Diagnosis Description

AUTO ACTIVE TEST

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

  • 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, place ignition switch OFF.

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

  2. Ignition switch OFF.

  3. Ignition switch ON, and within 20 seconds, press the front door switch LH 10 times. Then place the ignition switch OFF.

  4. Ignition switch ON within 10 seconds. After 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.

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 Headlamps LO ⇔ HI 5 times
4 A/C compressor ON ⇔ OFF 5 times
5 Cooling fans LO for 5 seconds → MID for 3 seconds → HI for 2 seconds

Concept of 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.

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

  • 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

  • Cooling fan relay

  • Harness or connectors between IPDM E/R and cooling fan relay

  • IPDM E/R

CONSULT Function (IPDM E/R)

CAUTION:

After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go to "sleep mode", potentially causing a discharged battery and a no-start condition.
