Clark C35G Diagnostic code 69

Hello everyone, I am new to this forum and I am looking for advice or assistance with a Clark C35G forklift. I am currently employed by the central Texas veterans administration as a maintenance worker. We currently have a C35G that keeps sending off a code 69 and the display reads check engine/ engine error. I know if you press the accelerator 3 times it displays a code 12 and then any active code(s) (69) and then if you press the accelerator 10 times it clears the code. I looked online and can not find out what is a code 69 for this make or model. The unit seems to run fine with no codes for a prolong period of time at idle, but when you drive it after 10-15 minutes the code comes on and it goes into a limp home mode where the max speed is about 5mph. We are also wondering is there a diagnostic connector on the unit so a tech could possibly connect to the on board computer? Any advice or troubleshooting tips or procedures would be greatly appreciated thx.

Equipment Depot is the Clark dealer in Texas. Some things you are best off to call the OEM dealer.

Fault code 69 indicates a pedal position signal difference from what is expected. Check all plugs and wiring on throttle pedal assembly.(Assuming you have a unit with Woodward fuel system)
There is a diagnostic port to connect a laptop but you require Woodward software and security fob to access.

Fact of the week
In 1898, author Morgan Robertson wrote a novel called 'Futility', which described an "unsinkable" ship named the Titan that sank after hitting an iceberg. Fourteen years later, the Titanic sank in a strikingly similar fashion.
