Inspection with CONSULT-II (Self-Diagnosis)

WARNING: This page is about a different car, the 2004 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

SELF-DIAGNOSIS RESULT CHECK

Connect CONSULT-II and select "IPDM E/R" on the Diagnosis System Selection screen.
Select "SELF-DIAG RESULTS" on the diagnosis mode selection screen.
Check display content in self-diagnosis results.

SYMPTOM CHECK REFERENCE

Diagnosis item	Data monitor display contents
Diagnosis item	Normal	Error (example)
CAN CIRC 1	OK	UNKWN
CAN CIRC 2	OK	UNKWN
CAN CIRC 3	OK	UNKWN
CAN 1 STAT	0	1 - 40
CAN 2 STAT	0	1 - 40
CAN 3 STAT	0	1 - 40

NOTE: CAN status indicates the condition of the CAN communication judged by each signal input.

Normal: If no problems were found in the past, CAN status indicates "0". If the system is presently operating properly, but had a malfunction in the past, the CAN status will indicate "39-1".
Malfunction: If there is a malfunction, CAN indicates "40".

After the system returns to its normal operating condition, every time the ignition switch is cycled (turned OFF from ON), a value will be removed from the counter (i.e. "39"->"38"->"37"..."1"). If a malfunction is detected again, CAN status indicates "40". (Although the system has returned to normal operating condition, "0" is not immediately indicated. To reset, select and press "ERASE" on the "SELF-DIAGNOSIS" screen.)
