EC-894
[YD (WITH EURO-OBD)]
ON BOARD DIAGNOSTIC (OBD) SYSTEM
*1: 1st trip DTC No. and 2nd trip DTC No. are the same as DTC No.
*2: This number is prescribed by ISO 15031-6.
DTC AND 1ST/2ND TRIP DTC
The number of 1st/2nd trip DTC is the same as the number of DTC.
When a malfunction is detected during 1st trip, 1st trip DTC is stored in the ECM memory. MI does not illumi-
nate at this time. When the same malfunction is detected in the next trip (2nd trip), 2nd trip DTC is stored in the
ECM memory and 1st trip DTC is cleared from the ECM memory. MI does not illuminate at this time. In addi-
tion, DTC is stored in the ECM memory and MI lights up when the same malfunction is detected during the fol-
lowing consecutive trip (3rd trip).
The procedure for erasing DTC, 1st trip DTC, and 2nd trip DTC from the ECM memory is described in EC-895,
"HOW TO ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION" .
For malfunctions in which 1st/2nd trip DTC are displayed, Refer to EC-892, "
Emission-related Diagnostic Infor-
mation" .
1st/2nd trip DTC is specified in Mode 7 of ISO15031-5. 1st/2nd trip DTC detection occurs without lighting up
MI and therefore does not warn the driver of a malfunction.
When 1st/2nd trip DTC is detected, check, print out or write down, and erase 1st/2nd trip DTC as specified
with step II of Work Flow, refer to EC-902, "
WORK FLOW" . Then perform DTC Confirmation Procedure or
Overall Function Check to try to duplicate the malfunction. If the malfunction is duplicated, it is necessary to
investigate the cause again.
How to Read DTC and 1st/2nd Trip DTC
DTC and 1st/2nd trip DTC can be read by the following procedures.
