electronics help needed
Gadabout:
Hi, have just checked the diagnostic pages and what I have posted is the same as the pages, have attached photo
Thanks
Mark
Gadabout:
Sorry that should have been resized, not sure how to that on this old iPad 😟

Hi Mark,
You're right but then I can't work it out! I think it's not just a simple divider and you may be better wiring in a 100k potentiometer as has already been suggested and seeing what resistance is needed to arrive at correct voltages.
Phil.

Resized for you
John Swift:
by combining the circuit diagram with the info in the manual
as the main switch on the cruise control grounds the ECU CMS terminal 19
and cancel , set/coast & resume/accel switches selects a resistance to ground the ECU
the only way for the voltages to agree with the table in tlhe manual is the ECU inputs to have pull up resistors built into the ECU
