HOOD
3. Remove the hood lock assembly.
4. Disconnect the hood lock cable from the hood lock, and clip it from the radiator core support upper and
hood ledge.
5. Remove the hood lock opener mounting bolts, and remove the
hood lock opener.
6. Separate the grommet from the lower dash panel. Pull the hood
lock cable out through the passenger compartment.
CAUTION:
While pulling, be careful not to damage (peeling) the out-
side of the hood lock cable.
INSTALLATION
1. Pull the hood lock cable through the panel hole to the engine
room.
CAUTION:
Be careful not to bend the cable too much, keeping the
radius 100 mm (3.94 in) or more.
2. Make sure the cable is not offset from the positioning grommet,
and push the grommet into the panel hole securely.
3. Apply the sealant to the grommet (at * mark) properly.
4. Install the cable securely to the lock in order of (1) and (2).
5. After installing, check the hood lock adjustment and hood
opener operation.
6. After installing, perform hood fitting adjustment. Refer toBL-12,
"Fitting Adjustment". : 23.0 N·m (2.3 kg-m, 17.0 ft-lb)

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)”.

BCM diagnosis
partDiagnostic mode Description
THEFT ALMWORK SUPPORTSupports inspections and adjustments. Commands are transmitted to the BCM
for setting the status suitable for required operation, input/output signals are
received from the BCM and received data is displayed.
DATA MONITOR Displays BCM input/output data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
