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 battery voltage is more than 12 V and fuel remains 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 for any remaining unresolved trouble data. Reading and Clearing Diagnostic Trouble Codes
3. Disconnect the delivery (test) mode connector.
NOTE:
- Except for the water temperature specified items 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.
P0125-P2103:
3. DRIVE CYCLE B (10 MINUTES IDLING)
NOTE: Drive the vehicle in more than 10 km/h (6 MPH) before diagnosis.
P0126-P2103:
4. DRIVE CYCLE C (DRIVE ACCORDING TO THE FOLLOWING DRIVE PATTERN)
P0030-P2103:
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 more than 10 l (2.6 US gal, 2.2 Imp gal) and the battery voltage is more than 10.9 V.
3. Make sure that the engine coolant temperature rises for more than 10 °C (18 °F) from the level of engine starting and is also above 75 °C (167 °F).
4. Idle the engine for 120 seconds or more in the condition of step 3.
Stuck Diagnosis
1. Make sure that the battery voltage is more than 10.9 V.
2. Perform the Clear Memory Mode. Reading and Clearing Diagnostic Trouble Codes
3. Drive the vehicle for the distance equal to the fuel of 50 l (13.2 US gal, 11 Imp gal).
NOTE:
- It is acceptable to drive the vehicle intermittently.
- Do not disconnect the terminal of battery during diagnosis. (Data will be cleared when disconnecting the battery terminals.)
P0181:
6. DRIVE CYCLE E
1. Make sure that the battery voltage is 10.9 V or more.
2. Perform the Clear Memory Mode. Reading and Clearing Diagnostic Trouble Codes
3. Drive the vehicle for the distance equal to the fuel of 30 l (7.9 US gal, 6.6 Imp gal).
NOTE:
- It is acceptable to drive the vehicle intermittently.
- Do not disconnect the terminal of battery during diagnosis. (Data will be cleared when disconnecting the battery terminals.)
P0461:
7. DRIVE CYCLE F
1. Check that the engine coolant temperature at engine start is less than 30 °C (86 °F).
2. Start the engine, and warm it up until engine coolant temperature increases over 95 °C (203 °F).
3. Idle the engine for more than 10 minutes in the condition of step 2.
NOTE: Do not disconnect the terminal of battery during diagnosis. (Data will be cleared by disconnecting the battery terminals.)
P0111:
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 °C (176 °F).
3. Start the engine and warm-up engine until coolant temperature is 40 °C (104 °F).
NOTE: Do not let engine coolant temperature drop below 5 °C (41 °F).
4. Start the engine and warm-up engine until coolant temperature is 80 °C (176 °F).
5. Start the engine and warm-up engine until coolant temperature is 40 °C (104 °F).
NOTE: Do not let engine coolant temperature drop below 5 °C (41 °F).
6. Start and idle the engine.
P0410:
9. DRIVE CYCLE H
1. Perform the Clear Memory Mode. Reading and Clearing Diagnostic Trouble Codes
2. Read the engine coolant temperature, intake air temperature and fuel temperature with ignition switch ON. Subaru Select Monitor
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 value does not meet the conditions, turn the ignition switch to OFF and wait until it meets.
- Start the engine in P range (AT model) or in N position (MT model).
4. Idle the engine for one minute in the condition of step 3.
