Function Explanation (DTC Detection Outline)
• If there is communication error between the A/F signal control driver and the CPU, the PCM stores a DTC.
Repeatability Verification Procedure
1. Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
2. Start the engine and leave it idling for 1 min.
-
Note
-
• Match the engine coolant temperature in the recorded freeze frame data/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.
3. Try to reproduce the malfunction by driving the vehicle for 5 min based on the values in the freeze frame data/snapshot data.

PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM
• 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 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, replace the PCM and perform the repair completion verification.
|
|
No
|
Go to the next step.
|
||
|
Repair completion verification
|
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.
