Drive CyclePROCEDURE
For the troubleshooting, there are driving patterns described below. Driving in the specified pattern allows to diagnose malfunctioning items listed below. After the repair of the following trouble items, be sure to drive the vehicle with the specified drive patterns to check whether the function is resumed correctly.
1. PREPARATION FOR DRIVE CYCLE
1. Check that the battery voltage is 12 V or more and fuel remains approx. half [20 - 40 l (5.3 - 10.6 US gal, 4.4 - 8.8 Imp gal)].
2. After performing the diagnostics and clearing the memory, check that no DTC remains.
3. Disconnect the delivery (test) mode connector.
NOTE:
- Except for the water temperature specified at starting, be sure to carry out the diagnosis after the engine is warmed up.
- Perform the diagnosis twice if the DTC marked with *. After completing the first diagnosis, stop the engine and perform second diagnosis in same condition.
2. DRIVE CYCLE A - DRIVE THE VEHICLE WITH 80 KM/H (50 MPH) FOR 20 MINUTES, AND THEN IDLE THE ENGINE FOR A MINUTE
3. DRIVE CYCLE B - 10 MINUTES IDLING
NOTE: Drive the vehicle at 10 km/h (6 MPH) or faster before diagnosis.
4. DRIVE CYCLE C - DRIVE THE VEHICLE WITH FOLLOWING DRIVE PATTERNS
5. DRIVE CYCLE D
Drift Diagnosis
1. Make sure that the engine coolant temperature at engine starting is less than 30 °C (86 °F).
2. Make sure that fuel remains 10 l (2.6 US gal, 2.2 Imp gal) or more and the battery voltage is 10.9 V or more.
3. Start the engine, and check that the engine coolant temperature increases by 10 °C (50 °F) or more, and reaches 75 °C (167 °F) or more, when the engine is warmed up.
4. After the engine has reached the state of procedure 3), idle the engine for 120 seconds or more.
Stuck Diagnosis
1. Make sure that the battery voltage is 10.9 V or more.
2. Perform the Clear Memory Mode. Clear Memory Mode
3. Drive for approximately 50 l (13.2 US gal, 11 Imp gal) of fuel.
NOTE:
- It is acceptable to drive the vehicle intermittently.
- Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the battery terminals.)
6. DRIVE CYCLE E
1. Make sure that the battery voltage is 10.9 V or more.
2. Perform the Clear Memory Mode. Clear Memory Mode
3. Drive for approximately 30 l (7.9 US gal, 6.6 Imp gal) of fuel.
NOTE:
- It is acceptable to drive the vehicle intermittently.
- Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the battery terminals.)
7. DRIVE CYCLE F
1. Make sure that the engine coolant temperature at engine starting is less than 30 °C (86 °F).
2. Start the engine, and warm it up until engine coolant temperature reaches to 95 °C (203 °F) or more.
3. Idle the engine for 10 minutes or more in the condition of step 2.
NOTE: Do not disconnect the battery terminals while diagnosing. (Data will be cleared by disconnecting the battery terminals.)
8. DRIVE CYCLE H
1. Perform the Clear Memory Mode. Clear Memory Mode
2. With the ignition switch ON, read the engine coolant temperature, intake air temperature and fuel temperature.
3. If the values from step 2) satisfy the following two conditions, start the engine.
Condition:
|Engine coolant temperature - intake air temperature | ≤ 5 °C (41 °F)
|Engine coolant temperature - fuel temperature | ≤ 2 °C (36 °F)
NOTE:
- If the conditions are not satisfied, turn the ignition switch to OFF and wait until the parameters are satisfied.
- Start AT vehicles in the "P" range, and MT vehicles in the neutral position.
4. Idle the engine for 1 minute under the conditions in step 3)
