Drive CyclePROCEDURE
For the troubleshooting, there are seven driving patterns of drive cycles A to G. 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 battery voltage is more than 12 V and fuel remains half [20 to 40 l (5.3 to 10.6 US gal, 4.4 to 8.8 Imp gal)].
2. Disconnect the test mode connectors.
NOTE:
- Perform the diagnosis after warming up the engine except when the engine coolant temperature at starting is specified.
- Perform the diagnosis twice if the DTC marked with *. After completing the first diagnosis, stop the engine and perform second diagnosis in same condition.
P0125-P2103:
2. DRIVE CYCLE A - DRIVE THE VEHICLE WITH 80 KM/H (50 MPH) FOR 20 MINUTES, AND THEN IDLE THE ENGINE FOR A MINUTE.
P0126-P2103:
3. DRIVE CYCLE B - 10 MINUTES IDLING
NOTE: Drive the vehicle in more than 10 km/h (6 MPH) before diagnosis.
P0030-P2103:
4. DRIVE CYCLE C - DRIVE THE VEHICLE WITH FOLLOWING DRIVE PATTERNS
5. DRIVE CYCLE D
Drift Diagnosis
1. Check that the engine coolant temperature at engine start is 30 degrees C (86 degrees F) or less.
2. Check that the battery voltage is more than 10.9 V and that more than 10 l (2.6 US gal, 2.2 Imp gal) of fuel remains.
3. Start the engine, and check that the engine coolant temperature increases over 10 degrees C (18 degrees F), and reaches 75 degrees C (167 degrees F) or more, when the engine is warmed up.
4. After the engine has reached the state of procedure 3), idle the engine for more than 120 seconds.
Stuck Diagnosis
1. Check that the battery voltage is over 10.9 V.
2. Perform the Clear Memory Mode. Clearing Diagnostic Trouble Codes
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 when disconnecting the battery terminals.)
6. DRIVE CYCLE E
1. Check that the battery voltage is over 10.9 V.
2. Perform the Clear Memory Mode. Clearing Diagnostic Trouble Codes
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 when disconnecting the battery terminals.)
7. DRIVE CYCLE F
1. Check that the engine coolant temperature at engine start is 30 degrees C (86 degrees F) or less.
2. Warm up the engine until the engine coolant temperature exceeds 95 degrees C (203 degrees F) from engine start.
3. After the engine has reached the state of procedure 2), idle the engine for more than 10 minutes.
NOTE: Do not disconnect the battery terminals while diagnosing. (Data will be cleared when disconnecting the battery terminals.)
8. DRIVE CYCLE G
1. Remove the battery negative terminal, and reconnect after 10 seconds have passed.
2. Start the engine and warm-up engine until coolant temperature is 80 degrees C (176 degrees F).
3. Start the engine and warm-up engine until coolant temperature is 40 degrees C (104 degrees F).
NOTE: Do not let engine coolant temperature drop below 5 degrees C (41 degrees F).
4. Start the engine and warm-up engine until coolant temperature is 80 degrees C (176 degrees F).
5. Start the engine and warm-up engine until coolant temperature is 40 degrees C (104 degrees F).
NOTE: Do not let engine coolant temperature drop below 5 degrees C (41 degrees F).
P0410-P2443:
6. Start and idle the engine.
