Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.
  1. If DTCs P0411, P0418, P2432 or P2433 are set, perform those diagnostics first.
  2. Ignition ON, observe that the AIR pump is not activated.
    • If the AIR pump is activated, test the AIR pump voltage supply circuit for a short to voltage. If the circuit tests normal, test the AIR pump relay control circuit for a short to ground. If the circuits test normal, test the relay. If the circuits and relay test normal, replace the PCM.
