update I am always open to different processes for testing so sure whenever or how ever is fine with me. Took it out for test and all areas of DIC are blank, NO CODES, NO MESSAGES, NO MPH LIMITS OR SHOCKS INOPERATIVE on the DIC. Thanks for the discussions and data support. Tom

I was initially looking to see if the relay was getting activated or if the coil was not getting triggered to pull in the contact. still a mystery but its working

Relay The meter is measuring the coil and it did change voltage state. But you are correct it may have altered the circuit just enough....That's why others looking at a challenge is just good business. I will go out and do the contacts today. Question.....with the meter off and if it was...

update happy it is working, unhappy no definitive solution was identified as of this point. no difference when I removed the volt meter....still communicating ok working on the grounds just to be sure, looking at possible wire issue in ESC connection both in the trunk and at the underneath...

tech 2 issue recap ok, went out this a.m., jacked car, re-installed ESC, hooked up volt meter to RTD Relay, Hooked up Tech 2, VIOLA....I do not know why but it is talking and communicating when before it did not. Is it the ESC, Could the Volt meter connection have affected the way the relay...

tech 2 issue recap Fresh morning, so just want to recap where I am with this challange. 1 I get the message "shocks inoperative, max speed 80 mph" 2 went thru the DIC IP and checked codes....none found! 3 hooked up recently obtained TECH 2 to identify issues and checked car for...

info update ok, i pulled the ESC module from the LR TRUNK panel, all pins loo good. Pulled the RTD relay out of the fuse panel by battery and ohm checked it at 86.6 ohms, contacts NO were NO. I may try to figure a way to recheck the contacts in the panel this weekend to see if they close. by...

shocks / no communication first thanks to all for the reply's. Being a Senior Citizen requires me to get all the assistance I can from this GREAT forum and its MEMBERS. 2nd I slept on it and this morning went out and just did a step by step walk thru the tech 2. IT WAS WORKING CORRECTLY ALL...

Shocks inoperative Hib, thanks for the reply, I have power now to the DLC BUT still get the no communication message, I have to finish checking the connections under the car tomorrow and put it back on the ground. is there a way to view the PIN 2 output/voltage or whatever it puts out with a...

Shocks inoperative oK, now have power to the DLC, tech 2 powers up but when I try to get communication it fails, tells me to check connection (on/off) how to check the bus or what to do next to overcome the communication problem with the Tech 2 out of effort for today. any suggestions for...

Shocks inoperative Anyone help on trouble shooting the DLC since I do not communicate with my 97 vet....94 vet does so I know its not the Tech 2. Pin 2, Pins 4 & 5, and pin 16 I understand are the main ones.....what values or readings should show up on probing them and what to use....ohm meter...

Shocks inoperative ok, car up on stands but decided to give the Tech 2 another try, no communication with 97. went to the 94 and connected the Tech 2 and had communication and access to screens. SO, anyone give me directions as to why/how to determine the NO Comm issue. I did not find a fuse...

Shocks inoperative Thanks for the reply's and the pulling of code information but already understood that process. I have pulled the codes on the IP and there are NONE. But the message for the shocks and reduced power shows up. The FSM talks about some soft codes that the way I interpret...

I have a Tech 2 and have gone thru the programs and screens and done the basic tests. I am trying to use it (suppose to be able to access/test shocks/actuators) to find out why my shocks are inoperative. Can anyone provide me instructions or a link on where this test is performed in the tech...

Hi, can someone direct me or give me the info on these numbers on a Dana 44 casing. #s D7 28 99 B dana G 50066 P81 607 41 10 then big letters f49. l ooks like pinion nut is 1 3/8 thanks, tom

JohnZ, thanks for the torque info...I was only 5 lbs low on each of the values you listed...thanks for the info...is there a web link to list all the major torque values for the mid year and late 60's cars. I know some other C4-C5 forums have compiled specs as stickys so do they exist for the...

86 flickering FIXED 86 flickering lights FIXED Well, the problem was the alternator as some of you responded. Even though I disconnected the terminals for the first check I assume the fact it was still turning with the engine that whatever failed internally caused enough of an induced field...

c4c5specialist Thanks for the reply. There are no other lites flickering except the interior and dash lighting. headlights, brakes, turn signal etc are all off. I can of course dim the dash with the dimmer switch but it does not change the flickering...only the light level. would the...
