DTC Confirmation ProcedureINFOID:0000000005928806
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
2. Start engine and maintain the following conditions for at least 12 consecutive seconds. ACC PEDAL OPEN: More than 1.0/8
RANGE: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
3. If DTC is detected, go to CVT-78, "
Diagnosis Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
