CKP Pattern Clear/CKP Pattern Learn Procedure

NOTE:

Clearing the DTCs with the HDS does not require you to do this procedure.

The PCM memorizes the learning status in its memory after passed an hour from turning the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode. If you need to disconnect the battery terminals before memorizing the learning status in the PCM, jump the SCS line with the HDS, and wait 60 seconds, then disconnect the battery terminals.

Clear/Learn Procedure (with the HDS)

1.	HDS - Connect

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, but do not start the engine.

Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.

Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting.

2.	CKP Pattern - Clear/Learn

Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS.

Select CRANK PATTERN CLEAR with the HDS, and clear the CKP pattern.

Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts.

Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

Jump the SCS line with the HDS.

Wait 60 seconds, and exit the SCS mode with the HDS.

Learn Procedure (without the HDS)

1.	CKP Pattern - Learn

Start the engine. Hold the engine speed at 3,000 rpm without load (A/T and CVT in P or N, M/T in neutral) until the radiator fan comes on.

Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm down to 1,000 rpm with the transmission in 2nd.

Repeat step 2 several times.

Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, and wait an hour. The CKP pattern learn procedure is complete.
