Inspection Procedure

HINT:

Read freeze frame data using the 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. READ DTC OUTPUT 
   1. Connect the Techstream to the DLC3.
   2. Turn the ignition switch to ON.
   3. Turn the Techstream on.
   4. Clear DTCs after recording the freeze frame data and DTC (See DTC CHECK / CLEAR ).
   5. Turn the ignition switch off.
   6. Start the engine and allow the engine to idle.
   7. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
   8. Read DTCs.

2. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY 
   1. Disconnect the camshaft timing oil control valve assembly connector.
   2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection	Condition	Specified Condition
      1 - 2	20°C (68°F)	6.9 to 7.9 Ω

   3. Reconnect the camshaft timing oil control valve assembly connector.

3. CHECK HARNESS AND CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM) 
   1. Disconnect the camshaft timing oil control valve assembly connector.
   2. Disconnect the ECM connector.
   3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Open) 

      RESISTANCE REFERENCE
      
      

      Tester Connection	Condition	Specified Condition
      B95-1 - B31-100 (OC1+)	Always	Below 1 Ω
      B95-2 - B31-123 (OC1-)	Always	Below 1 Ω

      Standard Resistance (Check for Short) 

      RESISTANCE REFERENCE
      
      

      Tester Connection	Condition	Specified Condition
      B95-1 or B31-100 (OC1+) - Body ground	Always	10 kΩ or higher
      B95-2 or B31-123 (OC1-) - Body ground	Always	10 kΩ or higher

   4. Reconnect the camshaft timing oil control valve assembly connector.
   5. Reconnect the ECM connector.

   NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (CAMSHAFT TIMING OIL CONTROL VALVE ASSEMBLY - ECM)
