Detection Condition

If PCM detects actual idle speed is less than expected by 100 RPM for 14 seconds, when brake pedal is depressed (brake switch is on) and steering wheel is held straight ahead (Power Steering Pressure (PSP) switch is off), PCM determines idle control system has a malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in two consecutive drive cycles. PENDING CODE is available if PCM detects malfunction condition during first drive cycle. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
