Nissan Sentra Service Manual: Diagnosis system (ipdm e/r) (without intelligent key system)
Diagnosis Description
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
- License plate lamp
- Tail lamp
- Front fog lamp (if equipped)
- Headlamp (LO, HI)
- A/C compressor (magnet clutch) (if equipped)
- Cooling fan
Operation Procedure
NOTE:
Never perform auto active test in the following conditions.
- Passenger door is open
- CONSULT is connected
- 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.
- Turn the ignition switch OFF.
- Turn the ignition switch ON, and within 20 seconds, press the driver door switch 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 has to be cancelled halfway through test, turn the ignition switch OFF.
- When auto active test is not activated, door switch may be the cause. Check door switch. Refer to DLK-255, "Component Inspection".
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Diagnosis Chart in Auto Active Test
- 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.
