Code No. 36, 52 Damper clutch control solenoid valve
system Probable cause
If the resistance value for the damper clutch control solenoid valve is too large or
too small, it is judged that there is a short-circuit or an open circuit in the damper
clutch control solenoid valve and diagnosis code No. 36 is output. If the drive duty
rate for the damper clutch control solenoid valve is 100 % for a continuous period
of 4 seconds or more, it is judged that there is an abnormality in the damper clutch
control system and diagnosis code No. 52 is output. When diagnosis code No. 36
is output, the transmission is locked into 3rd gear as a fail-safe measure, and the
N range lamp flashes at a frequency of 1 Hz.
