DTC Logic
DTC DETECTION LOGIC
| DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
| U0100 | Lost Communication With ECM/PCM "A" | When the ignition switch is ON, TCM is unable to receive the CAN communications signal from ECM continuously for 2 seconds or more. |
|
DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn the ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
- Start engine and wait for at least 5 seconds.
- Check the DTC.
Is "U0100" detected?
YES >> Go to TM, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
For the diagnosis procedure, refer to LAN, "Trouble Diagnosis Flow Chart".
