I'm missing a ASCD control Unit on my 96 240 that im putting back together, What is all my options as far as the ones that will fit a 96 MANUAL KA?

I heard a keyless entry ASCD control unit wont work on a Non-keyless entry ASCD

also will a 97/98 KA ASCD Control Unit work on a 96 Manual KA??

Thanks in Advance guys.

Also if anybody has one for sale please pm me.

Hmmm... I would look at the FSMs and compare them.

Keyless entry has absolutely nothing to do with the ASCD. Two completely different systems.

TurK · 01-10-2008, 06:22 PM

Alright, so would any manual 96 KA ASCD control unit work? What about 97/98KA

Can anybody help out?

Thanks

Any 95-98 ASCD unit will work.

But before we go on, since you've brought up questions about the keyless entry, do you know what the ASCD is, and where it goes?

TurK · 01-12-2008, 06:20 PM

I know where it goes, I'm pretty sure it controls the fuel pump, cruise control..etc...

so a 95 OBD-I ASCD will work on a 96 OBD-II ?

Thanks TurK

ASCD stands for Automatic Speed Control Device.

it is nothing more then a vacuum pump and electronics to control that pump, that holds the throttle open to maintain a cruise speed. It is ONLY the cruise control.

Check the FSM that oughta help out.

So should my car still start w/ out an ASCD? Because is not and we think this is why.

projectRDM · 01-13-2008, 02:06 PM

There is no OBD-I and OBD-II ASCD unit, they're all the same. It controls nothing more than the cruise control actuator and operating system. Removed it's just a dead plug, nothing else is affected. Base 95-96 cars aren't even prewired for cruise.

The fuel pump is controlled through the ECU only. Black/pink control wire to the relay, black/yellow feed to the pump.
