| P16E3 PGM-FI-Battery Sensor LIN Communication Error |
DTC (PGM-FI)
- Problem verification
-1. Turn the vehicle to the ON mode.
- 2. Clear the DTC with the HDS, and wait for 60 seconds.
- 3. 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 12 volt battery sensor and the gauge control module. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot - Refer to: How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016), or How to Troubleshoot the A/T System (2014 2015), or How to Troubleshoot the Fuel and Emissions Systems .
- 12 volt battery sensor power supply check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connector.
12 volt battery sensor 2P connector - 3. 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 No. 1 (female terminals) No. 1: Test point 2 Body ground Is there battery voltage?
YES
Go to step 3.
NO
Go to step 7.
- 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 2P connector: disconnected Test point 1 12 volt battery sensor 2P connector (female terminals) No. 2: Test point 2 Body ground Is there 0 V?
YES
Go to step 4.
NO
Replace the 12 volt battery sensor - Refer to: 12 Volt Battery Sensor Removal and Installation (2014 2015), or 12 Volt Battery Sensor Removal and Installation (2016) .
- Shorted part check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check for continuity between the 12 volt battery sensor 2P connector (female terminals) terminal No. 2: and body ground, while disconnecting these connectors, one at a time:
- Gauge control module connector A (32P)
- Audio remote/HFL-navigation voice control switch 16P conenctor (with navigation)
- Audio remote-HFL/switch 16P conenctor (without navigation)
- 12 volt battery fan motor 3P connector ('17-20)
Does continuity go away when one of the above connectors is disconnected?
YES
The LIN(METER) line is OK. Replace the part that caused an open when it was disconnected.
NO
Go to step 5.
- Shorted wire check (LIN(METER) line)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connector.
Gauge control module connector A (32P) Audio remote/HFL-navigation voice control switch 16P conenctor (with navigation) Audio remote-HFL/switch 16P conenctor (without navigation) 12 volt battery fan motor 3P connector ('17-20) - 3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode 12 volt battery sensor 2P connector: disconnected Gauge control module connector A (32P): disconnected Audio remote/HFL-navigation voice control switch 16P conenctor (with navigation): disconnected Audio remote-HFL/switch 16P conenctor (without navigation): disconnected 12 volt battery fan motor 3P connector ('17-20): disconnected Test point 1 12 volt battery sensor 2P connector (female terminals) No. 2: Test point 2 Body ground Is there continuity?
YES
Repair a short in the LIN(METER) wire between the 12 volt battery sensor, the audio remote/HFL-navigation voice control switch (with navigation), the audio remote-HFL/switch (without navigation), the 12 volt battery fan motor ('17-20), and the gauge control module.
NO
The LIN(METER) wire is not shorted. Go to step 6.
- Open wire check (LIN(METER) 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 Gauge control module connector A (32P): disconnected Gauge control module connector A (32P): jumped to body ground 12 volt battery sensor 2P connector: disconnected Test point 1 12 volt battery sensor 2P connector (female terminals) No. 2: Test point 2 Body ground Is there continuity?
YES
The LIN(METER) wire is OK. Replace the gauge control module .
NO
Repair an open in the LIN(METER) wire between the 12 volt battery sensor and the gauge control module.
- Fuse check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check the following fuse.
Fuse No. B10 (7.5 A) Location Main under-hood fuse box Is the fuse OK?
YES
Repair an open in the +B BMS wire between the 12 volt battery sensor and the No. B10 (7.5 A) fuse in the main under-hood fuse box.
NO
Repair a short in the +B BMS wire between the 12 volt battery sensor and the No. B10 (7.5 A) fuse in the main under-hood fuse box. Also replace the No. B10 (7.5 A) fuse.
