Check 1 (program selector)
Check 2 (reversing light control)
Check 3 (audible signal that the lever must be moved to the "P" position (ignition key lock)

Check 4 (oil temperature too high)
If the oil temperature exceeds the limit value of 118°C: the "Snow" and "Sport" indicators flash. Make sure that the heat exchanger solenoid valve is not shorted to "+".
Read the parameters of the diagnostic device: "Excessively high oil temperature".
Emergency mode:
- gear shifting at minimum speed and immediate locking of the torque converter
- the "Sport" and "Snow" indicator lights stop flashing as soon as the temperature becomes < 118°C.
Check 5 (pressure regulation error)
"Sport" and "Snow" indicator lights flash: yes.
There are two possible reasons!:
- malfunction associated with auto-adaptive values of pressure in the line in the ECU memory;
- a malfunction associated with an error in the control circuit, i.e. an increase in the difference between the calculated and measured pressure in the line.
Check:
- oil level;
- operation of the pressure modulation solenoid valve;
- oil pressure sensor.
Emergency mode:
- switching to emergency operating mode!;
- set line pressure to maximum;
- open loop control.
Check 6 (lock error - not EVM lock)
The ECU has detected clutch slippage.
Emergency mode: no locking functions when stopped.
Check 7 (launch permission)
Check 8 (diagnostic line)
