REPAIR PROCEDURE:
NOTE: Both jumper harnesses should be replaced, even if only one of the DTCs listed above
were found.
CAUTION! Disconnect and isolate the battery negative (ground) cable, then wait two minutes
for the system capacitor to discharge before performing further diagnosis or
service. This is the only sure way to disable the SRS. Failure to follow these
instructions may result in accidental airbag deployment.
1. Remove both front seats from the vehicle. Refer to the detailed service procedures available in
DealerCONNECT> Service Library under: 23 - Body/Seats, Front/Seat/Removal.
NOTE: Remove and discard seat back bolts, new bolts will be needed when putting the
seats back together.
2. Remove the seat back from the seat cushion. Refer to the detailed service procedures available
in DealerCONNECT> Service Library under: 23 - Body/Seats, Front/Seat Back, Front/Removal.
NOTE: The headrest does not have to be removed. The seat back cover does not have to be
completely removed, just opened, to gain access to the main seat harness.
3. Open the seat back cover. Refer to the detailed service procedures available in
DealerCONNECT> Service Library under: 23 - Body/Seats, Front/Seat Back, Front/
Disassembly.
4. Disconnect the seat wire harness connector from the top of the Seat Air Bag (SAB) inflator. Pull
the Connector Position Assurance (CPA) lock straight out from the connector, then pull the
connector straight out from the connector receptacle to disengage and disconnect it.
5. Cut off the SAB connector and apply tape over the wires to secure them into the harness
bundle.

(Fig. 1) for connector end view on KL vehicles. See (Fig. 2) for connector end view on
UF vehicles.
6. Remove the squib circuits from the seat to body in-line connector (left I401, right I400). The
circuit numbers for the left seat is R5 and R7 and the right seat is R6 and R8.

NOTE: The KL jumper harness may be longer than the existing seat harness, this is normal.
The jumper harness fits many KL seat configurations that need a longer harness. The
extra wire harness should be attached to the seat back harness. Take care to
attached it tight to the main seat harness, to avoid the jumper rubbing on the seat
back cover.
NOTE: Nylon tie straps are to be used at all existing main harness attachment points.
