Default Slow Club Car DS

Hi guys,
My name is Danny and I'm from Germany. Sorry for my bad English.
I bought a Club Car DS 48Volt (AQ0629) two days ago. There are 4 12 Volt Trojan batteries installed, which are 1 year old. Now I have the following problem.
On a straight track the Club Car only drives between 5-6 MPH. As soon as it gets a bit uphill, it gets a lot slower.
I have already measured the batteries under load and everything seems to be in order there.
I also did the speed sensor test and the beep was heard and it slows down automatically.
I also checked the battery cables and they seem to be ok too.

Does anyone have an idea what else it could be?

Thanks in advance!

That is an '06 IQ (Sepex) cart. Below are the speed codes that can be programmed into the Curtis controller.

Speed Codes for IQ:
Speed Setting 1 = 8 MPH
Speed Setting 2 = 13.2 MPH
Speed Setting 3 = 14.8 MPH
Speed Setting 4 = 19.6 MPH (Private Code - Purchase required)

That speed is below SC-1 so you may be in limp mode that cuts you to half speed. A failed speed sensor could cause it, a welded solenoid could cause it, just real hard to tell from here.

What was the pack voltage when you checked it - should be 50.93 volts 12 hours AFTER the charge completed.

If you want to make sure the MCOR is working correctly AND your throttle is reaching 100%, do the following:
With the batteries connected, Tow/Run switch in Run; place the black (–) probe on packs main Negative post and the red (+) probe on the yellow wire at the 3-pin connector near the MCOR or at the Controller. (The reading should be approximately ~0.32 - .5vdc with the pedal up). Slowly press the Go Pedal and the readings should increase gradually until it reaches ~4.65 - 5vdc when the pedal is fully depressed. (Anything less than 4.60vdc and you are not reaching full throttle).
