How to Read DTC and 1st Trip DTC
OBD-II DIAGNOSTIC TROUBLE CODE (DTC)How to read DTC and 1st trip DTC:
DTC and 1st trip DTC can be read by the following methods.
1. The number of blinks of the malfunction indicator lamp in the Diagnostic Test Mode 11 (Self-Diagnostic Results) Examples: 1101, 1102, 1103, 1104, etc. For details, refer to Computers and Control Systems.
These DTCs are controlled by NISSAN.
2. CONSULT-II or Generic Scan Tool (GST) Examples: P0705, P0710, P0720, P0725, etc.
These DTCs are prescribed by SAE J2012.
(CONSULT-II also displays the malfunctioning component or system.)
- 1st trip DTC No. is the same as DTC No.
- Output of the diagnostic trouble code indicates 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-II can identify them as shown. Therefore, using CONSULT-II (if available) is recommended.
A sample of CONSULT-II display for DTC is shown. DTC or 1st trip DTC of a malfunction is displayed in SELF-DIAGNOSTIC RESULTS mode for "ENGINE" with CONSULT-II. 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 "245".
