Manual De Bomba Bosch Vp44 Troubleshooting

Print; the instruction of disassembly of a bosch vp30 or vp44 pump driver in order to send it for repair: attention! You do not need to dismantle the whole pump out of your car.

• WHAT TELLS BOSCH VP 30/44 'BRAIN'? Pivot ben 10 ultimate alien package. Bosch VP44 sign dzeladagolja VP29/30 and old acquaintances. There are many manufacturer has applied over the past ten years, passenger cars and diesel engines too, the commercial vehicles through the power of agricultural machinery and diesel engines. Taking advantage of the discharge pipe of the pressure waves being reflected on the waves summation (superposition), reached the porlasztcscsnl create up to 2,000 bar. At this injection pressure (top) helped the old engines (but then the new ones) to meet the environmental standards. Think of the common rail still in its infancy, and the adagolporlasztt - car engine - only the VW group favored.

Ivan Nagy Szokolyai Old acquaintances for a few years - to the delight of staff and losers - become szervizbartabb: well diagnosed each element can be improved. This is due to the fact that correctly answered question, and the answer is largely understood. The Fed is happy about this, because the car mechanics can provide a variety of information before starting repairs. In fact, the car mechanic can tell already that the input to brain-dead.

It is better if the client know as soon as possible. The information kicsalogatsnak and mode of understanding - that the diagnosis - cikknkkel want to contribute. We hope to update knowledge as this will help many people, young people and maybe an old system to a new one can say. 1 illustration The VP29/30 VP44 and the so-called feeders.

Idvezrlsek (solenoid valve), to be added - the feeder house tetere base - their 'brain' (ECU), the German acronym speaking with PSG also have (Fig. A feeder VP name has not been clear that they are time-controlled because there VP 28, VP 33, VP 36 and VP 37, which are lvezrlsek. • 2 illustration The dispenser is the brains of the PSG's (Pumpensteuergert) three types, two of the PSG, the PSG PSG 5 and 16 In the following, we only deal with the PSG version 5, and is simply called a PSG (Fig. The PSG is itself stored fault codes, which - and this is important - the motorECU through not fully readable and therefore more useful diagnosis. The PSG itself - can be tested or dismantled motor fitted on the state-without motorECU. 3 Figure VP44/30/29 The pin assignment: 1 - CAN-H, 2 - CAN-L, 3 - CAN-body 4 - control signal (optional), 5 - switch-off signal (optional), 6 - body, 7 - power supply, 8 - speed signal 9 - K-line (diagnostics) We can diagnose anything?

Examination of the feeder and the PSG provides the following options. 1 Determination of PSG 'agyhallnak.' 2 Analysis of PSG's power. 3 Examination CAN cable between the PSG and the motorECU resistance. 4 DTC reading the PSG.

The error code readout for the PSG for release at immos switching (eg FORD PATS) either! 5 Examination of the engine operating at PSG: 1.5 Checking the CAN connection 2.5 Checking the solenoids (the oscilloscope measurements are not discussed in our article) The PSG pin layout, numbering and identification of the third As shown in Figure • 1 Determination of PSG 'agyhallnak' Always start with the measurements! Stated that 'brain dead' Does PSG or not. Weigh resistance between the PSG 6-inch and 7-inch pins. If you are between 6 and 7 points of resistance from 2.5 to 4.0 k (kilo-ohms), the PSG good (Figure 4).

If you fall outside of this range the resistance, or short- circuited, the PSG is to be replaced! Thus, the 'brain-dead' feeder PSG exchange Fix! If the PSG is shorted connect the Bosch KTS instrument, damage, damage to the Hungarian KTS! 4 illustration 2 Analysis of PSG's power Check the incoming power! The motorECU from reaching the feeder cable bundle - 5 the figure shows the expanded connector - between the power and ground pins, after ignition on, let's see how much of the supply voltage. 12 - should be between 15 V. • 5 illustration 3 Examination CAN cable between the PSG and the final resistance of motorECU Check the value of the terminating resistor of CAN lines!

The dispenser of PSG connector 1 and 2 (Figure 6). Value of 120 (CAN each pair of wires to the value in the final resistance). The engine ECU supply pipe connector 120 value must be between 1 and 2 as well. • 6 illustration 4 DTC reading the PSG The VP30 and VP44 PSG batching controller Bosch KTS reading instrument family, engine mounted and dismounted Tray is possible. In both cases it is advisable to use the BOSCH vizsgladaptert (Prfbox ), which is concluded in series between the input and motorECU (Figure 7).

If you can tie the series vizsgladaptert, the PSG network of the car gets the power. 7 Figure 1, 2, 3 - CAN data bus cables, 4 - control signal (optional) 5 - solenoid shut-off signal (optional), 6 - Body, 7 - power supply, 8 - speed signal transmitter, 9 - K-line (diagnostics) If you are only connected to the feeder (the feeder with lowered engine side connector hangs in the air), or table 'spread' is the input, so we have to feed dries.A fully charged battery can power. Wiring polarity errors in the PSG can not fend off! • Figure 8 The well-stocked initial state is also a must because if programmed and the battery runs out of power while driving, blown so far and also the PSG.
