There are three main reasons for enabling emergency mode.
Reason # 1: abnormal content of technical fluid in the transmission. These include both high and low levels.
This leads to a malfunction of the ECU, and the automatic transmission goes into stop and lock mode. If there is a lot of liquid, then it needs to be pumped out, if it is not enough, then top up and look for the cause of losses.
The reason for the transition of automatic transmission in emergency mode number 2: incorrect operation of the hydraulic or mechanical component of the box.
In this case, the repair work will save the budget. If the hull or friction kit itself is damaged, it will be necessary to unscrew the pallet and inspect for foreign inclusions and components. If they are available, automatic hardware diagnostics is required, or a detailed inspection of each part.
The reason for the transition automatic transmission in emergency mode number 3 : electrical problems in the control system.
The most common cause
• Failure of the temperature sensor, then the alarm status is turned on permanently, or when the operating temperature is set. • Failure of the electrical network, then the transition to emergency mode occurs randomly and unpredictably. it is necessary in stages and elements to look for the place of interruption of the electrical flow. • Scanning detects breakdowns in the sensors of various elements of the vehicle (ABS, throttle, etc.), then the breakdown mode is activated steadily or unpredictably, but at the same speed.
• If, when switching to the “D” position or from 1 to 2 speeds, a thud implies that the box is in emergency mode, then most likely the instability of the shaft rotation input and output sensors is to blame. This breakdown can also be identified by scanning, and the installation of new sensors will help solve the problem.
• In case of malfunctions in the control unit, the emergency mode is constantly activated and the emergency mode is set, and all actions for switching it to the operating mode are useless. Only a new block is guaranteed to help here, since scanning never gives 100% of the detection of this problem.
