Vehicle status when DTCs are output
• Not applicable
Possible cause
• BARO sensor (built-into PCM) malfunction
• PCM malfunction



System Wiring Diagram

• Not applicable



Function Explanation (DTC Detection Outline)

• If there is a communication error between the BARO sensor and the CPU or a malfunction in the non-volatile memory inside the BARO sensor, the PCM stores a DTC.

Action

1
PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
• Verify related Service Bulletins, on-line repair information, or Service Information availability.
• Is any related Information available?
Yes
Perform repair or diagnosis according to the available information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the freeze frame data/snapshot data.

Note
• Recording can be facilitated using the screen capture function of the PC.
Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.



Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
• Step 1
― Perform a unit inspection of the BARO sensor.
• Repair completion verification
― Verify that the primary malfunction is resolved and there are no other malfunctions.

Action

1
PURPOSE: INSPECT BARO SENSOR FOR MALFUNCTION
• Is the part normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
Repair completion verification 1
PURPOSE: VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
― Perform the KOEO or KOER self test. (See DTC INSPECTION.)
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1.
No
Go to the next step.
Repair completion verification 2
PURPOSE: VERIFY IF OTHER DTCs DISPLAYED
• Perform the DTC inspection. (See DTC INSPECTION.)
• Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
