• Is there continuity?
Yes
Repair or replace short to ground, then go to Step 6.
No
Go to the next step.
4
INSPECT CRUISE CONTROL SWITCH SIGNAL CIRCUIT FOR SHORT TO POWER
• Turn the engine switch to the ON position (Engine off).
• Inspect the voltage between cruise control switch terminal B (wiring harness-side) and body ground.
• Is the voltage less than 1.0 V?
Yes
Go to the next step.
No
Repair or replace short to power supply, then go to Step 6.
5
INSPECT CRUISE CONTROL SWITCH OPERATION
• Inspect the cruise control switch.
