| P16E7 PGM-FI-Battery Fan LIN Communication Error |
DTC (PGM-FI)
- Problem verification
-1. Turn the vehicle to the ON mode.
- 2. Clear the DTC with the HDS.
- 3. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC P16E7 PGM-FI-Battery Fan LIN Communication Error Is DTC P16E7 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 fan motor 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 - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or 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) .
- Determine possible failure area (IG1 OPTION line, BATT FAN GND line, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connector.
12 volt battery fan motor 3P connector - 3. Turn the vehicle to the ON mode.
- 4. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode 12 volt battery fan motor 3P connector: disconnected Test point 1 12 volt battery fan motor 3P connector (male terminals) No. 1: Test point 2 12 volt battery fan motor 3P connector (male terminals) No. 3: Is there battery voltage?
YES
Go to step 3.
NO
Go to step 7.
- Determine possible failure area (LIN(METER) line shorted, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode 12 volt battery fan motor 3P connector: disconnected Test point 1 12 volt battery fan motor 3P connector (male terminals) No. 2: Test point 2 Body ground Is there continuity?
YES
Go to step 4.
NO
The LIN(METER) wire is not shorted. Go to step 5.
- Shorted wire check (LIN(METER) line)
-1. Jump the SCS line with the HDS, and wait more than 1 minute.
- 2. Continue to check for continuity between 12 volt battery fan motor 3P connector terminal No. 2 and body ground, while disconnecting these connectors, one at a time:
- Gauge control module connector A (32P)
- Cable reel connector A (20P)
Does continuity go away when one of the above connectors is disconnected?
YES
The LIN(METER) wire is OK. Replace the part that caused an open when it was disconnected. If these parts are OK, replace the 12 volt battery fan motor .
NO
Repair a short in the LIN(METER) wire between the gauge control module, the cable reel, and the 12 volt battery fan motor.
- Open wire check (LIN(METER) line)
-1. Jump the SCS line with the HDS, and wait more than 1 minute.
- 2. Disconnect the following connector.
Gauge control module connector A (32P) - 3. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Gauge control module connector A (32P): disconnected 12 volt battery fan motor 3P connector: disconnected Test point 1 12 volt battery fan motor 3P connector (male terminals) No. 2: Test point 2 Gauge control module connector A (32P) (female terminals) No. 24: Is there continuity?
YES
The LIN(METER) wire is OK. Go to step 6.
NO
Repair an open in the LIN(METER) wire between the gauge control module and the 12 volt battery fan motor.
- 12 volt battery fan motor check (substitution)
-1. Substitute a known-good 12 volt battery fan motor.
- 2. Reconnect all connectors.
- 3. Turn the vehicle to the ON mode.
- 4. Clear the DTC with the HDS.
- 5. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC P16E7 PGM-FI-Battery Blower LIN Communication Error Is DTC P16E7 indicated?
YES
Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good PCM - Refer to: PCM Removal and Installation (2014 2015), or PCM Removal and Installation (2016) .
NO
- Fuse check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check the following fuse.
Fuse No. E21 (7.5 A) Location Passenger's under-dash fuse/relay box Is the fuse OK?
YES
The IG1 OPTION wire is not shorted. Go to step 8.
NO
Repair a short in the IG1 OPTION wire between the 12 volt battery fan motor and the No. E21 (7.5 A) fuse. Also replace the No. E21 (7.5 A) fuse.
- Open wire check (IG1 OPTION line)
-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 fan motor 3P connector: disconnected Test point 1 12 volt battery fan motor 3P connector (male terminals) No. 3: Test point 2 Body ground Is there battery voltage?
YES
The IG1 OPTION wire is OK. Go to step 9.
NO
Repair an open in the IG1 OPTION wire between No. E21 (7.5 A) fuse in the passenger's under-dash fuse/relay box and the 12 volt battery fan motor.
- Open wire check (BATT FAN GND line)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode 12 volt battery fan motor 3P connector: disconnected Test point 1 12 volt battery fan motor 3P connector (male terminals) No. 1: Test point 2 Body ground Is there continuity?
YES
Replace the 12 volt battery fan motor .
NO
Repair an open in the BATT FAN GND wire between the 12 volt battery fan motor and G402.
