Continue as follows to ensure that the problem is resolved: There should be no active DTCs in relation to applying voltage to the sensors or battery voltage. Necessary cookies are absolutely essential for the website to function properly. Saving around 10,000 €, lower fuel consumption, more payload—models such as the MAN TGS, Mercedes Axor, Scania G and Volvo FM offer a lot of truck in comparison to their larger siblings, and they make the hearts of shippers and movers beat faster. Scania R420 LA4x2HNA specifications. Switch off the ignition. The engine stops or goes into emergency mode. Recognition of codes invalid can be performed only if: no active trouble code affecting coolant temperature, coolant temperature is approximately 80 ° C. Check the nozzle and the compression in the cylinder. Incorrect handling, for example, incorrectly shifted to a lower gear. Check the coolant temperature sensor electrical connectors and wiring. In the case of engines with EGR, the engine works with EGR, but without any feedback through the mass flow sensor. The signal from the charge-air temperature sensor has an unreliable value. If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. The charge air pressure sensor generates an incorrect value. Tyres comes with truck are width of 12.00 R 20. You can go to the fault code monitoring function and view the fault code. Check back pressure sensor in exhaust system T125, charge air pressure sensor T122 and charge air temperature sensor T121. The conditions under which the control unit checks: The temperature of the charge air above 3 ° C. The difference between the charge air temperature and the outside temperature must be less than 10 ° C for 10 seconds. The voltage in the circuit has fallen below acceptable levels. Engine running unevenly. All three sensors should indicate the pressure corresponding to the current atmospheric pressure. The engine then resumes normal operation if there is no damage. Troubleshoot by comparing the charge-air temperature sensor with the atmospheric pressure sensor and the backpressure sensor in the exhaust system. The engine control unit switches off the exhaust gas recirculation system. While there is a fault, the car cannot start moving. Cylinder 6, Cylinder balance (min. Thanks Given: 15608 Thanks Received: 4043 (663 Posts) Posts: 961 Threads: 87 Joined: Oct 2011 19 02-09-2016, 05:57 PM The But Scania admits that it needs this economy improvement to offset the addition of a diesel particulate filter (DPF), which raises exhaust backpressure and so harms consumption. Coolant temperature has exceeded 104 ° C. This malfunction may be caused by the following reasons: low coolant level, coolant leakage or clogged radiator. The fault code cannot be cleared while the fault is present. Check for leaks in the air supply system or intake manifold. Malfunction affects vehicle emissions of nitrogen oxides (NOx); on the instrument cluster a warning lamp lights up, warning of a high level of pollutants. On engines equipped with an EGR system, the engine control unit will turn off the system. fuel consumption ratings in litres per 100 kilometres (L/100 km). The engines, which are available at 520, 580 and 650 horsepower, can reduce fuel consumption by 7 to 10 percent for customers with vehicles that have higher combined truck and trailer weights, higher average speeds, … Axle alignment, tyre pressure, air deflector adjustment – keep your truck as fuel-efficient as it was on day one, with Scania … Resistance must be infinite. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors. A fault can also be caused by a fault in other sensors with a common power supply circuit. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65. Malfunction in the electrical circuit of the charge air pressure sensor, coolant temperature sensor, fuel line pressure sensor or fan speed sensor. A short to ground in the electrical circuit of the solenoid valve. Malfunction in high pressure pump, fuel metering inlet valve or fuel pressure sensor. The charge air pressure sensor indicates a value higher than the value of the pressure sensor in the exhaust system. Act quick to avoid disappointment Short circuit of the solenoid valve bypassing the turbine on the + battery. Scania offers a wide choice of vehicles. Check the system gas supply and injectors. During the training we focus on how to cut fuel consumption and minimise repair … Make sure the sensor is connected to the correct pin in the engine control unit connector (try changing the polarity). The temperature shown by the outside temperature sensor is too high. The cylinder does not output the same power as the other cylinders for the following reason: The cause may be air in the fuel system, but in this case several cylinders are likely to be affected. At a press conference today in Hanover, Scania… When this DTC is active, engine power is reduced and the EGR system shuts off. Featured Images 3 Gallery Swipe to view more images Tap to open gallery Images (3) Videos 0 Images 3. Adaptation values ​​of the gas mixture reached the upper or lower limit. Turn on the ignition and wait at least 15 seconds. The Injector tuning PowerControl PDX from DTE now increases driving dynamics while reducing fuel costs. We struggle to find drivers for it when the regular drivers (its double shifted ) … If necessary, replace the coolant temperature sensor. Vehicles with a NOx control system also display a text message. Compressed natural gas is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG). Here's all the press material we were sent by Scania on Monday. Diesel consumption Scania, , R420. “We build upon Scania’s vast V8 experience and continue to improve what generations of skilled engineers have learnt, created and achieved before us,” says Göran Lindh, Chief Engineer for Scania’s V8 engines. The fault affects the emission of nitrogen oxides (NOx) by the car, and a warning lamp lights up in the instrument cluster, warning of a high level of pollutants.
