DTC CONFIRMATION PROCEDURE

CAUTION:
Always drive vehicle at a safe speed.

NOTE:
If "DTC CONFIRMATION PROCEDURE" has been previously performed, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select "Data Monitor" in "TRANSMISSION".
3. Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.

MMODE : On

Is "P0826" detected?
YES - Go to P0826.
NO - Check intermittent incident. Intermittent Incident.




Diagnosis Procedure
Regarding Wiring Diagram information, [1][2]Electrical Diagrams.
1.CHECK MANUAL MODE SWITCH SIGNALS
With CONSULT-III
1. Turn ignition switch ON.
2. Select "Data Monitor" in "TRANSMISSION".
3. Check the On/Off operations of each monitor item.





Without CONSULT-III
Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the position mutually coincide when the selector lever and paddle shifter* are shifted to the "+ (up)" or "- (down)" side (1st from/to 6th gear).
