What this code means
Mismatch between the H&S input and the tiller input.
Applies to: ZAPI ACE0 / COMBIAC0 controller.
Possible causes / checks (from the source)
Check the harness related to CAN#1 and CAN#29 with a voltmeter. If the state of these inputs is right, then it could be a problem inside the controller, which has to be changed.
