DTC P16E3

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

NOTE: 

• Before you troubleshoot, review the general troubleshooting information .
• Check for loose terminals on the 12 volt battery sensor (12 volt battery negative (-) terminal).

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 10 seconds.

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

   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 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. DTC check

   -1. Check for Pending or Confirmed DTCs with the HDS.

   P16E8 PGM-FI-Shutter Grille LIN Communication Error

   Is DTC P16E8 indicated?

   YES 

   Go to step 3.

   NO 

   Go to step 7.

3. Determine possible failure area (short in LIN(BATT_SENSOR) line, others)

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

   -2. Disconnect the following connector.

   12 volt battery sensor 2P connector

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

   Test condition	Vehicle OFF (LOCK) mode

   Is there 1 MΩ or more?

   YES 

   Go to step 5.

   NO 

   Go to step 4.

4. Shorted wire check (LIN(BATT_SENSOR) line)

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

   Continue to check for continuity between 12 volt battery sensor 2P connector (female terminals) terminal No. 2 and body ground, while disconnecting these connectors, one at a time:

   • PCM connector A (50P)
   • Shutter grille 4P connector

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

   YES 

   The LIN(BATT_SENSOR) wire is OK. Replace the part that caused an open when it was disconnected.

   NO 

   Repair a short in the LIN(BATT_SENSOR) wire between the PCM (A10), the 12 volt battery sensor, and the shutter grille.

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

   -1. Reconnect the 12 volt battery sensor 2P connector.

   -2. Disconnect the following connector.

   Shutter grille 4P connector

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

   Test condition	Vehicle OFF (LOCK) mode
   	Shutter grille 4P connector: disconnected
   Test point 1	Shutter grille 4P connector (female terminals) No. 3:
   Test point 2	Body ground

   Is there 1 MΩ or more?

   YES 

   Go to step 6.

   NO 

   Replace the 12 volt battery sensor .

6. Open wire check (LIN(BATT_SENSOR) line)

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

   -2. Disconnect the following connectors.

   PCM connector A (50P)

   12 volt battery sensor 2P connector

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

   Test condition	Vehicle OFF (LOCK) mode
   	Shutter grille 4P connector: disconnected
   	PCM connector A (50P): disconnected
   	12 volt battery sensor 2P connector: disconnected
   Test point 1	12 volt battery sensor 2P connector (female terminals) No. 2:
   Test point 2	PCM connector A (50P) No. 10

   Is there 1.0 Ω or less?

   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 .

   NO 

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

7. Fuse check

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

   -2. Check the following fuse.

   Fuse

   No. A24

   Is the fuse OK?

   YES 

   Go to step 8.

   NO 

   Repair a short in the +B_HORN wire between the No. A24 fuse and the 12 volt battery sensor. Also replace the No. A24 fuse.

8. Open wire check (+B_HORN line)

   -1. Disconnect the following connector.

   12 volt battery sensor 2P connector

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

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

   Courtesy of HONDA, U.S.A., INC.

   Is there battery voltage?

   YES 

   Go to step 9.

   NO 

   Repair an open in the +B_HORN wire between the No. A24 fuse and the 12 volt battery sensor.

9. Open wire check (LIN(BATT_SENSOR) line)

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

   -2. Disconnect the following connector.

   PCM connector A (50P)

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

   Test condition	Vehicle OFF (LOCK) mode
   	12 volt battery sensor 2P connector: disconnected
   	PCM connector A (50P): disconnected
   Test point 1	12 volt battery sensor 2P connector (female terminals) No. 2:
   Test point 2	PCM connector A (50P) No. 10

   Is there 1.0 Ω or less?

   YES 

   The LIN(BATT_SENSOR) wire is OK. Replace the 12 volt battery sensor .

   NO 

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