How to Read DTC, How to Erase DTC

HOW TO READ DTC (Overview)
The diagnostic trouble code can be read by the following methods.
(Either code for the 1st trip or the 2nd trip can be read.)
1. The number of blinks of the malfunction indicator lamp in the Diagnostic Test Mode II (Self-Diagnostic Results) Examples: 0101, 0201,1003,1104, etc.
These DTC's are controlled by NISSAN.
2. CONSULT or GST (Generic Scan Tool) Examples: P0340, P1320, P0705, P0750, etc. These DTC's are prescribed by SAE J2012.
- Output of the trouble code means that the indicated circuit has a malfunction. However, in case of the Mode II and GST they do not indicate whether the malfunction is still occurring or occurred in the past and returned to normal.
CONSULT can identify them. Therefore, using CONSULT (if available) is recommended.

HOW TO ERASE DTC (Overview)
The diagnostic trouble code can be erased by the following methods.
Selecting "ERASE" in the "SELF DIAG RESULTS" mode with CONSULT
Selecting Mode 4 with GST (Generic Scan Tool).
Changing the diagnostic test mode from Diagnostic Test Mode II to Mode I.
- If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
- When you erase the DTC, using CONSULT or GST is easier and quicker than switching the diagnostic test modes.
