- *1: Clear timing is at the moment OK is detected.
- *2: Clear timing is when the same malfunction is detected in the 2nd trip.
|
*1: |
When the same malfunction is detected in two consecutive trips, MIL will light up. |
*2: |
MIL will turn OFF after vehicle is driven 3 times (pattern B) without any malfunctions. |
*3: |
When the same malfunction is detected in two consecutive trips, the DTC and the freeze frame data will be stored in ECM. |
|
*4: |
The DTC and the freeze frame data will not be displayed any longer after vehicle is driven 80 times (pattern C) without the same malfunction. (The DTC and the freeze frame data still remain in ECM.) |
*5: |
When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data will be stored in ECM. |
*6: |
The 1st trip DTC and the 1st trip freeze frame data will be cleared at the moment OK is detected. |
|
*7: |
When the same malfunction is detected in the 2nd trip, the 1st trip freeze frame data will be cleared. |
*8: |
1st trip DTC will be cleared when vehicle is driven once (pattern C) without the same malfunction after DTC is stored in ECM. |
Driving Pattern B
Refer to Driving Pattern .
Driving Pattern C
Refer to Driving Pattern .
Example:
If the stored freeze frame data is as per the following:
Engine speed: 850 RPM, Calculated load value: 30%, Engine coolant temperature: 80 deg.C (176 deg.F)
To be satisfied with driving pattern C, the vehicle should run under the following conditions:
Engine speed: 475 - 1, 225 RPM, Calculated load value: 27 - 33%, Engine coolant temperature: more than 70 deg.C (158 deg.F)

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
