Notes

This protocol will have more things added in future. Non-Haltech products on the same CAN bus may cause CAN bus ID conflicts when that happens.
This protocol can change at Haltech's discretion.
The rates specified above are not guaranteed.

Traction Control States

Traction Control State channel	Raw	Enabled Bit	Active Bit	Light Bit	Notes
CAN ID		0x3E4	0x3E4	0x3E4
Byte:bit		3:7	3:6	7:0
Function Disabled	-1	✗	✗	✗	Function disabled in the software
Idle	0	✓	✗	✗	Enabled, slip is currently less than target. Or Driven Wheel Speed is below Min setting.
Active	2	✓	✓	✓	Slip is greater than target slip. Action is being taken. - PID control style has an RPM limiter active - Cut Percentage style the cut percentage table is being obeyed.
Ramp Out	4	✓	✓	✓	After being Active, the PID controller ramps the RPM limiter up while in this state.
Disabled	5	✗	✗	✓	Disabled by the Traction Control Switch and/or Conditional Activation. Light bit is on to warn the driver that the traction control is inactive.

Generic Sensors
