OBD- II DRIVE CYCLE

All kinds of Diagnostic Trouble Codes (DTCs) can be monitored by carrying out a short drive according to the following five drive cycle patterns. In other words, doing such a drive regenerates any kind of trouble which involves illuminating the malfunction indicator lamp (SERVICE ENGINE SOON or check engine lamp) and verifies that the trouble has been eliminated [the malfunction indicator lamp (SERVICE ENGINE SOON or check engine lamp) is no longer illuminated].

caution

Two technicians should always be in the vehicle when carrying out a test.

note	Check that the DTC is not set before driving the OBD-II drive cycle. Erase the DTC with scan tool (M.U.T.-III SE) if it has been set.

SYSTEM READINESS TEST STATUS

PURPOSE

The readiness function (also referred to as I/M readiness or I/M flags) indicates if a full diagnostic check has been "Completed" (is "Ready") for each non-continuous monitor. Enhanced I/M state emission programs will use the readiness status (Codes) to see if the vehicle is ready for OBD-II testing. "Incomplete" (Not ready) codes will be one of the triggers for I/M failure.

OVERVIEW

The ECM monitors the following main diagnosis items and records whether the evaluation was completed or is incomplete. The readiness codes are established for the I/M programs, thereby confirming that the vehicles have not been tampered with by erasing the DTCs before I/M testing. The readiness codes and DTCs can be set again by erasing the codes with a scan tool (M.U.T.-III SE). For this reason, all the readiness codes must be displayed "Complete" before I/M testing.

When the monitors run and complete, the scan tool (M.U.T.-III SE) will display the readiness codes as "Complete" (General Scan Tools display as "Ready"). When the vehicle is operating normally and the OBD-II drive cycle is carried out, the readiness codes will be generated as "Complete" on the first drive cycle. For DTCs requiring two drive cycles to detect a fault, the second drive cycle is required to generate the readiness codes as "Complete" if a fault is detected during the first drive cycle. If the fault is still there after the second drive cycle, a DTC will be set.

Catalyst: P0421-00
EGR and/or VVT system: P0011-00, P0400-00, P0402-00
Evaporative emission system: P0441-00, P04EC-00, P04ED-00, P04EE-00, P04EF-00
Fuel system: P219A-00
Heated oxygen sensor (rear): P0139-00, P0140-00
Heated oxygen sensor (rear) heater: P0037-00, P0038-00
Linear air-fuel ratio sensor: P0133-00, P014C-00, P014D-00, P015A-00, P015B-00
Linear air-fuel ratio sensor heater: P0031-00, P0032-00, P0053-00

After all the readiness codes are displayed as "Complete", the technician is assured that any DTCs related to the monitor will be displayed if the system has a problem. That is why some state's I/M programs require the readiness code as "Complete" before they check for DTCs.

note	After a repair is made for a DTC, the technician should drive the OBD-II drive cycle checking that the scan tool (M.U.T.-III SE) displays all the readiness codes as "Complete".
