 Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF is not to be fluctuated by being overloaded.
 Turn wiper intermittent dial position to 4 except when checking waveform or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT -III. Refer to
BCS-24, "
COMB SW : CONSULT-III Function (BCM - COMB SW)".
 BCM reads the status of the combination switch at 10 ms internal normally. Refer to BCS-7, "

1. Remove headlining. Refer to INT-29, "Component".
2. Visually check drain hoses for:
 Proper connection at sunroof unit assembly.
 Damage, pinch, cracks, deterioration.
 Proper fastening and routing on body panels.
3. Pour water through drain hoses to determine watertight performance.
If a damaged or leaking portion in any drain hose is found, replace entire drain hose as an assembly.
Fitting AdjustmentINFOID:0000000001724430
GAP ADJUSTMENT
1. Tilt up glass lid.
2. Loosen glass lid bolts, then tilt down glass lid.
3. Adjust glass lid from outside of vehicle so it resembles “A–A” “B–
B” “C–C” as shown in the figure.
 For gap adjustment "A-A" "C-C", carefully slide glass lid for-
ward and rearward in vehicle.
 For gap adjustment "B-B", loosen sunroof unit assembly and
shift side to side.
NOTE:
To prevent glass lid from moving after adjustment, lightly tighten
the bolts.
4. Tighten left front bolt, then right rear bolt to prevent uneven
torque. Tighten remaining bolts, being careful to prevent glass
lid from moving.
5. Tilt glass lid up and down several times to check that it moves smoothly, and retains the adjustment.
HEIGHT ADJUSTMENT
1. Tilt up glass lid.
2. Loosen glass lid bolts, then tilt down glass lid.
3. Adjust glass lid from outside of vehicle so it resembles "A-A" "B-B" "C-C" as shown in the figure.
 For height adjustment, manually raise/lower glass lid assembly until height difference is within specifica-
tions.

VEHICLE SECURITY INDICATOR
DescriptionINFOID:0000000001404115
 Vehicle security indicator is located on top left side of the instrument panel near the autolight sensor.
 NATS (Nissan Anti-Theft System) and vehicle security system conditions are indicated by blink or illumina-
tion of vehicle security indicator.
Component Function CheckINFOID:0000000001404116
1.CHECK FUNCTION
1. Perform “THEFT IND” in the “Active Test” mode with CONSULT-III.
2. Check vehicle security indicator operation.
Is the inspection result normal?
YES >> INSPECTION END.
NO >> Refer to SEC-49, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001404117
1.CHECK SECURITY INDICATOR LAMP POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect security indicator lamp connector.
3. Check voltage between security indicator lamp harness connec-
tor and ground.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace harness.
2.CHECK SECURITY INDICATOR LAMP SIGNAL CIRCUIT
1. Disconnect Intelligent Key unit connector.

REAR WIPER CONTROL
BCM detects a rear wiper stopping position according to a rear wiper auto stop signal.
When a rear wiper auto stop signal is in the condition listed below, BCM stops power supply to rear wiper after
rear wiper is activated for five seconds.
NOTE:
The above operation is repeated when operating the rear wiper switch one minute after the stop of the rear
wiper caused by Fail-safe.
TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
Headlamp is turned ON.
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.

 Possible symptom of NATS malfunction is “Engine cannot start” In J10, the engine can be started with the
NATS. Identify the possible causes according to “Work Flow”. Refer to SEC-80, "
Work Flow".
 If ECM other than Genuine NISSAN is installed, the engine cannot be started. For ECM replacement proce-
dure, refer to SEC-83, "
ECM RE-COMMUNICATING FUNCTION : Description".
PRECAUTIONS FOR KEY REGISTRATION
 The key registration is a procedure that erases the current NATS ID once, and then re-registers a new ID.
Therefore the registered ignition key is necessary for this procedure. Before starting the registration opera-
tion collect all registered ignition keys from the customer
 The NATS ID registration is the procedure that registers the ID stored into the transponder (integrated in
ignition key) to BCM.
SECURITY INDICATOR
 Security indicator blinks when the ignition switch is in “OFF” or “ACC” position.
 When NATS detects trouble, the security indicator lamp lights up while ignition key is in the “ON” position.
MAINTENANCE INFORMATION
CAUTION:
If necessary to perform NATS ID registration when replacing any of the following part.
If it's not (or fail to do so), the electrical system may not operate properly.
