When I drive, the exclamations starts flashing constant, and the unit Veirs to the right, like the right motor is locking up. Any ideas? I have a caterpillar 226D
Sounds like a speed sensor or sensor wiring issue
Please post up a photo of the instrument panel located in the upper RH corner of the cab. Hopefully it looks like the photo below.
The third Symbol over the explanation is what isflashing. Where would the speed sensor be located at?
The serial number is in the first pic
OK, so you only have the basic level instrument panel which does not allow you to look at Diagnostic Codes and Events within the electronic control system. To progess with diagnosing the fault you really need those Codes. The best thing I can suggest is to find a local independent mechanic who has Cat ET and have him hook up to the machine and download a Product Status Report for you. That will show what is Active.
Thank you sir
