Note. For connector terminal ID, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector for damaged or pushed out terminals. Repair as necessary. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) . If PCM connector terminals are okay, go to next step. NOTE: For next step, see «IAC DRIVER CIRCUIT ID»(ref-576-S25661866302000030800000) table for IAC motor connector wire color identification and «PCM CONNECTOR WIRE IDENTIFICATION»(ref-576-S13268681902000030800000) table.
- Using an ohmmeter, check resistance of IAC motor driver No. 4 circuit between IAC motor connector and PCM connector terminal No. 58. If resistance is 5 ohms or more, repair open in IAC motor driver No. 4 circuit. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) . If resistance is less than 5 ohms, replace PCM. Perform «TEST VER-5A: ROAD TEST FOR OBD-II TROUBLE CODES»(ref-576-S06971814902000030800000) .
