DTC P16E3  : PGM-FI-Battery Sensor LIN Communication Error

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.

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

    Is DTC P16E3 indicated?

    YES 

    The failure is duplicated. Go to step 2.

    NO 

    Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the battery sensor, the gauge control module, and the steering commander switch assembly. 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. Battery sensor power supply check

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

    -2. Disconnect the following connector.

    Battery sensor 3P connector

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

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

    Is there battery voltage?

    YES 

    Go to step 3.

    NO 

    Go to step 7.

  3. Determine possible failure area (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
      Battery sensor 3P connector: disconnected
    Test point 1 Battery sensor 3P connector (female terminals) No. 3:
    Test point 2 Body ground

    Is there 0 V?

    YES 

    Go to step 4.

    NO 

    Replace the battery sensor .

  4. Shorted part check

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

    -2. Check for continuity between battery sensor 3P connector (female terminals) terminal No. 3: and body ground, while disconnecting these connectors, one at a time:

    • Gauge control module connector A (32P)
    • Steering commander switch assembly connector B (16P)

    Does continuity go away when one of the above connectors is disconnected?

    YES 

    Replace the part that caused an open when it was disconnected.

    NO 

    Go to step 5.

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

    -1. Disconnect the following connectors.

    Gauge control module connector A (32P)
    Steering commander switch assembly connector B (16P)

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

    Test condition Vehicle OFF (LOCK) mode
      Battery sensor 3P connector: disconnected
      Gauge control module connector A (32P): disconnected
      Steering commander switch assembly connector B (16P): disconnected
    Test point 1 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)/LIN wire between the battery sensor, the gauge control module, and the steering commander switch assembly.

    NO 

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

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

    -1. Connect terminals A and B with a jumper wire.

    Terminal A Gauge control module connector A (32P) (female terminals) No. 24:
    Terminal B Body ground

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

    Test condition Vehicle OFF (LOCK) mode
      Battery sensor 3P connector: disconnected
      Gauge control module connector A (32P): disconnected
      Steering commander switch assembly connector B (16P): disconnected
      Gauge control module connector A (32P) No. 24: jumped to body ground
    Test point 1 Battery sensor 3P connector (female terminals) No. 3:
    Test point 2 Body ground
    GHH345163Courtesy of HONDA, U.S.A., INC.

    Is there continuity?

    YES 

    The LIN(BATT SENSOR) wire is OK. Replace the gauge control module .

    NO 

    Repair an open in the LIN(BATT SENSOR) wire between the battery sensor and the gauge control module.

  7. Fuse check

    -1. Check the following fuse.

    Fuse No. B11

    Is the fuse OK?

    YES 

    Repair an open in the +B HORN wire between the battery sensor and the No. B11 fuse.

    NO 

    Repair a short in the +B HORN wire between the battery sensor and the No. B11 fuse. Also replace the No. B11 fuse.
