What word goes before or after; soft, less, weak, light, check, blind

NO YEAR TOLD wow. 1995 to 2008 and no country told
2.9L petol engine 2.9 L V6 (aka 3L)
weak car battery? not 13.3 to 15vdc running means
bad alternator it its own fuse blown!
battery cable lugs all 4 ends not loose or rusty.
fuses check all fuses first.
if battery goes weak driving and a bad ALTerator.(ALT)
the voltage falls and computers on board fail or go wacky(chaos)
at 10vdc this can and does happen and the PCM and BCM both.

I call low voltage at the battery or bad fuses.
did you know that huge battery can be also intermittent"
good /bad/weak or wildly intermittent it sure can.!!!!!
so can too, the alternator.
a shop checks all that and more!@ load tests too.

they use the scan tool too, and it may tell you what is wrong.
i guess com2000 is the Peugeot BCM body computer
and it needs 2 things to work clean 12vdc power (fuses and ALT)
it need to communicate to other things, like PCM.
or fails. scan it next. look for comm errors
and more.

The check engine light will come on when the management computer detects a fault that can affect exhaust emissions. When that happens the computer switches to a get you home programme and records a fault code.

A code read is required to discover the fault which should then be verified by independent tests before wasting money chasing down blind alleys.

you have put this in a merc C class classification but you state its a van ,so iam assuming its a commercial vehicle but this doesnt make a lot of difference ,well firstly iam colour blind but a orange light is the generator as the oil light is red ,or it could be depending on the symbol a low brake fluid or even a low washer bottle liquid ,check all the levels first and see if goes out .

This can be poor grounding of the engine and alternator and battery as there is a potential drop. It can also be due to a mismatch with high load when the charging voltage is not balanced.
So since the alternator was replaced the rectifier/regulator also can have a small leak which is producing the soft light which goes off when the headlight is swithced off. A test may not show this because the charge would be seen but the fault is a tiny ac leak into the system due to the weak regulator. It might fail in the long run or casue static in radio.

Replace your master cylinder. It is leaking out of the back of the master cylinder and into the booster. If you unbolt the master and carefully look into the booster, chances are you will see brake fluid. Replace it, bleed the entire system, and enjoy your truck again.

If the alternator is bad, and it is cause battery light is on, the elec. system does not have enough power (voltage) for the system to work right,being that it's only working off the battery voltage till battery goes weak. Have an alternator check done or check voltage at battery with engine running, should have no less then 13.5 volt's.

iam colour blind so i cant help a lot because what i call red could be brown but here goes ,yellow indicator red stop light brown side light and green indicator blue fog light

I'm getting real suspicious of EGR valve fault. For now, pull vacuum line off valve, and see if there is vacuum at idle, plus see if engine straightens out, when line off, idle wise.

Did you try swapping plugs & wire with another good cylinder. Maybe bad plug or wire, even though check says wire good.

the contacts in your ignition module are either weak or shorting. the module is located in the steering coloumn. also the connection to the module could be the fault as well. check the connections first then replace the module. you can buy it at Napa or Oreillys for alot less than at a dealer and installation is not that difficult.. please rate.......thanks
