Digiprog III problem on a Toyota mr2 mk3 “chip not found”

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?

Answer:

Two things:-

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.

Question 2:

Tried to connect it the two ways it can be connected.. still nothing, this is btw the cable I got told to use.

Answer:
Short the cristol and try it.

Result:

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!
