12. Open the SCS with the HDS.
13. Turn the ignition switch ON (II).

14. Manually input the VIN to the PCM with the HDS.
15. Update the PCM if it does not have the latest software.
16. Select the IMMOBI SYSTEM 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.
Do the idle learn procedure whenever you do any of these actions:
-
Replace PCM.
-
Reset PCM.
-
Update PCM.
-
Clean or replace the throttle body.
NOTE: Erasing DTCs with the HDS does not require you to do the idle learn procedure.
Procedure
1. Make sure all electrical items (A/C, audio, rear window defogger, lights, etc.) are off.
2. Reset the PCM with the HDS.
3. Turn the ignition switch ON (II), and wait 2 seconds.
4. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on, or until the engine coolant
temperature reaches 194 °F (90 °C).
5. Let the engine idle for about 5 minutes with the throttle fully closed.
NOTE: If the radiator fan comes on, do not include its running time in the 5 minutes.
