Status Log

If you suspect there is a immobilizer system problem, check the status log in the HDS.

1. Connect the HDS to the data link connector.
2. Turn the ignition switch to ON (II).
3. On the HDS screen, at MAIN MENU, enter IMMOBILIZER, then select IMMOBILIZER SET-UP, select IMMOBILIZER INFORMATION, then select STATUS LOG.
4. Check the STATUS LOG count. Troubleshoot the status with the highest count first. If no counts are listed, the immobilizer system is OK. Continue with normal symptom troubleshooting.
   PROBABLE CAUSE REFERENCE CHART
   
   

   Status Loq No.	Detected Item	Probable Cause
   A-1	KEY CODE MISMATCH (Code format normal, but code data is mismatch)	The key was not registered Interference from metal such as key chains Low battery voltage
   A-2	KEY CODE MISMATCH (Code format failure)	Ignition switch was turned to ON (II) with another type of immobilizer key or aftermarket key Interference from metal such as key chains Low battery voltage
   A-3	KEY CODE MISMATCH (No key code or non-immobilizer key)	Ignition switch was turned to ON (II) with another type of immobilizer key or aftermarket key Interference from metal such as key chains Low battery voltage Key failure Immobilizer control unit-receiver failure
   B-1	PCM CODE MISMATCH (Code format normal, but code data is mismatch)	PCM was not registered correctly Low battery voltage Poor or loose terminal connections at the immobilizer control unit-receiver Communication line electrical noise
   B-2	PCM MISMATCH (Code format failure)	PCM was not registered correctly Low battery voltage Poor or loose terminal connections at the immobilizer control unit-receiver Communication line electrical noise
   C-1	IMOES UNIT mismatch (Code format normal, but data is mismatch)	Imoes unit was not registered The communication was not good between imoes unit and immobilizer unit by battery voltage low The communication was not good between imoes unit and immobilizer unit by influence of some noise
   C-2	IMOES UNIT mismatch (Code format failure)	Imoes unit was not registered correctly The communication was not good between imoes unit and Immobilizer control unit-receiver by because of low battery voltage The communication was not good between imoes unit and Immobilizer control unit-receiver because of electrical interference
   D-1	IMOCD (S-NET) LINE PROBLEMIMOCD (S-NET) (Short to ground)	Low battery voltage Poor or loose terminal connections at the immobilizer control unit-receiver and the PCM Communication line electrical noise
   D-2	IMOCD (S-NET) LINE PROBLEM (No communication)	Blown fuse Harness open from imoes unit to immobilizer control unit-receiver The communication was not good between imoes unit and Immobilizer control unit-receiver by because of low battery voltage The communication was not good between imoes unit and immobilizer control unit-receiver because of electrical interference Imoes unit failure Immobilizer control unit-receiver failure
   D-3	IMOCD (S-NET) LINE PROBLEM IMOCD (S-NET) (Open line or PCM failure)	Open or short in the harness from the PCM to the immobilizer control unit-receiver Low battery voltage Poor or loose terminal connections at the immobilizer control unit-receiver and the PCM Communication line electrical noise
