Where do i start?

[SShafranko]

On my Edge monitor, when i turn on my headlights the egt gauge goes up 100 degrees. If i turn them off it goes back down 100 degrees instantly. If i turn up the volume on my radio the egts gradualy rise as i turn the dial and back down the same way. It seems like a voltage issue. But is it the Edge or my truck? How are they communicating? Please help.

check to make sure the power wire on the edge that goes to the to the fuse box is plugged into the right fuse. could be a bad box. the g56's are different than the autos "edge juices"make sure you have the right part # they will work but theirs some differences.

Has this been happening all the time, or is it a recent event?
What circuit is the Edge getting power from?
Where is the ground point?
Are your thermocouple wires routed away from other signal sources and are they a twisted pair?
Looks like you have a bit more than a stock stereo and may be inducing voltage into the EGT circuit.

It is getting power from a fuse in the box. Not sure which one but i will check tomorrow. It is the same fuse for past three years.



The ground is bolted to the chasis. Scraped paint off and tightened well.



Thermocouple i have to make sure tomorrow but i believe that it is away from everything and zip tied. I also changed it to be sure it is functioning properly and same result.



This started a couple of months ago. All my stereo equipment and TVs were installe two years ago.

I have had the same box for three years now with no issues whatsoever. I believe i have the right box. Thnx.

Is there any way to check it? I should probably mention that a couple of weeks ago my blinkers were also going crazy and i unplugged the harness in the column and plugged it back in and now they work fine. My trailer lights are also acting up and i will check the trailer end tomorrow. Thnx for your help

Well, if all of your connections are good, the wiring shielded, and equipment has been in place and unaltered for some time... hmm, a tough one. What do the readings do when the truck is turned on but not running and you do the lights and/or the radio - each independently and then together? You probably don't have an extra Edge box laying around for troubleshooting purposes...

Suspect list:

1. Edge box
2. PCI

The 06/07 have a touchy TOTALLY INTEGRATED POWER MODULE it may need to be reset and updated.

COMMUNICATION

DESCRIPTION

The primary on-board communication network between microprocessor-based electronic control modules in this

vehicle is the Controller Area Network (CAN) data bus system. However, on SRT10 vehicles the Powertrain Control

Module (PCM) uses the DaimlerChrysler Programmable Communication Interface (PCI) data bus system in combination

with the CAN bus to form a hybrid bus system. A data bus network minimizes redundant wiring connections;

and, at the same time, reduces wire harness complexity, sensor current loads and controller hardware by allowing

each sensing device to be connected to only one module (also referred to as a node). Each node reads, then

broadcasts its sensor data over the bus for use by all other nodes requiring that data. Each node ignores the messages

on the bus that it cannot use.

The CAN bus is a two-wire multiplex system, while the PCI bus is a single-wire multiplex system. Multiplexing is any

system that enables the transmission of multiple messages over a single channel or circuit. The CAN bus is used

for communication between all vehicle nodes, except on the SRT10 where the PCM uses the PCI bus. In addition,

certain vehicles may also be equipped with a Serial Controller Interface (SCI) or a K-Line serial link bus to provide

direct diagnostic access between a diagnostic scan tool connected to the industry-standard 16-way Data Link Connector

(DLC) located below the driver side instrument panel and certain powertrain nodes.

There are actually three separate CAN bus systems used in the vehicle. They are designated: the CAN-B, the

CAN-C and the Diagnostic CAN-C. The CAN-B and CAN-C systems provide on-board communication between all

nodes in the vehicle. The CAN-C is the faster of the two systems providing near real-time communication (500

Kbps), but is less fault tolerant than the CAN-B system. The CAN-C is used exclusively for communications

between critical powertrain and chassis nodes. The slower (83. 3 Kbps), but more fault tolerant CAN-B system is

used for communications between body and interior nodes. The CAN-B fault tolerance comes from its ability to

revert to a single wire communication mode if there is a problem in the bus wiring.

The added speed of the CAN data bus is many times faster than previous data bus systems. This added speed

facilitates the addition of more electronic control modules or nodes and the incorporation of many new electrical and

electronic features in the vehicle. The Diagnostic CAN-C bus is also capable of 500 Kbps communication, and is

sometimes informally referred to as the CAN-D system to differentiate it from the other high speed CAN-C bus. The

Diagnostic CAN-C is used exclusively for the transmission of diagnostic information between the Totally Integrated

Power Module/Central GateWay (TIPM or TIPMCGW) and a diagnostic scan tool connected to the DLC.

All vehicles have a central CAN gateway or hub module integral to the TIPM that is connected to all three CAN

buses. The TIPM is located in the engine compartment near the battery. This gateway physically and electrically

isolates the CAN buses from each other and coordinates the bi-directional transfer of messages between them. On

SRT10 vehicles a separate, dedicated gateway module secured to the back of the battery tray on the right side of

the engine compartment coordinates the bi-directional transfer of messages between the PCI bus line from the PCM

and the CAN bus connected to all of the other nodes in the vehicle.

With the truck off and the ignition on the egt gauge reads 15 degrees. If i turn my parking lights on it jumps to 150 and if i turn the headlights on it jumps to 240. If it is a problem with the PCI, do i have to go to the dealer?

Next time your blinkers act up and they will change the position of the tilt wheel I'll bet they start working if not its the BUSS I've had problems with both. Good Luck Randy

Does the edge monitor use the data-link connector for any of its functions?

Yes it plugs into it and stays plugged in. It reads mph, slip, water temp, etc. from the truck's computer.

I'll call you Monday mid day. Thnx Todd

 

[SShafranko]

Todd,



TY you for taking the time out from your busy day to speak to me. i WRAPPED ALL WIRES AS WE SPOKE ABOUT AND RE-ROUTED EVERYTHING ON ITS OWN and it worked. All that work and i just traded my Edge for a Smarty.



Thanks aagain,



Sasha
