F–48 ON-BOARD DIAGNOSTIC Vehicle Speed Sensor (VSS) • Vehicle speed signal does not input after the following conditions are met: Idle Air Control (IAC) Valve • The PCM monitors idle speed. If idle speed is 1,800 rpm or below for 3 s during KOER self test, the PCM IAC system RPM lower than expected (P0506) • Actual idle speed is lower than expected by 100 rpm for 14 s, when brake pedal is depressed (brake switch is IAC system RPM higher than expected (P0507) • Actual idle speed is higher than expected by 200 rpm for 14 s, when brake pedal is depressed (brake switch is IAC valve circuit malfunction (P0511) • If the PCM detects that the PCM terminal 4G voltage is above or below threshold when IAC control duty target Power Steering Pressure (PSP) Switch • The PCM monitors PSP switch signal at the PCM terminal 1Z. If input voltage is low (switch stays on) for 1 ° C {140 ° F}, the PCM determines that the PSP switch circuit has a malfunction. PCM Configuration • No configuration data in PCM. Note • If “PCM CONFIGURATION” is successful, the PCM stored DTC P0602 and illuminates the MIL (System i • MIL goes off after three drive cycles with no failure (DTCs remain in PCM). Control module vehicle options error (P0610) • PCM data configuration error. Variable Intake-air System (VIS) Control Solenoid Valve • The PCM monitors VIS control solenoid valve control signal at the PCM terminal 4R. If the PCM turns the VIS VIS control solenoid valve circuit high input (P0662) • The PCM monitors VIS control solenoid valve control signal at the PCM terminal 4R. If the PCM turns the VIS Brake Switch • The PCM monitors changes in input voltage from the brake switch. If the PCM does not detect the PCM Clutch Switch • The PCM monitors changes in input voltage from the clutch switch. If the PCM does not detect the PCM |
