How to Troubleshoot the Fuel and Emissions Systems
  1. Remove the bolts (D).
  1. Disconnect ECM/PCM connectors A, B, and C, then remove the ECM/PCM (E).
    NOTE: ECM/PCM connectors A, B, and C have symbols (A=□, B=△, C=○) embossed on them for identification.
  1. Install a known-good ECM/PCM in the reverse order of removal.
  1. Turn the ignition switch to ON (II).
    NOTE: DTC P0630 ‘‘VIN Not Programmed or Mismatch'' may be stored because the VIN has not been programmed into the ECM/PCM; ignore it, and continue this procedure.
  1. Manually input the VIN to the ECM/PCM with the HDS.
  1. Select the IMMOBI SYSTEM with the HDS.
  1. Enter the immobilizer code using the ECM/PCM replacement procedure in the HDS; it allows you to start the engine.
  1. Select the PGM-FI system and reset the ECM/PCM with the HDS.
  1. Update the ECM/PCM if it does not have the latest software.
  1. Do the ECM/PCM idle learn procedure.
  1. Do the CKP pattern learn procedure.
  1. AT: Do the accelerator pedal kick down click system learn procedure.
