Inspection Procedure

HINT:

Read freeze frame data using Techstream. 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. CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P1455) 
   1. Connect Techstream to the DLC3.
   2. Turn the power switch ON (IG).
   3. Turn the tester ON.
   4. Enter the following menus: Powertrain / Engine and ECT / Trouble Code.
   5. Read DTCs.
