Status Log

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

Connect the HDS to the data link connector.
Turn the ignition switch to ON (II).
On the HDS screen, at MAIN MENU, enter IMMOBILIZER, then select IMMOBILIZER SET-UP, select System Check, Number of keys and Status Log, then select STATUS LOG.
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.

STATUS LOG REFERENCE TABLE

Status Log 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-keyless control unit failure
B-1	ECM/PCM CODE MISMATCH (Code format normal, but code data is mismatch)	ECM/PCM was not registered correctly Low battery voltage Poor or loose terminal connections at the immobilizer-keyless control unit Communication line electrical noise
B-2	ECM/PCM MISMATCH (Code format failure)	ECM/PCM was not registered correctly Low battery voltage Poor or loose terminal connections at the immobilizer-keyless control unit Communication line electrical noise
C-1	IMOES UNIT mismatch (Code format normal, but data is mismatch)	Imoes unit was not registered Poor communication between imoes unit and immobilizer unit because of low battery voltage Poor communication between imoes unit and immobilizer unit because of electrical interference
C-2	IMOES UNIT mismatch (Code format failure)	Imoes unit was not registered correctly Poor communication between imoes unit and immobilizer unit because of low battery voltage Poor communication between imoes unit and immobilizer unit because of electrical interference
D-1	SECURITY-NET LINE PROBLEM IMOCD (S-NET) (Short to ground)	Low battery voltage Poor or loose terminal connections at the immobilizer-keyless control unit and the ECM/PCM Communication line electrical noise
D-2	SECURITY-NET LINE PROBLEM (No communication)	Blown fuse Harness open from imoes unit to immobilizer unit Poor communication between imoes unit and immobilizer unit because of low battery voltage Poor communication between imoes unit and immobilizer unit because of electrical interference Imoes unit failure Immobilizer unit failure
D-3	SECURITY-NET LINE PROBLEM IMOCD (S-NET) (Open line or ECM/PCM failure)	Open or short in the harness from the ECM/PCM to the immobilizer-keyless control unit Low battery voltage Poor or loose terminal connections at the immobilizer-keyless control unit and the ECM/PCM Communication line electrical noise
