CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Click here
-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON.
- Turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON.
- Turn the GTS on.
- Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher with all the accessories switched off [A].
- When the vehicle is stationery, gradually depress the accelerator pedal to increase the engine speed to 4000 rpm over a 30 second period, run the engine speed at 4000 rpm for 1 minute, then release the accelerator pedal to return to the idling speed [B].
- Repeat step [B] 3 times or more [C].
- Enter the following menus: Powertrain / Engine / Trouble Codes [D].
-
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P052400.
-
Check the DTC judgment result.
GTS Display
Description
NORMAL
- DTC judgment completed
- System normal
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system is malfunctioning.
- If the judgment result is INCOMPLETE, perform steps [B] through [D] again.
-
[A] to [D]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT
HINT:
- If the engine oil level is sufficient but a low engine oil level DTC is output, confirm with the customer whether engine oil was added after the vehicle had been driven with a low engine oil level.
- If an incorrect engine oil viscosity is used, a DTC related to low oil pressure, etc., may be stored.
- Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
|
1. |
CHECK ENGINE OIL LEVEL |
Click here
(a) Check the state of the oil level warning.
|
Result |
Proceed to |
|---|---|
|
Engine oil level is within the specified range and oil level warning is not displayed |
A |
|
Engine oil level is low and oil level warning is displayed |
B |
HINT:
If the oil level warning is not displayed even though the engine oil level is below the Low mark, or the oil level warning is displayed even though the engine oil level is within the specified range, inspect the oil level sensor and related parts.
| B |

2. |
CHECK ENGINE OIL QUALITY |
Click here
(a) Check that the engine oil is not contaminated with water, deteriorated, discolored or excessively thin.
OK:
The engine oil is not contaminated with water, deteriorated, discolored or excessively thin.
| OK |
|

OK:
There are no engine oil leaks.
HINT:
If there are engine oil leaks, perform the following steps after repairing or replacing the malfunctioning parts.
|
|
5. |
ADD ENGINE OIL |
(a) Add engine oil.
NOTICE:
Do not add engine oil to above the full level mark.
|
|

CHECK ENGINE OIL PRESSURE |
(a) Install the oil pressure gauge with adapter.
Click here
(b) Start the engine.
(c) Maintain "Coolant Temperature" at 90 to 95°C (194 to 203°F) for 3 minutes, and then read the oil pressure gauge value at 1000 rpm, 2000 rpm and 3000 rpm.

Coolant Temperature |
HINT:
- When the engine oil pressure and temperature sensor is removed, the engine oil temperature cannot be checked, so refer to "Coolant Temperature".
- Race the engine as necessary to maintain "Coolant Temperature" at 90 to 95°C (194 to 203°F).
- If maintained for 3 minutes or more, the engine oil temperature may exceed 85°C (185°F).
