Crank (CKP) Pattern Clear/Crank (CKP) Pattern Learn
Clear/Learn Procedure (with the HDS)
1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
2. Turn the ignition switch ON (II).
3. Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting. See: Testing and
Inspection/Component Tests and General Diagnostics/DLC Circuit Troubleshooting
4. Select CRANK PATTERN in the ADJUSTMENT MENU with the HDS.
5. Select CRANK PATTERN LEARNING with the HDS, and follow the screen prompts.
Learn Procedure (without the HDS)
1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on.
2. 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 L position.
3. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 5,000 rpm down to 3,000 rpm with the
transmission in L position.
4. Repeat step 2 and 3 several times.
5. Turn the ignition switch OFF.
6. Turn the ignition switch ON (II), and wait 30 seconds. The CKP pattern learn procedure is complete.
How to End a Troubleshooting Session (required after any troubleshooting)
1. Reset the PCM with the HDS.
2. Do the PCM idle learn procedure.
3. Turn the ignition switch OFF.
4. Disconnect the HDS from the DLC.
NOTE: The PCM is part of the immobilizer system. If you replace the PCM, it will have a different immobilizer code. In order for the engine to
start, you must rewrite the immobilizer code with the HDS.
PCM Idle Learn Procedure
PCM Idle Learn Procedure
The idle learn procedure must be done so the PCM can learn the engine idle characteristics.
