This fault code can appear with a fresh Gen 3 install or when a CCIM has been replaced.
The EQSS CCIM uses PCB mounted DIP switch banks for forward/reverse telehandler drive logic settings. These settings are configured at the factory and can be telehandler make/model specific. If these DIP switches have been configured incorrectly for a particular telehandler, it is possible for the Gen 3 system to report a T14 fault - signifying that both telehandler forward and reverse gears have simultaneously been selected (when they have not). This condition can also create cutouts that will inhibit machine operation.
Troubleshooting:
If the Gen 3 kit is brand new and is a fresh install on your telehandler/itc or you have received a repaired/replaced CCIM that is creating a T14 fault code:
1. Unscrew the four screws on the CCIM and open the lid.
2. Take a few very clear photos of the two DIP switch banks on the left hand side of the Circuit Board (near the two blade fuses).
3. Open a web browser on your computer or mobile phone and navigate to the support page on the EQSS website.
4. Fill in your details and attach the photos of the two switch banks then submit your support request; please make sure that you have provided accurate details of the make/model/serial number of your machine.
5. We will reply to you with correct DIP switch settings for your make/model of machine
Furthermore, some models of Manitou telehandlers also use a CAN IO module that sits between the Manitou CAN communication system and the EQSS Gen 3 system. That CAN module requires proper ground and 12 Volt supply rails. If the fuse that supplies power to the CAN IO module blows, then that condition can also force a T14 fault on the EQSS Gen 3 display.
Please, don't be tempted to just randomly change DIP switch settings in the hope that the system will somehow come good - these are control lines and need to be set purposely.
