B1E96 - Left Folding Seat Not Latched






For a complete wiring diagram, refer to.

• When Monitored: During normal or fold activation.

• Set Condition: If the folding seat module does not detect after one second that the latch switches are closed after the seat reaches it's Normal position.






Test Step 1 - Inspect Seat Mechanical Operation


To avoid bodily injury while the folding seat is in operation, keep clear of the seat leg latch striker pocket as the seat leg reaches it's fully latched position.

• Gain access to and inspect the following components:

• Object or obstruction in seat latch striker pocket or seat leg for a binding condition.

• Check seat leg latch mechanical operation by manually closing and releasing each latch and note any sticking, wear or damage.

• Inspect each seat leg latch micro switch for proper mechanical operation.

• Broken seat welds or frame.

• Manually operate the latch release actuator and check for any binding in the latch release cable system.

Were any problems found?

No

• Go to Test Step 2 => [ Test Step 2 - Check for DTCs ]

Yes

• Repair or replace components as necessary.

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

Test Step 2 - Check for DTCs

• Turn the ignition ON.

• With the scan tool, record and erase all DTCs.

• Operate the folding seat switch several times.

• With the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

• Go to Test Step 4 => [ Test Step 4 - Check Each Latch Switch ]

No

• Using the wiring diagrams as a guide, inspect the wiring and connectors for an intermittent condition.

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

Test Step 3 - Check the Latch Switch Function

• Disconnect both left power rear folding seat latch switch connectors.

• Measure the resistance of each switch. With the latch in the unlatched position the switch should measure open and in the latched position the switch should measure closed.

Do the latch switches operate correctly?

Yes

• Go to Test Step 4 => [ Test Step 4 - Check the Left Seat Latch Switch Sense Circuit for
an Open ]

No

• Replace the seat latch switch as necessary.

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

Test Step 4 - Check the Left Seat Latch Switch Sense Circuit for an Open






• Disconnect the folding seat module C1 harness connector.

• Measure the resistance of the left seat latch switch sense circuit between the folding seat module C1 connector and the left power rear folding seat latch 1 switch connector.

Is the resistance below 3.0 ohms?

Yes

• Go to Test Step 5 => [ Test Step 5 - Check the Seat Latch Switch Return Circuit An Open ]

No

• Repair the left seat latch switch sense circuit for an open.

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

Test Step 5 - Check the Seat Latch Switch Return Circuit An Open






• Connect a jumper wire across the disconnected left power rear folding seat latch 2 switch connector.

• Measure the resistance of the seat latch switch return circuit at the folding seat module C1 connector to the left power rear folding seat latch 1 switch connector.

Is the resistance below 3.0 ohms?

Yes

• Replace the folding seat module.

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

No

• Repair the seat latch switch return circuit for an open.
