Turboidiot Posted August 22, 2019 Share Posted August 22, 2019 Hi have put a glide into an FG and now cruise control doesn't work, car was a manual and have bridged the clutch switch. Guessing changing the speed source somewhere might be the solution? Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted August 22, 2019 Share Posted August 22, 2019 Do you even have a working speed source? Do you have the correct gear ratios entered? Quote Link to comment Share on other sites More sharing options...

Do a DTC read with forscan and list the faults. Have you changed the torque sources at all? Turned off the torque module? Quote Link to comment Share on other sites More sharing options...
apoc Posted August 24, 2019 Share Posted August 24, 2019 I remember a similar topic in here, about gear ratios. Guy changed the ratio of a gear in his t56 and it wouldn't engage cruise, until the correct ratios were set in the tune - It seems like it might expect a particular rpm for a speed?

Nigel Posted September 23, 2019 Share Posted September 23, 2019 I wonder if the PCM is waiting for the clutch switch to actually cycle before working - just as it does with the Brake switches Quote Link to comment Share on other sites More sharing options...
