1993 Nas Defender 110

[ROVERMAN]

A couple of days ago I ran into a website dedicated to repairs and tech information on the NAS 110. Does anyone have the link? Thanks

Why bother? They're the same as a D90 but longer. The same as an RRC with less sheetmetal.

everything except the AC/heater.

everything except the AC/heater.

And there isn't a big difference between a D90 and a D110 there either

How do you reset the codes on the 110 computer?

How do you reset the codes on the 110 computer?

Disconnect serial mating plug, wait ten seconds, reconnect. Turn key off, wait for relay to drop out, turn key on. If no codes remain, there will be nothing indicated on the display. If more codes remain, this procedure must be repeated until all codes are read and cleared.

Or, plug in the Rovacom and push the button

Wtf?

Wtf?

Only hacks pull the fuse!

Sorry about the question, but want to be sure....... Is the serial mating plug the one with all the wires going into the computer? or something else............

 

[ptschram]

Adjacent to the ECU, there will be a five pin white connector with a wire going from both portions of the connector. This is the serial mating plug that is used for diagnostics if you have the correct reader.

Got it!!! Thanks

you could just disconnect the battery or disconnect the plug from the ECU for all of 2 seconds. turn car on. get code 2. turn car off until main relay times out. turn car on. profit.

The problem with this method is that it also clears any unread codes and replaces them with code 2, power interrupted to ECU. If one follows the correct procedure, it clears codes sequentially and allows all of them to be read and recorded.

If you disconnect the battery and reconnect it quick enough you don't have to enter the radio code.
