  3. ECM
УКАЗАНИЕ:
  1. These DTCs are set when the engine idles for approximately 15 seconds.
  2. If DTC P0201 is displayed, check the No. 1 injector circuit.
  3. If DTC P0202 is displayed, check the No. 2 injector circuit.
  4. If DTC P0203 is displayed, check the No. 3 injector circuit.
  5. If DTC P0204 is displayed, check the No. 4 injector circuit.

INSPECTION PROCEDURE

УКАЗАНИЕ:
Read freeze frame data using an intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
1.READ OUTPUT DTC (DTC P0201, P0202, P0203, P0204 AND/OR P2146)
  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to the ON position.

  1. Turn the tester on.

  1. Enter the following menu items: Powertrain / Engine and ECT / DTC.

  1. Read the DTCs.
