Caution / Notice / Hint

HINT: 

• If no problem is found through this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
• The engine speed can be checked by using the Techstream. To perform the check, follow the procedures below:
  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG).
  3. Turn the Techstream on.
  4. Put the engine in inspection mode (maintenance mode).

     Refer to INSPECTION MODE PROCEDURE [10/2015 - ]

  5. Start the engine.
  6. Enter the following menus: Powertrain / Engine and ECT / Data List / Engine Speed.
  1. The engine speed may be indicated as zero despite the engine running normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft position sensor output voltage is insufficient.
• Read freeze frame data using the Techstream. The ECM assembly records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
