Cancel switch: the indicator light goes off when the cancel switch is turned on.
2 Inspect terminal voltage(ccs)
- Remove the cruise control ecu assy with the connector being connected.
- turn the ignition switch to on.
- measure the voltage between terminals 11 (ccs) of the
cruise control ecu assy connector and the body ground
when each control switch is operated.
Ok:
3 Inspect cruise control main switch assy

5 Check harness and connector(between cruise control ecu assy and cruise control main switch assy)
- Check for open and short circuit in harness and connector between cruise control ecu assy and cruise control main switch assy
6 Input signal check(see step 1)
Check and replace cruise control ecu assy
