Idle Air Control Motor

The Powertrain Control Module (PCM) operates the idle air control motor through 4 circuits - K39, K40, K59, and K60. Each circuit connects to separate cavities in the PCM connector.
- Circuit K39 connects to cavity 15 of the PCM connector and cavity 1 of the IAC motor connector.
- Circuit K4O connects to cavity 35 of the PCM connector and cavity 3 of the IAC motor connector.
- Circuit K59 connects to cavity 34 of the PCM connector and cavity 4 of the IAC motor connector.
- Circuit K6O connects to cavity 14 of the PCM connector and cavity 2 of the IAC motor connector.
