Tip Function Check

Ensure battery voltage is present at breakout box pins No. 2 and 3. Hold switch in TIP position. No voltage should be present at breakout box pin No. 1. If readings are okay, go to step 3 . If readings are not okay, disconnect cruise control switch connector. Check for voltage at cruise control switch connector terminal No. 7. If voltage is present, go to step 3 . If voltage is not present, go to next step.
Measure resistance between load side of fuse No. 22 and switch connector terminal No. 7. If resistance is greater than one ohm, repair wiring. If resistance is less than one ohm, go to next step.
Hold switch in TIP position. Measure resistance between switch terminals No. 7 and 9, then between terminals No. 7 and 10. Hold switch in ON/OFF position. Measure resistance between terminals No. 7 and 8. If any readings are greater than one ohm, replace switch. If readings are less than one ohm, go to next step.
Measure resistance between switch connector terminals and breakout box. See CRUISE CONTROL FUNCTION SWITCH CONNECTOR/BREAKOUT BOX RESISTANCE table. If any readings are greater than one ohm, repair wiring. If any readings are less than one ohm, replace cruise control module.
