Auto Active Test

WARNING: This page is about a different car, the 2019 Infiniti QX60. 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.

Front wiper (LO, HI)
Front fog lamps
Parking lamps
Side marker lamps
Tail lamps
License plate lamps
Daytime running lamps
Headlamps (LO, HI)
A/C compressor
Cooling fans (LO, HI)

Operation Procedure

CAUTION: Do not start the engine.

NOTE: When auto active test is performed with hood opened, sprinkle water on windshield before hand.

NOTE:

If auto active test mode cannot be actuated, check door switch system. Refer to Component Function Check .
When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.

Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper operation)
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.

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	Front wiper	LO for 3 seconds -> HI for 3 seconds
2	Front fog lamps Parking lamps Side marker lamps Tail lamps License plate lamps	10 seconds
3	Daytime running lamps	10 seconds
4	Headlamps	LO <=> HI 5 times
5	A/C compressor	ON <=> OFF 5 times
6^*	Cooling fans	LO for 5 seconds -> HI for 5 seconds

*: Outputs duty ratio of 50% for 5 seconds -> duty ratio of 100% for 5 seconds on the cooling fan control module.

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
Any of the following components do not operate Front fog lamps Parking lamps Side marker lamps License plate lamps Tail lamps Daytime running lamps Headlamp (HI, LO) Front wiper	Perform AUTO ACTIVE TEST . Does the applicable system operate?	YES	BCM signal input circuit
		NO	Lamp or motor Lamp or motor ground circuit Harness or connector between IPDM E/R and applicable system IPDM E/R
Cooling fans do not operate	Perform AUTO ACTIVE TEST . Do the cooling fans operate?	YES	ECM signal input circuit CAN communication signal between ECM and IPDM E/R
		NO	Cooling fans Harness or connectors between cooling fans and cooling fan control module Cooling fan control module Harness or connectors between cooling fan relay and cooling fan control module Cooling fan relay Harness or connectors between IPDM E/R and cooling fan relay IPDM E/R
