Code No. 41, 42 Solenoid valve No.1 system Probable cause
If the resistance value for a solenoid valve No.1 is too large, it is judged that there
is an open circuit in the solenoid valve No.1 and the diagnosis code No.41 is output.
If the resistance value for a solenoid valve No.1 is too small, it is judged that there
is a short-circuit in the solenoid valve No.1 and the diagnosis code No.42 is output.
D Malfunction of solenoid valve No.1
D Malfunction of harness or connector
D Malfunction of the A/T-ECU
Solenoid valve No.1 check (Refer to P.23-42.)

Code No. 43, 44 Solenoid valve No.2 system Probable cause
If the resistance value for a solenoid valve No.2 is too large, it is judged that there
is an open circuit in the solenoid valve No.2 and the diagnosis code No.43 is output.
If the resistance value for a solenoid valve No.2 is too small, it is judged that there
is a short-circuit in the solenoid valve No.2 and the diagnosis code No.44 is output.
