2006 INFINITI QX56 sensor

RSU-46
HEIGHT SENSOR
Revision: November 20092006 QX56
INSTALLATION
Installation is in the reverse order of removal.
1. Start the engine.
2. Use CONSULT-II to perform "STANDARD HEIGHT LEVEL" work support function.
3. Using data monitor of CONSULT-II, verify "HEIGT CALC" is at 0 mm.
4. Check the vehicle height. Refer to RSU-49, "
Wheelarch Height (Unladen*1 )" . If vehicle height is not
within ± 10 mm (0 ± 0.39 in) of the specification, perform the initialization procedure. Refer to RSU-47,
"Initialization Procedure" .

Removal
CAUTION:

Before servicing SRS, turn the ignition switch off, disconnect both battery cables and wait at least
3 minutes.
1. Remove the center pillar upper/lower finishers. Refer to EI-35, "
BODY SIDE TRIM" .
2. Remove the seat belt retractor anchor bolts and seat belt retractor and belt assembly.

On RH side, disconnect the seat belt tension sensor.
3. Disconnect the seat belt pre-tensioner electrical connector. CAUTION:

For removing pre-tensioner connector, insert a thin
screwdriver (1) wrapped in tape (3) into the notch. Lift the
locking tab to unlock (2), then remove the connector.

Install the pre-tensioner connector with the locking tab
raised, then push the locking tab into the connector to
lock (4).
Installation
Installation is in the reverse order of removal.

Install the seat belt retractor and belt assembly upper bolt first.

Ensure that seat belt height adjuster is locked in the lowest position during installation.
