U255U Daihatsu U4 OBD Code

OBD/2 U255U error code description and symptoms.

Vehicle Speed Sensor (VSS) Intermittent Indicates the powertrain control module (PCM) detected an error in the vehicle speed information. Vehicle speed data is received from either the vehicle speed sensor (VSS), transfer case speed sensor (TCSS), anti-lock brake system (ABS) control module, generic electronic module (GEM), or central timer module (CTM). This DTC is set the same way as U255U. However, it is intended to flash the transmission control indicator lamp (TCIL) for first time VSS circuit error/malfunctions. Refer to possible causes for U255U

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U255U, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U255U on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.

U255U Daihatsu U4 Error Code Repair Process :

The rule of U255U code when it comes to emissions-related vehicle repair is that any modification that changes the vehicle from a certified configuration to a non-certified configuration is considered tampering: this applies to both vehicle owners and repair facilities and is, therefore, a Federal offense. Replacing a catalyst with a straight pipe is one traditional example of air suspension rr height sensor circuit short to ground. Likewise, overriding the OBD U255U error in system through the use of high-tech defeat devices or non-certified computer chips, for example, would also be considered tampering. The OBD system may, however, be repaired back to its original certified configuration with certified performance chips or appropriate aftermarket parts.

Common Causes of Daihatsu U4 U255U OBD2 Code

A common cause of code U255U is the failure of Air Suspension RR Height Sensor Circuit Short To Ground, but there are several other possible causes as well, such as ;

EVAP system hose leaking
Faulty Air fuel ratio (A/F) Sensor 1 Bank 1
Incorrect Positive Crankcase Ventilation (PCV) hose connection
Intake Valve Timing Control Solenoid Valve circuit poor electrical connection

U255U 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.
