When the engine is turned off, it can control the operation of the electric fuel pump, control the operation of a certain solenoid valve or relay (such as cooling fan relay, air conditioner compressor relay, etc.), control the fuel injection of a certain fuel injector, etc. After the corresponding control command is issued, if the fuel pump does not rotate (no running sound can be heard), the solenoid valve does not work (there is no vibration when touched by hand), the cooling fan or the air conditioner compressor does not rotate, it means that the actuator or Its control circuit is faulty.

The actuator action test items supported by different car testers are not the same, some support more test items, some support less test items, mainly depends on the software program and matching relationship between the tester and the car ECU.

1. Programming match

Programming matching means that after the working parameters of the electronic control system are changed or new control components are replaced, the vehicle tester is used to communicate with the ECU of the electronic control system, and the system or the newly replaced components are matched with the control system by setting the working parameters. process, also known as initial setup.

Programming matching must have detailed technical information to operate, mainly used for idle speed setting, electronic throttle setting, code setting after replacing various electronic control units, anti-theft function setting, automatic light setting, automatic transmission maintenance subsequent settings, etc. With the development of automotive electronic control technology and the improvement of control precision, more and more programming matching work is required, especially after replacing new control components for Volkswagen series cars, most of them need programming matching.

2. Fault self-diagnosis test tool

There are three types of fault self-diagnosis test tools commonly used in automotive electronic control systems: jumper wires, coders and fault detectors. Car fault detectors are fully functional and easy to use, but expensive. In order to make it easier for users who do not have a fault detector to diagnose faults by reading fault codes, some automobile manufacturers have provided software programs in automotive ECUs that use jumper wires or coders to read fault codes. After connecting with the corresponding wiring terminal on the diagnostic socket, the fault code can be read out according to the flickering status of the fault indicator light on the combined instrument panel or on the codec. After the second generation of on-board fault diagnosis system (OBD-II) was adopted uniformly in 1994, because the global automobile manufacturers unified the fault diagnosis socket form (that is, the standard 16-terminal diagnostic socket) and the common standard for fault test software (that is, the The fault test software of different models can be used in different fault detectors), so the cars produced after 1994 generally need to use the fault detector for self-diagnosis test.
