Yes

• Go to Test Step 4 => [ Test
Step 4 - Normal/Stow Switch MUX Circuit Short to Ground ]

No

• Repair the normal/stow switch MUX circuit for a short to the folding seat switch return circuit.

• Perform Power Folding Seat System Verification Test. Refer to => Non - DTC Based Diagnostics. Power Folding Seat System Verification Test

Test Step 4 - Normal/Stow Switch MUX Circuit Short to Ground






• The ignition is Off.

• Measure the resistance between ground and the normal/stow switch MUX circuit at the switch connector.

Is the resistance above 10k ohms?

Yes

• Gain access to and check the 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.
