rear Folding Seat Module.
- Perform POWER FOLDING SEAT SYSTEM VERIFICATION TEST - VER 1. Power Folding Seat System Verification Test


No


- Repair the (P277) Normal/Stow Switch MUX circuit for a short to ground.
- Perform POWER FOLDING SEAT SYSTEM VERIFICATION TEST - VER 1. Power Folding Seat System Verification Test
