OBDEMOTO MST3003 Circuit repair kit manual
This product is an electrician combination kit, designed to provide circuit maintenance personnel with a more comprehensive use of tools to facilitate work and improve work efficiency.

Use a slinger to puncture the two wires of the corresponding injector and connect the test lamp.

Main analog pressure sensor types: pressure sensors: rail pressure sensors, oil pressure sensors, intake pressure sensors, urea pump pressure sensors, etc.
The analog pressure sensor is used as shown in the figure below. The positive and negative electrodes can be exchanged during use. The middle line must be connected to the signal line;

After the connection is completed, the voltage of the rotary knob signal line will change between 0-5V to determine the quality of the line.
When simulating the temperature sensor, only 2 lines are used: the positive and signal can be used, and the signal and negative can be used.
Main analog temperature sensor types: water temperature sensor, intake air temperature sensor, oil temperature sensor, fuel temperature sensor, urea tank temperature sensor, liquid level sensor, post-treatment exhaust temperature sensor, etc.
After the connection is completed, the voltage of the rotary knob signal line will change between 0-5V to determine the quality of the line.
Other guidelines for the use of fuses and resistors are not described here, please refer to the vehicle's service manual.
