The Electronic Control Unit (ECU) is the brain of a modern vehicle, responsible for managing and controlling various aspects of the engine's performance.

The 128 means that the fault is broadcasted from the engine. If these faults are being read from the dash display, a lot of the times that gives incomplete information as to the actual fault that is being sent out. In which case the faults must be read by a pc program or capable scanner.

On the Mercedes Freightliner Sprinter engine, ECU 128 is not a fault code; it just refers You to the electronic control unit, where Your fault code will lie.

What Are Some Causes of a P0128 Code? Error code P0128 indicates that your engine coolant temperature is below the thermostat regulating temperature. This means that your Engine Control Module (ECM) or Powertrain Control Module (PCM) has recognized that your engine is running cooler than it's supposed to.

Inspect Wiring and Connections: Often, electrical problems can cause ECU issues. Check for loose or damaged wiring, corroded connections, and any visible signs of damage. Battery Check: Make sure the battery is in good condition and has sufficient charge. A weak or dying battery can cause erratic behaviour in the ECU.

The engine control module does what its name suggests: It controls the engine. If the ECM has died completely, you won't be able to start your car. Your engine could cut while you're driving, as well, if the ECU malfunctions. Once you've coasted to a stop, you won't be able to get your automobile started again.

ECU repairs can be very expensive. The part alone can cost between $1,000 and $3,000, depending on the make and model of your vehicle. Fortunately, an ECU can be repaired or reprogrammed in many cases—thus preventing the need to actually replace an ECU.

Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1.

Use Code 128 Auto whenever possible. This setting will encode your data with the shortest possible number of bars by mixing Subset A B and C as necessary. Control characters, such as TAB or NEW LINE, may be encoded by entering their three digit ASCII code prefixed by a caret (^).

Code 128 is a compact linear barcode originally developed in 1981. Its high data density and ability to encode extensive product information makes it popular for use in logistics, healthcare, transportation (particularly shipping) and retail.

Turbocharger compressor inlet temp circuit failed high. This could be a wiring or connection issue, or a failed sensor.

The electronic control unit (ECU) used in today's cars and trucks is used to control the engine and other components' functions. An ECU is a computer with internal pre-programmed and programmable computer chips that is not much different from a home computer or laptop.

The two most common causes of the P0601 error code are that the ECM (or ECU) is failing or has failed or that the ECM/ECU is receiving low voltage. The P0400 error code is defined as an Exhaut Gas Recirculation Flow Malfunction.

Code P0660 stands for “Intake Manifold Tuning Valve Control Circuit Open/Open Bank 1.” It's logged when there's a mechanical or electrical fault in the intake manifold tuning valve located in Bank 1 or when the valve is stuck or contaminated.

Diagnostic Trouble Code (DTC) P2101 stands for Throttle Actuator “A” Control Motor Circuit Range/Performance. It is usually triggered when your vehicle's powertrain control module (PCM) detects that the actual throttle position does not match the desired throttle position.

The P2015 code refers to the intake manifold runner control (IMRC) system. Most of the time, this is for bank 1, which sits on the same side of the engine as the first cylinder. If your engine is an inline engine, then your vehicle will only have one bank, and this code will indicate a problem with the single bank.
