AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation:
• Front wiper (LO, HI)
• Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan
Operation Procedure
NOTE:
Never perform auto active test in the following conditions:
• Passenger door is open
• CONSULT is connected
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
• When auto active test has to be cancelled halfw ay through test, turn the ignition switch OFF.
• When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-98,
"ComponentFunctionCheck" (with Intelligent Key system) or DLK-232, "ComponentFunctionCheck"
(without Intelligent Key system).
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation se-
quence Inspection location
Operation
1 Front wiper LO for 5 seconds → HI for 5 seconds
2 •Parking lamp
• Side marker lamp
• License plate lamp
• Tail lamp
• Front fog lamp (if equipped) 10 seconds
3 Headlamp LO for 10 seconds →HI ON ⇔ OFF 5 times
4 A/C compressor (magnet clutch) ON ⇔ OFF 5 times

Concept of Auto Active Test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

CAUTION:
• Never tow a CVT model with the rear wheels raised and the front wheels on the ground. This may
cause serious and expensive damage to the transaxle. If it is necessary to tow the vehicle with the
rear wheels raised, always use towin g dollies under the front wheels.
• Never tow a CVT model from the rear (that is b ackward) with four wheels on the ground. This may
cause serious and expensive damage to the transaxle.
NISSAN recommends that the vehicle be towed with the driving
(front) wheels off the ground.
CAUTION:
• Always release the parking br ake when towing the vehicle
with the front wheels raised with the rear wheels on the
ground.
• When towing manual transaxle models with the front wheels on the ground (if a towing dolly is not used), turn the ignition
key to the OFF position, and secu re the steering wheel in the
straight-ahead position with a rope or similar device.
Move the shift lever to th e N (Neutral) position.
Vehicle Recovery (Freeing a Stuck Vehicle)INFOID:0000000012433174
FRONT
WARNING:
• Stand clear of a stuck vehicle.
• Do not spin your tires at high speed. This could cause them to explode and result in serious injury.
Parts of your vehicle could also overheat and be damaged.
CAUTION:
• Tow chains or cables must be attached only to the vehicle recovery hooks or main structural mem-
bers of the vehicle. Otherwise, the vehicle body will be damaged.
• Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow the vehi-
cle using the vehicle tie downs or recovery hooks.
• Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or
cooling systems.
• Pulling devices such as ropes or canvas straps ar e not recommended for use in vehicle towing or
recovery.
CVT
To tow a vehicle equipped with a CVT, an appropriate vehicle dolly MUST be placed under the towed vehicle's
drive wheels. Always follow the dolly manufacture's re commendations when using their product.
If the vehicle is stuck in sand, snow , mud, etc., use the following procedure:
1. Make sure the area in front and behind the vehicle is clear of obstructions.
2. Turn the steering wheel right and left to clear an area around the front tires.

YES >> GO TO 3.
NO >> Adjust or replace drive belt depending on the inspection results.
3.CHECK REFRIGERANT CYCLE PRESSURE
Connect the recovery/recycling recharging equipment to the vehicle and perform the pressure inspection
using gauge. Refer to HA-15, "
Symptom Table".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace parts depending on the inspection results.
4.CHECK AIR LEAKAGE FROM EACH DUCT
Check duct and nozzle, etc. of t he air conditioner system for leakage.
Is the inspection result normal?
