23. Turn the ignition switch ON (II).
24. Slowly press the accelerator pedal to the floor.
25. Check for Pending or Confirmed DTCs with the HDS. Is DTC P2118 indicated? YES - Check for poor connections or loose terminals at the throttle body and the ECM. If the ECM was updated, substitute a known-good ECM (see «SUBSTITUTING THE ECM»(ref-379880-S34678618312010121600000) ), then go to step 22 . If the ECM was substituted, go to step 1. NO - If the ECM was updated, troubleshooting is complete. If the ECM was substituted, replace the original ECM (see «ECM REPLACEMENT»(ref-355119-S26942562032010012000000) ). If any other Pending or Confirmed DTCs are indicated, go to the indicated DTCs troubleshooting.
