Drive CyclePROCEDURE
For the troubleshooting, there are driving patterns described. Driving in the specified pattern allows to diagnose malfunctioning items listed. 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 clearing the memory, check for any remaining unresolved trouble data. Reading and Clearing Diagnostic Trouble Codes
3. Disconnect the 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 diagnosis twice about DTCs with * mark. After the first diagnosis is completed, stop the engine and perform the second diagnosis under the 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 (TEN 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)
P0026-P2103:
5. DRIVE CYCLE D
DRIFT DIAGNOSIS
1. Check that the engine coolant temperature at engine start is less than 30 °C (86 °F).
2. Make sure that fuel remains 9.0 l (2.4 US gal, 2.0 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. Idle the engine for 120 seconds or more in the condition of step 3.
STUCK DIAGNOSIS
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 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. Warm-up the engine until engine coolant temperature rises above 95 °C (203 °F) after starting the engine.
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 when disconnecting the battery terminals.)
P0111:
8. 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.
