Signál rychlosti vozidla

[Petr147]

tak jsem se zas koukal na diagnostiku a mám tam zas:
U1706 - Síť CAN (NCM - NFR)
P0500 - Signál rychlosti vozidla

na diagnostice mi nesedí KM s počítadlem u budíků a časem se rozdíl zvětšuje... to je to čidlo na převodovce? http://autokelly.cz/#PATH=3761801;17656 ... ST=0|LNG=0|

poslední dobou řeším, že auto divně jede, kolega má Focus a tam když mu odchízelo čidlo, tak chcíply budíky a auto začalo divně táhnout, stačiko sundat nohu z plynu a čidlo se zas chytlo... tady se mi to nijak neprojevuje

What does this mean?
OBD Code P0500refers to
Basically this means that the vehicle's speed as read by the Vehicle Speed Sensor (VSS) is not working properly.
Symptoms
Possible sumptoms of OBD code P0500
loss of anti-lock brakes the "anti-lock" or "brake" warning lamps on the dash may be lit the speedometer or odometer may not work properly (or at all) your vehicle's RPM limiter may be decreased the shifting of an automatic transmission may become erratic other symptoms may also be present
Causes
Possible causes of OBD code P0500
A code P0500 may mean that one or more of the following has happened: The Vehicle Speed Sensor (VSS) is not reading (functioning) properly There is a broken/frayed wire leading to the vehicle speed sensor The vehicle's PCM is not correctly configured for the actual tire size on the vehicle
Possible Solutions
The simplest thing to do is to reset the code and see if it comes back. Next, check all wiring and connectors that lead to the speed sensor. The location of the sensor depends on your vehicle. The sensor could be on the rear axle, transmission, or perhaps the wheel hub (brake) assembly. If the wiring and connectors are OK, then check the voltage at the speed sensor. Again, the exact procedure wil depend on your make and model of vehicle. If everything looks OK, replace the sensor.

takže jestli to chápu dobře, tak to nemusí být čidlo na převodovce, ale může za to třeba ABS...

P0500 is Vehicle Speed Sensor Malfunction. P0xxx codes tend to be standard across the OBD range.

U1706 might be CAN Network (NCM - NFR)

where NCM = Engine Management ECU and NFR = ABS ECU

But U codes are harder to decipher as they tend to manufacturer specific.
