DESCRIPTION
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.




TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.




ON BOARD DIAGNOSIS LOGIC

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE

CAUTION:
- Always drive vehicle at a safe speed.
- If conducting this "DTC CONFIRMATION PROCEDURE" again, always turn ignition switch "OFF" and wait at least 5 seconds before continuing.
