Monitors, Trips, Drive Cycles and Readiness Codes
OBD II Drive CycleNOTE:
- Disconnecting the battery will reset the memory. Do not disconnect the battery during and after this procedure.
- Vehicle speed and engine speed detected by the Powertrain Control Module (PCM) may differ from that indicated by the speedometer and the tachometer. Check the vehicle speed and engine speed during driving mode by using the SST NGS.
- If the OBD II system check is not completed while the drive cycle procedure is carried out, the following cause is guessed.
- The OBD II system detects the malfunction.
- The drive cycle procedure is not completed correctly.
OBD-II Drive Cycle Procedure (Mode 1) Graph:
MODE 1
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (headlight, blower motor and rear window defroster) and A/C load are off.
3. Verify that the initial ignition timing and the initial idle speed are within the specification.
4. Is not as specified, adjust the ignition timing and idle speed.
5. Verify that terminals TEN and GND of the data link connector are not connected.
6. Carry out no-load racing at the specified speed. Race the engine for more than 5 seconds at each time.
7. Idle the engine for more than 20 seconds with the electric cooling fan (if equipped) stopped.
OBD-II Drive Cycle Procedure (Mode 2) Graph:
MODE 2
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (headlight, blower motor and rear window defroster) and A/C load are off.
NOTE: Driving mode before the constant speed driving is not specified.
3. Drive the vehicle at the constant speed of 79-95 km/h (49-59 mph) (MTX), 76-98 km/h (47-61 mph) (ATX) for one minute (MTX: 5th gear, ATX: D range).
OBD-II Drive Cycle Procedure (Mode 3) Graph:
MODE 3
1. Start the engine and warm it up completely.
2. Verify that all electrical loads (headlight, blower motor and rear window defroster) and A/C load are off.
3. Drive the vehicle at the constant speed of above 65 km/h (40 mph) for one minute after above 300 seconds from engine start.
4. Drive the vehicle at the constant speed 68-100 km/h (42-62 mph) (MTX), 73-104 km/h (45-65 mph) (ATX) for three minutes. (MTX: 5th gear, ATX: D range)
NOTE: Driving mode before the constant speed driving is not specified.
