Cruise Control Reset after Tune ECU access.

Triumph Rocket 3 Cruise Control Reset Sequence

If you have been accessing the ECU through TuneECU and performed any adjustments, it is possible that your Cruise Control will stop working. Good Triumph techs will know of the issue and the fix, but most in my part of the world at least, are hopeless and will start hours of diagnostics, suggest changing ECUs, TFT displays switch cubes and all this other thousands of dollars bull****. If a fault check with TuneECU shows no fault codes and your Cruise Control does not engage here is the sequence to reactivate.

1 - Switch ignition on to stage 2 fuel pump engaged but do not start.
2 - Depress Front Brake Lever and release
3 - Depress Rear Brake :ever and release
4 - Pull Clutch Lever and realease
5 - Roll Throttle forward, you will feel and little "notch" that it goes over and release
6 - Push the SET {lower} Switch on the Cruise Control Rocker Switch and release
7 - Push the Reset {upper} Switch on the Cruise Control Rocker Switch and release
8 - Start Engine
9 - Turn engine and ignition off
The system is now reset.

TuneECU will tell you to run the above switch check when you get DTC 1575 displayed. This DTC does NOT light the MIL. Once the switch check is done the DTC is reset.

From the Shop Manual:
Note•
After the engine management adaption has been reset on this model, the Cruise Control Switch Check Function Test must be performed (see Cruise Control Switch Check). After the adaptions have been reset, DTC 1575 (cruise control disabled until button press sequence completed) will be stored, and the cruise control disabled, until the function test is completed.

I have down loaded revised stock tunes in my 2022 Bonneville T120 and my 2022 Tiger 900 GT LRH. Both have 1575 CEL code. As both bikes are ride by wire, will this procedure work on both of these bikes ?

If you have cruise it should. The switch check is to verify the inputs to the cruise are working. Your owner's manual should also state how to do the switch check. Once the switch check is done the code clears.

your right on point

Thanks Atom. The procedure worked for the Tiger 900 GT LRH, but did not work on the Bonneville T120. The T120 only has a single button unlike the Tiger which has the rocker button for + and - speed settings. Does anybody know the correct procedure for the T120 ?

This is what Mr AI says:

To reset the cruise control on a Triumph Bonneville T120 after a TuneECU flash, the procedure is to activate all cruise control switches while the ignition is on, the engine is off, and a transmission switch (like the front brake, rear brake, or clutch switch) is activated. If the cruise control indicator light (CC light) goes out, the system has been reset.
Step-by-Step Cruise Control Reset:

1. Turn the ignition key to the ON position, but do not start the engine.
2. Ensure the cruise control is set to OFF.
3. Activate the Front Brake Switch.
4. Activate the Rear Brake Switch.
5. • Activate the Clutch Switch.
   • With the throttle in the closed position, activate the Twist Grip Switch (throttle position sensor).
   • Activate the Cruise ON/OFF Switch.
   • Activate the Cruise Accelerate Switch.
   • Activate the Cruise Decelerate Switch.

If the cruise control light turns off, the system is reset.
