DTC 62
CIRCUIT DESCRIPTIONShifting from 1st to O/D is performed in combination with ON and OFF of the No. 1 and No. 2 solenoid valves controlled by ECM. If an open or short circuit occurs in either of the solenoid valves, the ECM controls the remaining normal solenoid to allow the vehicle to be operated smoothly (Fail safe function).
Fail Safe Function
If either of the solenoid valve circuits develops a short or an open, the ECM turns the other solenoid ON and OFF to shift the gear positions shown in the table below. If both solenoids malfunction, the hydraulic control is not made electronically and can only be operated manually.
Manual shifting as shown in the following table must be done. (In the case of a short circuit, the ECM stops sending current to the short circuited solenoid).
X: Malfunctions
Check the No. 1 solenoid when diagnostic code 62 is output and check the No. 2 solenoid when diagnostic code 63 is output.
