Code 36, Idle Speed Actuator Fault - A/T: Notes
Control module grounds solenoid circuit when coolant temperature is within range to enable solenoid, allowing vacuum to retract solenoid actuator. This lowers idle speed to controlled IAC idle specification.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- Checks if vacuum source is present.
- Checks to see if actuator is commanded on.
- Checks for power, ground and proper connections at actuator solenoid.
- Checks for open ground circuit.
- Checks for open driver circuit or faulty control module.
