- poor-quality adjustment;
- malfunctions in hydraulic or mechanical systems;
- malfunctions in the computer or the electrical circuit of the computer.
First of all, check the level and condition of the oil in the gearbox and adjust the linkages.
After driving to warm up the transmission, check the fluid level in the transmission.
Check engine idle speed.
Check the freedom of movement of the accelerator cable and, if necessary, adjust it.
Check the operation of the gear selector mechanism.
In the event of a malfunction in one of the following elements that ensure the normal operation of the automatic transmission (automatic transmission), the indicator lamp for the N position of the selector lever starts flashing. In this case, check the DTCs.
Elements, the malfunction of which causes the lamp of the position N of the automatic transmission selector lever to flash:
- engine crankshaft speed sensor;
- input shaft speed sensor;
- output shaft speed sensor;
- one of the solenoid control valves;
- shift timing mismatch.
Attention: If the N·mode indicator lamp flashes twice as fast, this means that the temperature of the working fluid in the automatic transmission is too high.
Stop the vehicle and wait until the N·mode warning light goes off.
Fault codes are read using a special device, or using the N position lamp of the gear selector lever.
