Step 1: Determine the cause
* Read trouble codes using an OBD-II scanner. This will help determine the root cause of the emergency mode.
Step 2: Eliminate the cause
* Once the root cause is determined, correct it accordingly. This may include:
* Replacement of a faulty sensor or solenoid
* Adjusting the transmission fluid level
* Repair of mechanical components
Step 3: Reset your computer
* After eliminating the cause, disconnect the negative battery cable for 10-15 minutes.
* This will reset the automatic transmission computer and allow it to relearn operating parameters.
Step 4: Restart the engine
* Restart the engine and let it idle for 5-10 minutes.
* The automatic transmission computer will recalibrate and exit emergency mode.
Step 5: Check
* Drive the car and check whether the automatic transmission switches back to normal operation.
Additional tips:
*If the trouble codes do not show a clear cause, try resetting the computer first.
*If the problem persists, contact a qualified mechanic for further diagnosis.
* Avoid driving in limp mode as this may cause further damage to the automatic transmission.
Precautions:
* Before disconnecting the battery, turn off the ignition and set the parking brake.
* Be careful when reading trouble codes to avoid damaging the scanner.
*Always consult your vehicle’s owner’s manual for specific instructions.
