Drive CyclePROCEDURE
It is necessary to perform the drive cycle listed below if DTC is not found in the Inspection Mode. It is possible to complete diagnosis of the DTC by performing the indicated drive cycle. After the repair for the DTC, perform a necessary drive cycle and make sure the function recovers and the DTC is recorded.
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 Clear Memory Mode, check that no DTC remains. Clear Memory Mode
3. Check the delivery (test) mode fuse is removed.
NOTE:
- Perform the drive cycle after warming up the engine except when the engine coolant temperature at engine start is specified.
- Perform the drive cycle twice if the DTC in the list is marked with *.After completing the first drive cycle, stop the engine and perform second diagnosis in same condition.
2. DRIVE CYCLE A
Diagnostic procedure:
1. Drive for 20 minutes or more at a constant speed of 80 km/h (50 MPH) or more.
2. Stop the vehicle and idle for one minute.
3. DRIVE CYCLE B
Diagnostic procedure:
1. Drive at 10 km/h (6 MPH) or more.
2. Stop the vehicle and idle for ten minutes.
4. DRIVE CYCLE C
Diagnostic procedure:
Drive according to the drive pattern described below.
5. DRIVE CYCLE E
Diagnostic procedure:
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.)
6. DRIVE CYCLE F
Diagnostic procedure:
1. Make sure that the engine coolant temperature is less than 30°C (86°F).
2. Drive according to the drive pattern described below.
NOTE:
- There is no given transition time between idling and cruising.
- Driving at constant speed only on a downhill causes smaller engine load and may result in failure to obtain a right diagnostic result.
- When the engine stops while performing drive cycle F, perform it again from the state of procedure 1).
7. 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. Subaru Select Monitor
3. If the values from step 2) satisfy the following two conditions, idle the engine for one minute.
Condition:
|Engine coolant temperature - Intake air temperature| ≤ 5°C (9°F)
NOTE:
- If the conditions are not satisfied, turn the ignition switch to OFF and wait until the parameters are satisfied.
- For CVT models, hold the select lever to "P" range or "N" range at idling, and for MT models, the shift lever in the neutral position at idling.
8. DRIVE CYCLE I
CAUTION: Be careful of the state of the battery when performing the DRIVE CYCLE I consecutively. Performing the DRIVE CYCLE I consecutively without the engine running may cause a low battery voltage and battery discharge.
NOTE:
- If it is necessary to perform DRIVE CYCLE I consecutively, drive the vehicle under the following conditions to release accumulated evaporating gas. Performing the DRIVE CYCLE I consecutively without starting the engine causes a large amount of evaporating gas to accumulate in the canister, which hinders an accurate diagnosis.
- After engine is warmed up
- Drive for 10 minutes or more at a speed of 48 km/h (30 MPH) or more (duration of drive can be an accumulation)
- To obtain an accurate diagnostic result, perform the procedures according to the following points.
- Do not refuel gas immediately before performing DRIVE CYCLE I. There will be a large amount of evaporating gas immediately after refuel, which may cause a less accurate diagnostic performance.
- Do not shake the vehicle while performing DRIVE CYCLE I. Shaking the vehicle causes evaporating gas to increase inside the fuel tank, which may cause a less accurate diagnostic performance.
- Do not perform any service operation including installation or removal of parts or connectors while performing DRIVE CYCLE I. Performing service operation could affect on the functions of related parts, which may cause a less accurate diagnostic performance.
1. Prepare the Subaru Select Monitor kit.
2. Prepare PC with Subaru Select Monitor installed.
3. Connect the USB cable to SDI (Subaru Diagnosis Interface) and USB port on the personal computer (dedicated port for the Subaru Select Monitor).
NOTE: The dedicated port for the Subaru Select Monitor means the USB port which was used to install the Subaru Select Monitor.
4. Connect the diagnosis cable to SDI.
5. Connect SDI to data link connector located in the lower portion of the instrument panel (on the driver's side).
CAUTION: Do not connect the scan tools except for Subaru Select Monitor and general scan tool.
6. Start the PC.
7. Turn the ignition switch to ON (engine OFF) and run the "PC application for Subaru Select Monitor".
8. On [[Main Menu]] display, select {Each System Check}.
9. On [[System Selection Menu]] display, select {Engine Control System}.
10. Click the [OK] button after the information of engine type has been displayed.
11. On [[Engine Diagnosis]] display, select {OBD System}.
12. On [[OBD Menu]] display, select {Evaporative System Leak Test}.
13. On [[Evaporative System Leak Test]] display, select {Evaporative System Leak Test}.
14. On [[Evaporative System Leak Test is running. Press Cancel to exit this function.]] display, click the [OK] button to perform evaporative system leak test.
15. When [[Conditions have been enabled to control this function. Turn the ignition switch off to terminate the test.]] display appears, wait for 30 minutes without clicking the [OK] button.
CAUTION: Do not leave the vehicle for an extended period of time after the test is complete. This may cause early deterioration of the battery or discharged battery.
NOTE:
- Clicking the [OK] button bring the [[Evaporative System Leak Test]] display back, although the test is continuing.
- The Subaru Select Monitor screen does not change after the evaporative system leak test is complete or when the test is aborted by turning off the ignition switch.
- If the [[Test conditions are not correct]] display appears, check that the values of [[Coolant Temp.]] and [[Intake Air Temp.]] are within the specified range using Subaru Select Monitor. If the conditions are satisfied, make the necessary preparation for the drive cycle again.
16. After 30 minutes passed from the start of step 14), click the [OK] button to return to the [[Evaporative System Leak Test]] display.
17. Click buttons until the [[OBD Menu]] display appears, then select {Result of on-board monitor test}.
18. In the {Result of on-board monitor test}, check TID $C1 - $CA of MID $3C.
19. When the evaporative system leak test is completed correctly, read the temporary codes with the ignition switch turned to ON position. If the DTC is recorded, check the appropriate DTC. Read Diagnostic Trouble Code (DTC)
NOTE: The temporary code will be cleared by turning ignition switch to OFF.
9. DRIVE CYCLE J
1. Idle the engine for 15 minutes or more.
2. Turn the ignition switch to OFF.
3. After 6 hours passed from the start of step 2), read the temporary code using the Subaru Select Monitor. Read Diagnostic Trouble Code (DTC)
