MASTERCELL Input Troubleshooting and Diagnostics

Our Infinitybox system has powerful diagnostic and troubleshooting features built into it.  The MASTERCELL in your 20-Circuit Kit includes our inSIGHT LCD Screen.  This screen is your window into the Infinitybox system and it gives you access to the MASTERCELL Input Troubleshooting and Diagnostics.  By pressing a few buttons on the MASTERCELL, you can put it into its Messaging Mode.  This blog post and the attached video will show you how the Messaging Mode can help you wire your car faster and identify problems easily.

All of your switches connect to the MASTERCELL.  These include your ignition and starter switches, your turn signal switches, your brake pedal switch, the switches for your lighting, your fuel pump and cooling fan triggers and any other switches that you have for your accessories.  The MASTERCELL continuously watches the state of your switches.  If it sees one of these inputs turn on or off, it sends commands to the POWERCELLs or inMOTION cells in your system and commands them to turn an output on or off.

The MASTERCELL can be put into its Messaging Mode.  This mode opens up the MASTERCELL Input Troubleshooting and Diagnostics feature in your Infinitybox 20-Circuit Kit.  To put the MASTERCELL into Messaging Mode, you simply press and hold the “SCROLL UP” and “SELECT” buttons under the clear cover.  These are the two buttons on the right, under the inSIGHT LCD screen.  Press these buttons together, hold them for one second then let them go.  You will get a message on the screen that says “inSIGHT WILL DISPLAY ALL INPUT CHANGES FROM ANY SOURCE”.  You will also note that the back light of the inSIGHT LCD will turn on and stay on.

When you turn any MASTERCELL on or off, the inSIGHT screen will confirm that.  It will tell you which input the MASTERCELL say turn on or off.  It will also tell you which cell it is supposed to be controlling and which output.

The following video goes through this in detail.  You can see which buttons to press to put the MASTERCELL into Messaging Mode.  You will also see what the messages on the MASTERCELL screen look like when you turn inputs on and off.  Check out the video here.

Messaging Mode is a very powerful tool.  You can use it as you go through the process of wiring your car or truck with our Infinitybox system.  You can wire each switch, step by step, then use Messaging Mode to confirm that you have the correct input wired to the switch by following the details of your Configuration Sheet.  You can also use this to confirm that you switch is working correctly and that you have good grounds for each of your switches.

If you have problems on the road, you can easily put the MASTERCELL into its Messaging Mode and check for any issues with your switches or the wiring from the MASTERCELL.  No tools are needed.

MASTERCELL Polling Video

We pack a ton of powerful diagnostic tools into our Infinitybox 20-Circuit Kit.  With no tools, you can use the inSIGHT screen on the MASTERCELL to learn about everything that is going on in your car’s electrical system.  There is no other wiring harness on the market that can get you that power.

We just published another video going through the specifics of the built-in troubleshooting and diagnostic tools in your Infinitybox system.  This new video covers Polling the system from the MASTERCELL.  When the MASTERCELL power up, it takes an inventory of all of the cells on the CAN network.  This includes your POWERCELLs, inMOTION Cells, inVIRONMENT cells and inTOUCH NET.  From the MASTERCELL screen, you can easily check to make sure that all of the cells are properly communicating on the CAN network.

You can also dig deeper into each cell by polling it from the MASTERCELL screen.  By polling the POWERCELLs, you can get a measurement of the battery voltage measured locally at the POWERCELL.  You can also get a reading of the temperature of the POWERCELL.  You also get a measurement of the Charge Pump voltage on the POWERCELL.  This is a safety system that we monitor to make sure that the POWERCELL is operating correctly.  Lastly, you can get a picture of which outputs are on and off on the POWERCELL.

If you poll the MASTERCELL, you can get a real-time status of all of the switches that are connected.  This is really helpful for troubleshooting and checking your switches as you wire them to the Infinitybox system.

You can watch the new video that goes through polling the system from the MASTERCELL in detail.

Error Log

There are lots of things that set our Infinitybox wiring system apart from traditional harnesses.  Our troubleshooting and diagnostics is probably one of the most significant features that we offer.  The system will tell you where there are problems in the wiring harness, with no tools required.

One of the more significant features that is built into every one of our systems is our Error Log.  This is an advanced troubleshooting tool that can help to identify problems with a system installed in any vehicle.  The system actively monitors key parameters in the wiring harness.  If these go out of their expected range, the MASTERCELL stores these errors and has the capability to display them back for problem solving.

Let’s start with a deeper dive into how the system works.  When you turn on a switch, the MASTERCELL sees the input get grounded.  It sends a signal to the POWERCELL to turn on an output.  Before the POWERCELL can turn on that output, it needs to check to make sure that everything is safe to do so.  There are three critical parameters that the POWERCELLs check before they can turn on an output: the primary battery voltage, the charge pump voltage and the POWERCELL temperature.  The POWERCELL is continuously monitoring these values and making decision on what to do with them.

The primary battery voltage is an easy one.  The voltage that the POWERCELL is fed from the battery has to be in a specific range.  A charged battery should be at about 12.8 volts.  When the engine is running and the alternator is charging, that voltage should be between 13.8 to 14.2 volts.  The Infinitybox system has internal high and low limits that it watches for the primary battery voltage.  The system can operate down to 6.5 volts and up to 19.0 volts.  If the measured voltage goes outside of these limits, the POWERCELL will shut the outputs off for safety.  In general, your system should be operating between 12.2 and 14.2 volts.  If you’re outside of that, you have a battery or charging issue.

The next one is charge pump voltage.  This is an internal measurement that we take to assess the health of the POWERCELL.  A charge pump is exactly what it sounds like.  We have circuitry on the board that pumps up a charge and stores it.  This stored charge is used to turn the MOSFETs on.  We don’t use relays on the POWERCELL, we use solid-state MOSFETs.  These can do a lot more than a relay but they need to be turned on a specific way.  That’s what the charge pump does.  We monitor the charge pump voltage and display it as part of the POWERCELL statistics.  Depending on the software version, some systems will display CP Volts.  Other systems may display CP Delta.  If  your system shows CP volts, this number should be above 22-volts.  If your system shows CP Delta, it should be above 12.0.  Again, this in an internal measurement that we use to assess the health of the POWERCELL.

The last measurement that we take is board temperature.  Each board has a small temperature sensor mounted on it.  This lets the processor monitor the temperature on the printed circuit board.  This temperature is a combination of the heat generated on the board and the heat from the environment that the POWERCELL is mounted in.  All of the components on the POWERCELL boards are rated to 125 degrees Celsius (257 degrees Fahrenheit).  If the board temperature measured by the processor approaches this 125 C limit, it shuts the outputs down for safety.

So lets look at the error log.  If a POWERCELL records an error, it sends it to the MASTERCELL which stores it in a list.  The MASTERCELL stores 8 errors.  New errors that are recorded push the oldest errors out of this list.  The MASTERCELL reports the Uptime when the error was recorded, the cell that reported it and the outputs associated with it.  The uptime is a clock that starts when the system is powered up.  You can see this when it is running normally.  This is not a real-time clock because it does not continue to run when the system is shut down.

To get to the error log, you first remove the clear cover from the MASTERCELL.  Then you press and release the HOME and SCROLL DOWN buttons under the screen.  Hold them together for one second then let them go.  The MASTERCELL will display any errors that it has stored.  If you want to stop the error log process at any time, simply press and hold the HOME button for 5 seconds.

Our technical support team can learn a lot about your electrical system by looking at the events recorded in the error log.  It is usually easiest for you just to record a video of the error log running with your smart phone and send that to our team.  We can analyze it for you.

By looking at the events in the error log, we can identify problems with your grounds, your battery, your charging system and how you have the system installed in your car.  Check out this video to learn more.
