NOTE:
DTC Description Confirmed DTC Pending DTC
P16E3 PGM-FI-Battery Sensor LIN Communication Error    

DTC (PGM-FI)

  1. Problem verification

    -1. Turn the vehicle to the ON mode.

    -2. Clear the DTC with the HDS.

    -3. Turn the vehicle to the OFF (LOCK) mode.

    -4. Turn the vehicle to the ON mode, and wait for 60 seconds.

    -5. Check for Pending or Confirmed DTCs with the HDS.

    P16E3 PGM-FI-Battery Sensor LIN Communication Error    

    DTC (PGM-FI)

    Is DTC P16E3 indicated?

    YES 

    Go to step 2.

    NO 

    Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the 12 volt battery sensor and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

  2. Open wire check (BATT SNSR line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Disconnect the following connector.

    12 volt battery sensor 3P connector

    -3. Measure the voltage between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
      12 volt battery sensor 3P connector: disconnected
    Test point 1 12 volt battery sensor 3P connector (female terminals) No. 2:
    Test point 2 Body ground

    Is there battery voltage?

    YES 

    The BATT SNSR wire is OK. Go to step 4.

    NO 

    Go to step 3.

  3. Fuse check

    -1. Check the No. D2 fuse .

    Is the fuse OK?

    YES 

    Repair an open in the BATT SNSR wire between the No. D2 fuse and the 12 volt battery sensor.

    NO 

    Repair a short in the BATT SNSR wire between the No. D2 fuse and the 12 volt battery sensor. Also replace the No. D2 fuse.

  4. Determine possible failure area (12 volt battery sensor, others)

    -1. Turn the vehicle to the ON mode.

    -2. Measure the voltage between test points 1 and 2.

    Test condition Vehicle ON mode
      12 volt battery sensor 3P connector: disconnected
    Test point 1 12 volt battery sensor 3P connector (female terminals) No. 3:
    Test point 2 Body ground

    Is there about 0 V?

    YES 

    Go to step 5.

    NO 

    Replace the 12 volt battery sensor .

  5. Shorted wire check (LIN(BATT SENSOR) line)

    -1. Turn the vehicle to the OFF (LOCK) mode.

    -2. Jump the SCS line with the HDS, and wait more than 1 minute.

    -3. Disconnect the following connector.

    PCM connector A (50P)

    -4. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    12 volt battery sensor 3P connector: disconnected
    PCM connector A (50P): disconnected
    Test point 1 12 volt battery sensor 3P connector (female terminals) No. 3:
    Test point 2 Body ground

    Is there continuity?

    YES 

    Repair a short in the LIN(BATT SENSOR) wire between the PCM (A10) and the 12 volt battery sensor.

    NO 

    The LIN(BATT SENSOR) wire is not shorted. Go to step 6.

  6. Open wire check (LIN(BATT SENSOR) line)

    -1. Check for continuity between test points 1 and 2.

    Test condition Vehicle OFF (LOCK) mode
    12 volt battery sensor 3P connector: disconnected
    PCM connector A (50P): disconnected
    Test point 1 12 volt battery sensor 3P connector (female terminals) No. 3:
    Test point 2 PCM connector A (50P) No. 10
    GHH385347Courtesy of HONDA, U.S.A., INC.

    Is there continuity?

    YES 

    The LIN(BATT SENSOR) wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM , then recheck. If DTC P16E3 goes away and the PCM was substituted, replace the original PCM .

    NO 

    Repair an open in the LIN(BATT SENSOR) wire between the PCM (A10) and the 12 volt battery sensor.
