^ If the SRS unit part number is NOT 77960-SHJ- A02, or it is NOT 77960-SHJ-A01 with a blue dot on the unit, go to REPAIR PROCEDURE to install a new SRS unit.
^ If the SRS unit part number is 77960-SHJ-A02, or 77960-SHJ-A01 with a blue dot on the unit, go to REPAIR PROCEDURE to reinstall the SRS unit, then do the service manual troubleshooting for the DTC found.
REPAIR PROCEDURE
1. Install the SRS unit with the TORX bolts, and torque the bolts to 9.8 Nm (7.2 lb-ft). Connect the three connectors to the SRS unit, and push them into position until they click.
NOTE:
Make sure the SRS unit is sitting squarely against its mounting bracket before torquing the TORX bolts.
2. Reconnect both seat belt tensioner connectors.
3. Reinstall all removed parts, and note the following:
^ Make sure that each connector is plugged in properly.
^ Replace any damaged clips.
^ Torque the lower anchor bolt to 32 Nm (24 lb-ft).
4. Reconnect the negative cable to the battery.
5. Confirm proper SRS operation: Turn the ignition switch to the ON (II) position; the SRS indicator should come on for about 6 seconds and then go off.
6. Enter the audio and navigation security codes, then enter the customer's audio presets. Set the clock.

^ Turn off the main power sliding door switch, and make sure the ignition switch is in LOCK (0).
^ Fully close the power sliding door manually (the control unit must see the full latch switch and the ratchet switch closed at the same time).
^ Turn the ignition switch to ON (II), and turn on the main power sliding door switch.
^ Test the door operation with the power sliding door switch, the remote transmitter, and the inside and outside door handles.
