U053C Rolls-royce Legalimit OBD Code

OBD/2 U053C error code description and symptoms.

Low Speed Fuel Pump Primary Circuit Malfunction The PCM monitors the low speed fuel pump (LFP) primary circuit output from the PCM.
The test fails if: When the LFP circuit is commanded on (grounded), excessive current draw is detected on the LFP circuit; or when the LFP circuit is commanded off, voltage is not detected on the LFP circuit (the PCM expects to detect VPWR voltage coming through the low speed fuel pump relay coil to the LFP circuit). Open or shorted low fuel pump (LFP) circuit Open VPWR to low speed fuel pump relay Damaged low speed fuel pump relay Damaged PCM An open circuit or short to ground can only be detected with the low speed fuel pump.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U053C, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U053C on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

If your engine rpm output circuit malfunction check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U053C and engine control unit are in charge of monitoring a bunch of different engine rpm output circuit malfunction, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Rolls-royce Legalimit U053C OBD2 Code

A common cause of code U053C is the failure of Engine RPM Output Circuit Malfunction, but there are several other possible causes as well, such as ;

EVAP canister or fuel tank leaks
Faulty TCM or TCM programming
Fuel Injectors circuit poor electrical connection
Variable Valve Timing (VVT) circuit is open or shorted

U053C is a kind of Network Trouble Code

U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.
