MODES
AND
MODE
CHANGING
Sensors can have many different “modes” when they have been read, such as Learn, Tool LF, YD Sleep, YD Rest, Hi Norm
Dly. Some of those are called sleep mode to preserve battery life.
Mostly, these modes are not important because the sensor will be supplied already in the correct mode to use. But for
some sensors made by Continental it is important that the mode is displayed as “Park,” as otherwise it will not work on
the vehicle.
The TECH550 tool can perform the necessary mode change. If a sensor is shown as “Ship,” “Test” or “Off” and the relearn
toolkit provides the option “Set Sensor to Park Mode,” please use this option to change the sensor mode into the correct
one:
•
Go to “Relearn” and select vehicle (MMY).
•
Press enter when relearn procedure shows.
•
Select the spanner in the upper left corner with the Up/Down buttons. Press Enter.
•
Select “Set Sensor to Park Mode”, press Enter.
•
Go to the wheel, hold the tool near the sensor and press “Test”.
•
Repeat for each wheel.
•
Start the Relearn procedure.
Also, some sensors are supplied in a mode where they cannot be read by the tool unless they are pressurized in a wheel.
Some examples would be replacement sensors bought from a Ford dealership, and some Mitsubishi Continental sensors.
