Further calculation Launch X431 V wifi Bluetooth can get the fuse resistance of 20.9mV / 12.0A = 0.0017Ω, because the characteristics of the car circuit is a high current, so we can detect the micro voltage drop can find the current flow path.

(1) The module is an integral part of the Launch x431 v electronic control system of the in-cylinder injection engine. Its main function is to provide different power supply load regulation to the gasoline pump in order to prolong the life of the gasoline pump and save the energy according to the needs of the engine oil supply. Reduce noise.

(5) This fault is a launch x431 diagnostic tool more common fault, and this module is widely used, in addition to the new Passat, the MAGOTAN, Sagitar and other in-cylinder injection of the engine are equipped with this module, the fault is typical and representative....

4S shop after the car, the vas 6154 diagnostic tool maintenance personnel that the fault car for routine inspection, for the tightening, heavy failure to reproduce the test, the results as described by the customer. In the inspection found: the car EPS system is the main parts of the new pieces, the customer told the car a month ago to replace the steering system assembly, including torque sensors and booster motor, but still do a regular check.

First read the EPS self-diagnostic system fault information. Because the EPS has a fault self-diagnostic function, if the sensor, ECU or actuator fails, the EPS fault indicator on the dashboard is always on and the fault code is stored in the EPS ECU.

Launch x431

At the same time, to stop the power to help the steering system to restore the gear to the mechanical steering function and lead to heavy steering. Use the HDS diagnostic device dedicated to the HONDA launch x431 v 8 inch sedan for fault diagnosis: place the ignition switch in the "OFF" position, connect the HDS diagnostic instrument to the diagnostic interface below the dashboard, set the ignition switch to "ON" position, turn on the diagnostic instrument, Follow the instructions in the DTC Diagnostics menu of the HDS Diagnostic Chassis Fault to read the DTC 12-torque sensor circuit fault or poor contact.

Then use the HDS diagnostic instrument to delete the fault code, delete the fault code, lift the vehicle to leave the ground, about the maximum limit turn steering wheel observation and found that the EPS xtool x100 fault light does not shine, the vehicle is vas6154 not driving state, EPS returned to normal.

Therefore, the vehicle will be delivered to customers. The next morning, the customer in turn the fault car to the 4S shop to rebuild, reflecting the car in a stone road driving vibration was severe, in the direction of the emergence of EPS fault lights often bright, turned heavy.
