How to Read DTC and 1st Trip DTC

DTC and 1st trip DTC can be read by the following methods.

Without Scan Tools
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 DTCs are controlled by NISSAN.

WITH CONSULT OF GENERIC SCAN TOOL
2. CONSULT or GST (Generic Scan Tool) Examples: P0340, P1320, P0705, P0750, etc.
These DTCs are prescribed by SAE J2012.
(CONSULT also displays the malfunctioning component or system.)
- 1st trip DTC No is the same as DTC No.
- Output of a DTC indicates a malfunction. However, Mode II and GST do not indicate whether the malfunction is still occurring or has occurred in the past and has returned to normal.
CONSULT can identify malfunction status as shown below. Therefore, using CONSULT (if available) is recommended.




A sample of CONSULT display for DTC is shown at left. DTC or 1st trip DTC of a malfunction is displayed in SELF-DIAGNOSTIC RESULTS mode of CONSULT. Time data indicates how many times the vehicle was driven after the last detection of a DTC.
If the DTC is being detected currently, the time data will be "0".




If a 1st trip DTC is stored in the ECM, the time data will be "[1t]".
