The Cadillac service manual says for the B terminal is a tan/black wire, for the E terminal is a white wire , for the R terminal is a purple/white colors may have faded! Any more trouble I got the book!

    Terminal B connects to C on the four way connector and terminal E connects to A, Terminal R connects to B The illustration only shows the color of the wires going to the four way connector and not from the connector to the module .With the terminal facing you un pluged and the clip on the left side A will be at the bottom then b,c d to the top.

1990 Cadillac Eldorado Biarritz reading shows the code e52. How do I fix?


Question
90 Cadillac sedan deville 4.5L My car won't turn over all the power is gettin to the vehicles dash tried the trouble shooting it said it was the ECM memory reset so I changed the ECM computer and it is still doin the same thing some people say it might b the saftey neutral switch but i want to no from someone with experience opinion. I have changed the ignition module and the ECM computer recently and it still does nothing

Answer
Hi Chris, The code E52 just means that the ECM lost power or ground or that someone forgot to clear the code after hooking the battery back up. It could mean a bad computor but not very often. 2 things that come to mind is a bad ignition key or lock cylinder or a faulty neutral safety switch. Try the other ignition key first. Then with your foot on the brake pedal hold the key in the start position and move the shifter slowly from P to D. If it tries to start then the NS Switch is bad or out of adjustment. If it still won't start then you will need to troubleshoot the ignition key/PASS KEY system for an open wire in the steering column. Hope that helps. Bill
