Hallo,
ich hatte bei mir alle Faults gelöscht, tested und not tested, dann
nach einigen Fahrten wieder ausgelesen...
keine Fehler unter "Tested", schon mal gut.
Aus Neugierde habe ich natürlich auch die nicht getesteten ausgelesen...
Hier gab es dann wieder einige
U3000
B1A75
B1A81
U0401
U2101
P0404
P1602
Da sie alle nicht getestet sind mache ich mir erstmal keine Gedanke..., kennt jemand diese codes und deren Ursache...
Grüße
Thomas
Schein in der Tat, als wäre jeder Landy ein Unikat...
hier mal was Grundsätzliches zu Fehlercodes (Quelle defender.net):
Thought I would try and explain the differences in DTC codes. So here goes:
There are basically two types of DTC codes for OBDII Diagnostics:
Emissions related DTC'sTested DTC's Type A
1. Emissions related. 2. The Malfunction Indicator Lamp (MIL) will be illuminated as soon as the error occurs. 3. Stores a freeze frame DTC after one failed driving cycle.( history DTC is stored )
Type B
1. Emissions related. 2. Sets a Pending Trouble Code after one failed driving cycle. 3. Clears a Pending Trouble Code after one successful driving cycle. 4. Turns on the MIL after two/three consecutive failed driving cycles. 5. Stores a Pending Trouble Code as a DTC after two consecutive failed driving cycles.
Conditions for Clearing the MIL/DTC – Type A or Type B
The MIL will turn off after four consecutive driving cycles in which the diagnostic runs without a fault. A history DTC will clear after 40 consecutive warm up cycles without a fault. DTC(s) can be cleared by using a scan/diagnostic tool.
Non–Emissions Related DTCsUn Tested DTC's
Action Taken When the DTC Sets
1. The Malfunction Indicator Lamp (MIL) will not illuminate. 2. The ECM will record a DTC at the time the diagnostic fails.
Conditions for Clearing the DTC
A history DTC will clear after 40 consecutive warm up cycles without a fault. DTC(s) can be cleared by using a scan/diagnostic tool.
How to read a DTC Code
The DTC value will help you narrow down the specific component or module in question. A DTC has a standardized format that can be interpreted as follows: The first part of the DTC is the Alpha Designator. The alpha designator will be:
B - Body electronics (i.e., door and hood latches) C - Chassis (i.e., traction control or ABS) P - Powertrain (i.e., engine, transmission) U - Network communications for the different control modules
Second Digit - Code Type The second digit identifies whether the code is a generic code (same on all OBD-II equpped vehicles), or a manufacturer specific code.
0 = Generic (The diagnostic codes that are required by law on all OBD II systems are "generic" in the sense that all vehicle manufacturers use the same common code list and the same 16-pin diagnostic connector. Thus, a P0301 misfire code on a Ford means the same thing on a Vauxhall, Citroen, Toyota or Mercedes.)
1 = Enhanced ( Each vehicle manufacturers also have the freedom to add their own "enhanced" codes to provide even more detailed information about various faults. Enhanced codes also cover non-emission related failures that occur outside the engine control system. These include ABS codes, HVAC codes, airbag codes and other body and electrical codes.)
Third Digit - Sub-System
The third digit denotes the type of sub-system that pertains to the code
1 = Emission Management (Fuel or Air) 2 = Injector Circuit (Fuel or Air) 3 = Ignition or Misfire 4 = Emission Control 5 = Vehicle Speed & Idle Control 6 = Computer & Output Circuit 7 = Transmission 8 = Transmission 9 = SAE Reserved 0 = SAE Reserved
Fourth and Fifth Digits These digits, along with the others, are variable, and relate to a particular problem code error number
So let's diagnose a DTC, I've picked P0404-73 EGR control circuit range/performance: actuator stuck closed
so we have: P = Powertrain (engine, transmission) 0 = Generic 4 = Emissions control 0 4 =This is the specific error code within Emission control. In this case the EGR control circuit range/performance -73= This is a specific problem, in this case the actuator is stuck closed. 72 means its stuck open.
