Reasons for activating emergency automatic transmission mode in Mitsubishi Lancer
The emergency mode of the automatic transmission (automatic transmission) is activated when the electronic control unit (ECU) detects a malfunction in the transmission. The main reasons for its activation on the Mitsubishi Lancer:
*Low or contaminated transmission fluid
* Faulty solenoids or valves
* Mechanical faults (for example, wear of clutches or planetary gear)
* Electrical faults (such as open or short circuit in the wiring)
* Problems with sensors (such as input shaft speed sensor or engine speed sensor)
Symptoms of automatic transmission emergency mode activation:
* Reducing engine speed when changing gears
* Increased gear shift times
* Jerks or jolts when changing gears
* Limitation of gear selection (usually only 2-3 gears available)
* Appearance of the “check engine” indicator on the dashboard
Actions of the driver when the emergency mode of the automatic transmission is activated:
* Pull over to the side of the road and stop the car.
* Check the level and condition of the transmission fluid. If necessary, add fluid or contact a service center.
* Turn off and turn on the engine again. In some cases, this may reset the emergency mode.
*Go to the service center. Drive in emergency mode only for short distances, as this may cause further damage.
Troubleshooting:
Troubleshooting will depend on the specific reason for activating the emergency mode. Typically the following steps are required:
* Replacement of transmission fluid and filter
* Diagnose and replace faulty solenoids, valves or sensors
* Mechanical repair of automatic transmission (for example, replacement of clutches or planetary gear)
* Repair or replacement of electrical wiring
It is important to promptly correct the malfunction that led to the activation of the emergency mode in order to prevent more serious damage to the transmission.
