Check 1 (program selector)
Check 2 (reversing light control)
Check 3 (sound signal to move the lever to the position «R» (ignition key lock)
Check 4 (oil temperature too high)
If the oil temperature exceeds the limit value of 118°C: indicators «Snow» And «Sport» flashing Check that the heat exchanger solenoid valve is not shorted to «+».
Read the parameters! diagnostic tool: «Excessively high oil temperature».
Emergency mode:
- shifting gears at minimum speed and immediate torque converter lockup
- pilot lamps «Sport» And «Snow» stop flashing as soon as the temperature is < 118°C.
Check 5 (pressure regulation error)
Pilot lamps «Sport» And «Snow» flashing: yes.
There are two possible reasons!:
- a malfunction associated with auto-adaptive line pressure values in the ECU memory;
- a malfunction associated with an error in the control loop, that is, 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:
- transition to emergency operation is in progress!;
- setting line pressure to maximum;
- open loop control.
Check 6 (lock error - not EVM lock)
The ECU has detected a clutch slip.
Emergency mode: no blocking functions when stopped.
Check 7 (launch permit)
Check 8 (diagnostic line)
