TROUBLE DIAGNOSES — Supplemental Restraint System (SRS) — Trouble Diagnoses Introduction

The SRS self-diagnosis results can be read by using "AIR BAG" warning lamp and/or CONSULT. The reading of these results is accomplished using one of two modes — "User mode" and "Diagnosis mode". The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system malfunction through the operation of the "AIR BAG" warning lamp.

The Diagnosis mode allows the technician to locate and inspect the malfunctioning part. The mode applications for the "AIR BAG" warning lamp and CONSULT are as follows:

"SELF-DIAG [CURRENT]" — A current Self-diagnosis result (also indicated by the warning lamp flashes in the Diagnosis mode) is displayed on the CONSULT screen in real time. This refers to a malfunctioning part requiring repairs.

"SELF-DIAG [PAST]" — Diagnosis results previously stored in the memory are displayed on the "CONSULT" screen. The stored results are not erased until memory erasing is executed.

"TROUBLE DIAG RECORD" — With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be displayed on the "CONSULT" screen.

"ECU DISCRIMINATED NO." — The diagnosis sensor unit for each vehicle model is assigned with its own, individual classification number. This number will be displayed on the CONSULT screen. When replacing the diagnosis sensor unit, refer to the part number for the compatibility. After installation, replacement with a correct unit can be checked by confirming this classification number on the CONSULT screen. The diagnosis sensor unit classification number varies depending on SRS configurations.

For NISSAN model K11, the diagnosis sensor unit classification numbers are as follows.

"PAS PRESENCE STATUS" mode can not be used for this vehicle. This mode is for future expanded function.
