Exclamation warning light

Just picked up a used D5G the other day - today while I was running it up for a while, the "exclamation mark warning light came on for around 10 sec then went back off.

What's the purpose of this warning light?

Thanks in advance.

Taking a guess, but it sounds like there might be a service code popping up, is there a buzzer/any other lights appearing with it?

You should have a "circled check mark" button next to the hourmeter (I think, I'm a little fuzzy on the d5g cab layout) where you can cycle through hours, rpms and any codes that are appearing. When you find the code, write it down and either look it up or call Cat and they can look it up. Could be as simple as a bad sensor to an actual problem starting to appear.

Just my two cents... I could be way off:pointhead:drinkup

Was it an exclamation point or could it have been a thermometer? Was it amber? My Cat skid steer has an amber thermometer (looks like an exclamation point) that indicates the hydraulic oil is not at operating temperature. In cold weather it will come on at start up, and then again when I initially move the machine until the oil warms to within spec. Use the machine at low rpm and operating power until the oil warms so the pump doesn't cavitate.

Mine is a 2002 model so I'm not sure it has all the computer diagnostics. I don't think it's the warning light for the hyd pressure.

I'll have to look at it again but it looked like an exclamation mark.

I did find flyer on my machine and I copied the list of warning lights below - looks to me it's the Electronics fault light which blinked. Not sure what the problem could be.

Indicator lights:

- Low engine oil pressure
- Parking brake
- Hydraulics filter bypass
- Low alternator charging
- Electronic control fault

I know on some of the machines I have run, that light will come on and stay on when you turn the key from off to on, then start the machine. Once the oil pressure comes up, it will ussually go off.

Also, check your oil level. If you have low oil, it could cause a momentary low oil pressure if going from high rpm to idle.

Check all your fluids, belts, hoses, and go from there.

Is it exclamation inside a triangle? If so that's a code and you can retrieve it like it was mentioned above. The one I had would show the code when you cycled to a blank screen, just wait a second and it will give it up, first code designates type of problem and second is the exact part not working.....I think. 2002 should have the electronics.

My machine is a 2002 model so there is no display screen at all - what I have is idiot lights just like a car. The light just flashed on for a few seconds then went off. The flyer shows that light as the Electronic control fault warning so I guess it could be a number of things. I'll check the levels on everything like you gius mentioned.

Thanks

If all fluid levels are good, could possibly be a sensor or sending unit starting to go bad. Start with oil pressure and temperature first, I've had to replace both of those before. Maybe a plugged filter?:beatsme

The service is not due for another 100 hrs or so. The gauge show good pressure so it might just be a sensor.

More than likely it is for a filter bypass situation. In cold weather the hydraulic or transmission filter will not be able to allow all the oil to go through it, so a bypass valve on top of the filter opens and lets the excess oil bypass the filter. Once the oil warms up some the filter can now handle it and the bypass closes making the light go off. It's probably nothing to worry about unless the light comes on when the machine is at operating temperature.

I haven't seen a D5G that didn't have an electronic display on the dash panel. I am wondering if this machine is a grey market unit.

Warning light....

Seen alot of alternators go out on these with early hours so check your voltage while it's running with all lights,radio etc. turned on. If the oil pressure sensor goes out the light would stay on so probably not that. It won't cost much to have a tech. hook up and check for you, it takes about 5 mins.

Here's an image of my dash - there is just a cluster of idiot lights in the center of the dash assembly. Here is what the the lights cover:

Monitoring Package. The new
monitoring package allows the operator
to be aware of system conditions without
having to constantly view gauges.
Fuellevel, hydraulic oil temperature,
oilpressure, coolant temperature,
andmaximum speed setting gauges
areallincluded in the instrument panel.
Indicator lamps warn operator of:
• Low oil pressure
• Power train oil filter bypass
• Low alternator voltage
• Parking brake engaged
• Electronic control fault

You could do like they do out at a coal mines: Put electrical tape over the warning lights, and disconnect the buzzer so it won't hurt your ears.:pointhead

The D5G has one Electronic Control Module that controls and monitors the Hydrostatic system. The exclamation point lights up to indicate that the ECM has detected a fault in the Hydrostatic Electronic Control System. If it came on and went back out in 10 seconds, and if you did not hear an audible alarm, it was likely a momentary signal loss, just a "glitch". Next time you are at your Cat dealer, or they are out working on the machine, they can hook up Cat Electronic Techinician and tell you what fault was logged. If it continues to happen, or if it comes on and stays on, or if it comes on along with an audible alarm, you should get it checked. If it does not happen again, it was probably just a glitch and won't cause any problems.
There is a procedure to check fault codes without Electronic Technician but it involves jumper wires, counting the number of times the light flashes , etc. and is not really worth the effort.
