Unknown Dashboard Light

This is an interesting one! I have a dash board light that is a car with a lock in front of it. (I attached a picture of it). I went to start my Axis and this light was flashing red when I turned the ignition on. The starter did not engage – nothing happened. This same thing happened a while back last year but when I turned the key on and off a few times the light stopped flashing and the vehicle started. Never happened again until this week. The truck would not start, batteries were all charged. All coach utilities were fine. I tried everything I could think of – with shore power, without shore power, with generator running, and without. Nothing. I then removed and thoroughly cleaned all the battery connectors on the chassis battery. Still nothing. Thor said there is no such light on the dash (sorry!) and he said it must be a Ford issue (chassis) and not a coach issue. Ford’s web site lists a bunch of dash lights – but not this one! I desperately disconnected both wires on the Battery Isolation Monitor and cleaned them thoroughly. Turned the ignition and the light was not flashing and the unit started as normal. This could indicate a BIM going bad and I plan to replace it. Anyone have any thoughts? Anyone have this light on their dash?

If the BIM is bad it has a manufacturer 5 year warranty

A tech will have you do a few tests on it. If bad they'll send you a new one.

Give them a call

Car Immobilizer. Anti-theft light.

Nothing to do with the BIM.

30 second Google search will tell you more than you want to know. Read your manual on anti-theft.

That was my thought as well": an anti-theft system that is going wonky.

It's a Ford item.

(I had a Chevy that once played the same games with me.)

Red flashing it is working just fine and anti theft is on. That replaced the flashing red light that some cars have on the dash. I

But if it was flashing, and the vehicle couldn't be started: something is amiss...

Not necessarily. Red Flashing the system is armed and working as intended.

Not starting is a different problem and could be related to the key itself. There could possibly be a dead or weak battery in the key fob. The key may not have been inserted into the ignition switch all. the way. Could also be a key that has not been properly mated to the system after it was activated.

The system is working but there is no where enough info in the OP's original post to determine if there is a real problem other than not being familiar with the vehicle's systems and operation.

You certainly are correct in that we could use a bit more info...

But I would discount the possibility of a weak battery in the key: until proven otherwise... they normally last for years.

There are also cases where the system went active for one reason or another such as someone try's using the wrong key etc... and the owner had to disconnect the negative battery cable to clear the alarm and start the vehicle.

I have had 2 instances where keys were delivered with a new vehicle and the fob or active key batteries died within a month. Keep in mind, that chassis may have been a year old when Thor started assembling the motorhome and I'm sure they don't change the key fob or key batteries before a coach is delivered (if the coach uses those type fobs or keys). Another type of key, I believe, could have lost its coding by being too close to a strong magnetic field.

Again, not enough info. I don't know what Ford has done to or with the E series chassis in the last 7 years or so.
