cell phone jammer has the good cooling system

Three basic method of fault diagnosis? cell phone jammer can block the cell phone band or GPS band simultaneously.  External inspection of the survey to the owners of fault diagnosis of the basic procedures according to prescribed procedures for the transfer of fault code fault code and fault phenomena is obvious, prompt diagnosis fault code fault code, fault is not obvious, according to the intermittent fault diagnosis display normal code, but the failure phenomenon is obvious, trouble-free fault diagnosis fault code for the transfer of vehicle self-diagnostic system for the transfer of the fault code fault indicator on the dashboard disk flashing the law to read fault codes (Toyota, Honda part of GM, Ford and Chrysler cars car) use the multimeter pointer swing laws or self-diode lights flashes law read fault codes (Mitsubishi, Hyundai, Mercedes, BMW) use of the electronic control unit on the red, green light-emitting diode lights flashes law to read the fault code (Nissan) car monitor to read the fault code fault code (GM, Cadillac) fault code retrieval of fault diagnostic apparatus for the transfer of the first generation of vehicle diagnosis system ( the OBD-I) car, you must use special instruments and special instruments, and the diagnosis of a dedicated transmission line and the car seat docking to obtain fault code. cell phone jammer has the good cooling system with wind slots in both sides.Second-generation vehicle diagnostic system (OBD-II) vehicles, with a unified fault diagnosis Block and unified fault code, just an instrument for the transfer of the automobile manufacturing company vehicle fault codes. Intermittent fault diagnosis of intermittent faults: intermittent failure: susceptible to external factors (such as temperature, moisture, vibration, etc.), sometimes there, sometimes they go away failure. The diagnosis of such faults can be simulated fault conditions and environment, so that failure can be reproduced. : Vibration method: vibration method: line is bad or component installation is not strong induced failure. Heating method: heating method: malfunction in the engine temperature is high. Water washout method: water washout method: only the failures in the rain, car wash or high humidity. All appliances connected to France: electrical all connected to the law: the electricity load is too large and cause of failure. cell phone jammer has the built-in design. Road Test method: Road Test method: only failure in the specific driving conditions. Trouble-free fault diagnosis? Fault code fault fault code fault: refers to the use of the vehicle, there is obviously the fault phenomena, but the fault does not light, according to prescribed procedures for the transfer of the fault code, the normal code is displayed. Step to check the contents of normal is not normal approach procedures when charging or battery replacement engine does not work, check the battery voltage is not less than disk transfer engine check the crankshaft whether the rotation to start the engine checks whether the start to check the air Filter element is dirty or damaged check engine idle checks on engine ignition timing, check the fuel system pressure check the spark plugs and high-voltage flashover situation can be turned to good starting filter good idling diagnosis of the fault diagnostic order form "directly to Step 7 Check the clean or replace the filter to accurately adjust the pressure to normal spark ignition timing normal check to rule out the fuel system troubleshooting to rule out the ignition system fault fault diagnosis table? diagnosis of the fault diagnosis sequence table in the electronic control system fault diagnosis according to the fault code tips or trouble-free code, through basic?cell phone jammer has the function of nonstop working.  examination can not identify the cause of the malfunction can be checked in accordance with the fault diagnosis based on fault phenomena. Four circuits and electronic control components fault diagnosis?
