caravan wont start after accident

[mcmicken]

On the plug or is this inside the fuse/relay box?

[serge_saati]

On the plugs bundle. I never seen a PCM or ICM in a fuse box.
But if it has only 2 plugs, it's neither the PCM nor ICM.

My caravan has a PCM. I have it pulled out & sitting in front of me.

[serge_saati]

Of course you have one.
But you said somewhere "It has 2 plugs on it". It's why I thought that it was something else broken. Like something with just 2 contacts.

[mcmicken]

Sorry. I meant that it has 2 rectangular ports where 2 plugs from the wiring harness plug into. So what should I do now?

[serge_saati]

Check voltage pulse on 3 inputs of coil when you crank. In the coil connector.
Normally, the PCM should send spark pulse w/o being re-programed.

[mcmicken]

What do I use to check voltage pulse?

[serge_saati]

A voltmeter.

[mcmicken]

Can I check the crankshaft position sensor the same way?

[serge_saati]

yes, but in mV AC for this one.
the other is in VDC.

Do you know where I can download a wiring diagram online?

[serge_saati]

There's no free online wiring diagram. But you can try google the schematic you want and if you're lucky, you'll find it.

But you don't need a wiring diagram for testing coil and CKP sensor or diagnose an ignition system, it's to simple. It's the same ignition diagram for all V6 since 1990. I can give you the ignition diagram of my car if you want.
