CID 0352 Position Sensor (Lift Lever

FMI 13 Lever not centered on power-up. Loss of lift function until key is turned OFF.

CID 0358 Solenoid Valve (Pilot Pressure Supply)
FMI 05 Current below normal or open circuit. Implement system will not operate.

Can you tell if either one of those codes is active. If its active there will be a service code symbol flashing next to it when youre viewing the codes on the monitor.
Neither one of these codes will cause the loss of just the tilt function. You may have more codes or there is a mechanical / hyd problem causing it.

If the bucket won't lift it is the first code. Make sure the control lever is centered before you start it and it should work again. I find it can take a couple starts to get it functioning again.

If nothing works its the second code. you will probably find a failed pilot shutoff solenoid but it could also be wiring in the articulation area.

hi if you have SIS follow the procedure "using caterpillar monitoring system to determine diagnostic codes"
post back the fault codes. from experience with these machines most of the time with an isolated failure of hydraulic system it is the solenoid on the control valve .where they are located makes them prone to extreme conditions mainly dirt build up which contains moisture and heat and allows corrosion to cause problems
WHAT IS YOUR SERIAL NUMBER?
