Re: 2008 Subaru outback 2.5 na

Hi.
If we are talking about the SUBARU EJ25, then a dual coil with a dual ignition switch is installed.
The ignition switch is controlled by applying a rectangular pulse with an amplitude of about +8.4 volts.
When using a 1:10 divider, a signal with an amplitude of +0.84 volts is obtained.

Re: Mitsubishi Eclipse Cross 2020 AirCon HVAC

Hi. . If the filter-dryer is blocked in the air conditioner system, then both high and low pressure lines become gas suction lines. In this case, when the compressor is triggered, instead of increasing the pressure, a decrease will occur. All this is true, provided the nominal amount of gas in the s...

Re: Mercedes M120 Ignition Coil Testing

Hi. . You need to connect one channel to a common power supply wire to measure current. There are also two separate channels for the control wires. If there is only one coil per cylinder, it is enough to connect two channels. The first - is measuring the current on the coil power wire. The second - ...

Re: Fiat Doblo Cargo 1.3 Multijet idle quality and more

Нi. . Post-injection is not used in this mode. Two pre-injection and main injection are used. The timing of the main injection usually coincides with the TDC. If the injection occurs after TDC, then there is a displacement of the reference point. The ECU calculates the TDC based precisely on the sig...

Re: audi a4 2.0tdi 170km BRD synchronisation cam crank

Hi.
.
It would go faster if you showed the signal that was take-off from the engine.
There are a lot of modifications in the line of the EA188 series,
but a limited number of synchronization signals.

Re: 2012 VW Tiguan 1.6 Tdi CAYC Engine

Hi.
.
The first relay J906 is used for both variants of the starting system.
The second relay J907 is used only if there is a START-STOP system.
The relay contains a terminal 50R (diagnosis terminal 50) that is used -
in the operation of DC/DC INVERTOR J532 and ECM J623 in the START-STOP mode.
