289D Caution light NO 2 Speed

[OLDDODGETRUCKS]

Hello,

I just purchased a Cat 289D S/N CAT0289DETAW02307

Everything works great on the machine except the 2 speed function is INOP and it has a caution light on (Not flashing just solid). Is there a way i can determine which code is related to this caution light without Cat ET/Sis? If not can someone post or send me a wiring diagram for this machine so i can start troubleshooting the 2 Speed issue?

Thank You

Not sure you can pull codes without ET on that machine, unless you have the supplementary instrument panel in the upper RH corner of the cab.

I'll ship you the electrical schematic. Check your PMs.

Do you have an Operation & Maintenance Manual for it.?
If not it might pay you to get one. Cat Publication SEBU9084.
