DTC U0104, U0114, U0122, U0131, U0151, U0155, U1101, U129E (16-18 PGM-FI System: 9-Speed A/T (Without CAN Gateway))

NOTE: 

• Before you troubleshoot, review the general troubleshooting information - Refer to: How to Troubleshoot the Fuel and Emissions Systems .
• Before disconnecting the SRS unit connector, do the 12 volt battery terminal disconnection procedure and wait for at least 3 minutes.
• Refer to the DTC code shown on the display, and then inspect the connectors and terminals based on the instructions in the table below.
• The DTC may be stored due to the grounding failure or the power source failure at the transmitting control unit.

  (the grounding inspection and the power source inspection on each control unit are required prior to this checking process)

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.

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

   DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
   U0104 F-CAN Malfunction (PCM-ACC Unit/ACC Unit/Multipurpose Camera Unit)
   U0114 F-CAN Malfunction (PCM-i-VTM Control Unit)
   U0122 F-CAN Malfunction (PCM-VSA Modulator-Control Unit)
   U0131 F-CAN Malfunction (PCM-EPS Control Unit)
   U0151 F-CAN Malfunction (PCM-SRS Unit)
   U0155 F-CAN Malfunction (PCM-Gauge Control Module)
   U1101 F-CAN Malfunction (PCM-ACM)
   U129E F-CAN Malfunction (PCM-Power Control Unit (PCU))

   Are any of the DTC's listed 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 transmitting control units, and the PCM.

   If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot - Refer to: How to Troubleshoot the Fuel and Emissions Systems .

2. Open wire check (F-CAN A_L, F-CAN A_H lines)

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

   - 2. Disconnect the receiving control unit connector.

   NOTE:  Short the SCS to the ground when removing the PCM connector (s).

   PCM connector A (51P)

   - 3. Disconnect the transmitting control unit connectors.

   (Refer to the DTC code shown on the display, and then disconnect the connector (s) based on the instructions in the table below.)

   • Multipurpose camera unit 20P connector
   • i-VTM control unit 24P connector
   • VSA modulator-control unit 38P connector
   • EPS control unit connector B (8P)
   • SRS unit connector A (39P)
   • Gauge control module 32P connector
   • Engine mount control unit 16P connector
   • Keyless access/TPMS control unit connector C (20P)

   - 4. Check for continuity between the receiving control unit and the transmitting control unit on the F-CAN A_H circuit and the F-CAN A_L circuit.
