Diagnostic Test

WARNING: This page is about a different car, the 2015 Fiat 500. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK THE SERVICE DISCONNECT INTERNAL FUSE FOR AN OPEN CIRCUIT 
    NOTE:

    If the high voltage Service Disconnect is removed from the vehicle while the ignition is on, this DTC will set. Make sure if any work was performed on the vehicle to reinstall the Service Disconnect and clear this DTC.

    1. Turn the ignition off.
    2. Remove the high voltage Service Disconnect in accordance with the Service Information. Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE .
    3. Measure the resistance between the high voltage contacts in the service disconnect.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go To  2

      No 

  2. CHECK BPCM FAIL TYPE 
    1. With the scan tool, check the environmental data.
    2. In the scan tool, go to BPCM/ Data Read/ FUSI-Current Sensor Performance Shunt vs. Hall.

      Does FUSI - Current Sensor Performance Shunt vs. Hall display FAIL under the value?

      Yes 

      • Go To  3.

      No 

      • Go T0

        Refer to  4.

  3. CHECK THE AIR ELECTRIC HEATER (AEH) OPERATION 
    NOTE:

    Before performing any test with the Fluke 1587 or equivalent multi-meter, check the internal fuse (located next to the AA batteries in the Fluke 1587). Place the multi-meter leads into the (+) and (-) Insulation Ports, make sure you are on the 500V scale, and then place the selector to "Insulation Scale". Touch the Positive and negative lead together and hold. Press and hold the Isolation button. If a value of 550 k ohms is displayed, then the internal fuse is open and must be replaced before performing the Diagnostic Procedure.

    1. Disconnect the AEH high voltage connector C2 at the HVPDC.
    2. Disconnect the ground from the vehicle at the AEH.
    3. Place the Fluke 1587 selector to "Insulation Scale". Make sure the Fluke 1587 is at the 500V scale.
    4. Connect the Fluke 1587 Insulation black probe to the AEH ground (that was disconnected).
    5. Connect the Fluke 1587 Insulation red probe to either terminal of the disconnected high voltage connector C2 at the HVPDC.
    6. Press and hold the Insulation button on the Fluke 1587.

      Does the Fluke 1587 show a value less than 550 k ohms? 

      Yes 

      No 

  4. CHECK FOR ACTIVE OR STORED DTC P1A21-00 HV BATTERY CONTACT OR CONTROL SEQUENCE INCORRECT 
    NOTE:

    If DTC P1A21-00 HV BATTERY CONTACT OR CONTROL SEQUENCE INCORRECT is set as Active/stored along with this DTC, diagnose P1A21-00 first.

    1. Reinstall the high voltage Service Disconnect in accordance with the Service Information. Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE .
    2. Turn the ignition on.
    3. With the scan tool, read DTCs.

      Is the status Active for DTC P1A21-00 HV BATTERY CONTACTOR CONTROL SEQUENCE INCORRECT and also this DTC?

      Yes 

      • Diagnose DTC P1A21-00 HV BATTERY CONTACTOR CONTROL SEQUENCE INCORRECT in accordance with the Service Information.
      • Perform the BATTERY PACK CONTROL MODULE (BPCM) VERIFICATION TEST. Refer to BPCM VERIFICATION TEST .

      No 

      • Go To  5
  5. ACTIVE DTC 
    1. Turn the ignition on.
    2. With the scan tool, record and erase BPCM DTCs.
    3. Turn the ignition off and close all doors. Wait three minutes.
    4. Turn the ignition on. Wait three minutes.
    5. With the scan tool, read DTCs.

      Is the status Active for this DTC?

      Yes 

      • Go To  7

      No 

      • Go To  6
  6. STORED DTC 
    NOTE:

    DTC P1E25-00 has set as Stored or did not reset.

    1. With the scan tool, record and erase BPCM DTCs.
    2. Cycle the ignition key from off to on twenty times. Listen for the high voltage battery contactors to open and close each time the ignition is cycled from off to on.
    3. Turn the ignition on.
    4. With the scan tool, record and erase BPCM DTCs.
    5. Turn the ignition off and close all doors. Wait three minutes.
    6. Turn the ignition on. Wait three minutes.
    7. With the scan tool, read DTCs.

      Did DTC P1E25-00 reset after performing the twenty key cycles where the contactors could be heard opening and closing or has this vehicle been previously diagnosed and returned with DTC P1E25-00 set as Active or Stored?

      Yes 

      No 

      • Monitor this vehicle to see if it returns in the future with any BPCM DTCs.
      • The condition or conditions that originally set this DTC are not present at this time. Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
  7. 12 VOLT BATTERY 
    NOTE:

    DTC P1E25-00 may set if there is an issue with the 12 Volt Battery. After resolving the 12 Volt battery issue, DTC P1E25-00 may take several attempts to clear using the scan tool. Continue clearing DTCs until this code clears.
