Topic: Digiprog III problem on a Toyota mr2 mk3 “chip not found”
Question 1: When I try to connect my c46 plug which the Digiprog 3 says I’m supposed to use to adjust the milage (the old one broke and I got a new one that has a lot higher mileage than the original odometer), I get the message “chip not found” error…does anybody know why?
1. make sure you are putting your c46 cable on the right chip (93C46).
2. Make sure you’re putting the cable on the right way round, the chip normally has a marking where PIN 1 is located, this should be connected to the cable with PIN 1 touching the PIN with the red wire on your cable.
Tried to connect it the two ways it can be connected.. still nothing, this is btw the cable I got told to use.
Short the cristol and try it.
It works now, i started looking more carefully on the adapter itself.. which had plastic residue on the clip so it wouldn`t grip the chip enough to make full contact!
