Shift solenoid valves A and B are turned ON or OFF by the TCM in
response to signals sent from the PNP switch, vehicle speed and
throttle position sensors. Gears will then be shifted to the optimum
position.

DTC Confirmation ProcedureECS00CSO
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and wait at
least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Start engine.
3. Drive vehicle in D position and allow the transmission to shift 1
→ 2 → 3 (“GEAR”).
4. If the check result is NG, go to AT- 3 5 9 , "
