Auto Active Test

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

Description

In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.

Oil pressure low warning indicator
Rear window defogger (if equipped)
Front wipers
Tail, license plate, side marker and parking lamps
Front fog lamps (if equipped)
Headlamps (Hi, Lo)
A/C compressor (magnetic clutch)
Cooling fan

Operation Procedure

Close the hood and front door RH, and lift the wiper arms from the windshield (to prevent windshield damage due to wiper operation).
NOTE: When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
Turn ignition switch OFF.
Turn the ignition switch ON and, within 20 seconds, press the front door switch LH 10 times. Then turn the ignition switch OFF.
Turn the ignition switch ON within 10 seconds. After that, the horn sounds once and the auto active test starts.
After a series of the following operations is repeated 3 times, auto active test is completed.

NOTE: When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.

CAUTION:

If auto active test mode cannot be actuated, check door switch system. Refer to DTC Diagnosis Procedure .
Do not start the engine.

Inspection in Auto Active Test Mode

When auto active test mode is actuated, the following operation sequence is repeated 3 times.

Operation sequence	Inspection Location	Operation
1	Oil pressure low warning indicator	Blinks continuously during operation of auto active test
2	Rear window defogger (if equipped)	10 seconds
3	Front wipers	LO for 5 seconds -> HI for 5 seconds
4	Tail, license plate, side marker, parking lamps and front fog lamps (if equipped)	10 seconds
5	Headlamps	LO for 10 seconds -> HI on-off for 5 seconds
6	A/C compressor	ON <=> OFF 5 times
7	Cooling fan	10 seconds

Concept of auto active test

Courtesy of NISSAN NORTH AMERICA, INC.

IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communication. 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.

Diagnosis chart in auto active test mode

Symptom	Inspection contents		Possible cause
Oil pressure low warning indicator does not operate	Perform auto active test. Does the oil pressure low warning indicator blink?	YES	IPDM E/R signal input circuit CAN communication signal between ECM and combination meter Oil pressure switch wiring Oil pressure switch
		NO	CAN communication signal between IPDM E/R, BCM and combination meter
Rear window defogger (if equipped) does not operate	Perform auto active test. Does the rear window defogger operate?	YES	BCM signal input circuit
		NO	Harness or connector between front air control CAN communication signal between BCM and IPDM E/R Rear window defogger Rear window defogger ground IPDM E/R
Any of the following components do not operate Front wipers Tail lamps License plate lamps Parking lamps Front fog lamps (if equipped) Headlamps (Hi, Lo) Side marker lamps	Perform auto active test. Does the applicable system operate?	YES	BCM signal input system
		NO	Lamp or front wiper motor malfunction Lamp or front wiper motor ground circuit Harness or connector between IPDM E/R and applicable system IPDM E/R
A/C compressor does not operate	Perform auto active test. Does the A/C compressor operate?	YES	BCM signal input circuit CAN communication signal between BCM and ECM CAN communication signal between ECM and IPDM E/R
		NO	Magnetic clutch malfunction Harness or connector between IPDM E/R and magnetic clutch IPDM E/R (integrated relay malfunction)
Cooling fan does not operate	Perform auto active test. Does the cooling fan operate?	YES	ECM signal input circuit CAN communication signal between ECM and IPDM E/R
		NO	Cooling fan motor malfunction Harness or connector between IPDM E/R and cooling fan IPDM E/R (integrated relay malfunction)
