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. CHECK DTC DETECTION

1.Turn ignition switch ON.
2.Shift the selector lever to the entire position from P to 1. (Hold the selector lever at each position for 10
seconds or more.)
3.Check the first trip DTC.
Is "P0705" detected?
YES- Go to "Diagnosis Procedure" .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK TCM INPUT SIGNALS

With CONSULT
1.Turn ignition switch ON.
2.Select "TRANSMISSION" "DATA MONITOR".
3.Select the "D position switch", "N position switch", "R position switch", "P position switch", "2 position switch", and "1 position switch".
4.Shift the selector lever to the entire position from P to 1, and check the ON/OFF operation of each monitor item.










Without CONSULT.
1.Turn ignition switch OFF.
2.Disconnect the TCM connector.
3.Turn ignition switch ON.
4.Shift the selector lever to the entire position from P to 1, and check the voltage between the TCM harness connector terminal and ground.





Is the check result normal?
YES - Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
NO-1 [D position SW is "On" when selector is not in D position. (Or, connector terminal 4 is at 10 - 16 V.)]GO TO 2.
NO-2 [N position SW is "On" when selector is not in N position. (Or, connector terminal 5 is at 10 - 16 V.)]GO TO 4.
NO-3 [R position SW is "On" when selector is not in R position. (Or, connector terminal 6 is at 10 - 16 V.)]GO TO 6.
NO-4 [P position SW is "On" when selector is not in P position. (Or, connector terminal 7 is at 10 - 16 V.)]GO TO 8.
NO-5 [2 position SW is "On" when selector is not in 2 position. (Or, connector terminal 3 is at 10 - 16 V.)]GO TO 10.
NO-6 [1 position SW is "On" when selector is not in 1 position. (Or, connector terminal 2 is at 10 - 16 V.)]GO TO 12.
