CONDITION

  • MIL on.
  • One or more of the following DTCs are stored:
    • DTC P0300  (Random/Multiple Cylinder Misfire Detected).
    • DTC P0301 - P03010  (Cyl.1 Misfire Detected - Cyl.10 Misfire Detected).

TECHNICAL BACKGROUND

Low fuel quality in combination with a short distance driving cycle allows hydrocarbons to form carbon deposits. Deposits interrupt tumble for efficient fuel/air mixture, causing cold start misfire.

PRODUCTION SOLUTION

Not applicable.

SERVICE

  1. Add fuel additive G 001 700 03 or G 001 770 A2  directly into the fuel tank, following the mix ratio. For example, 120 ml per 30 liters gasoline, 300 ml per 20 gallons of gasoline.
  2. Drive the car 60 miles. Note in and out mileage on RO.
  3. Check for cold start misfire at the next cold start.

    Tip:  This method was proven to be very effective when carbon deposits on the injectors are the root cause.

    If misfire discontinues, carbon on the injectors was causing misfire. The repair is successful and complete.

  4. After repair, give one bottle of fuel additive G17 to the customer. Instruct the customer to add the fuel additive to a full fuel tank after 3,000 miles.
  5. Please advice the customer to use Top Tier fuel. (See TSB 2014753 .)

CONDITION

  • MIL on.
  • Rough idle.
  • One or more of the following DTCs are stored:
    • DTC P0300  (Random/Multiple Cylinder Misfire Detected).
    • DTC P0301 - P0312  (Cyl.1 Misfire Detected - Cyl.12 Misfire Detected).
  • Engine may have reduced performance without significant loss of power or stalling.

TECHNICAL BACKGROUND

Misfire faults causing MIL illumination can occur for a number of different reasons not directly related to ignition coil operation. Proper GFF misfire diagnosis must be followed before replacing any ignition coils.

PRODUCTION SOLUTION

Improved ignition coil since 2008 model year.

SERVICE

OBTAIN INFORMATION FROM THE CUSTOMER

To repair the vehicle correctly, please try to obtain as much information as possible from the customer about the symptoms of the condition and when it occurred.

  • In what situation (turning, etc.) does the condition occur?
  • Under what environmental conditions (road conditions, weather, temperature, start conditions, etc.) does the condition occur?
  • What is the operating situation of the vehicle (activated electrical equipment, gear selection, etc.) when the condition occurs?
  • Can the complaint be reproduced?

WORKSHOP PROCEDURE

  1. Read out the data memory of all engine control units, and note the environmental conditions on the DTC log.
    1. If there are other entries in addition to combustion misfires, address the other entries before addressing the cylinder misfires.
    2. If DTC P0301 - P0312  (Cyl.1 Misfire Detected - Cyl.12 Misfire Detected) is accompanied by P1250  (Fuel level too low), it is likely the faults occurred due to a low fuel level and not a malfunction of the coils.
    3. Review all applicable TSBs related to cylinder misfires and ECM software improvements before diagnosing the misfire condition. For example, if data shows that a DTC was set during cold start, search ElsaWeb for TSBs related to cold start misfires.
  2. Try to duplicate customer complaint based on the environmental conditions at the time the DTC was set. The freeze data gives important indicators for the traceability of the complaint, in particular if it occurs sporadically or at cold start.
  3. Review the vehicle repair history for previous misfire or maintenance service that could be related to the current complaint.
  4. Observe the requirements of Guided Fault Finding. Perform Guided Fault Finding in full according to the proposed sequence (test plan). Do not  skip any steps.
  5. Complete Guided Fault Finding correctly and set the readiness code.

    Tip:  This is important to ensure that no subsequent faults occur due to the misfire.

  6. In the case of single cylinder misfires:
    1. Before replacing components, determine whether the complaint migrates to the other cylinders after exchanging the coils. If necessary, perform a test drive to ascertain this.
    2. If the misfire migrates to the cylinder the coil was moved to, replace only the affected coil.
  7. Verify repair under the same environmental conditions (e.g.: engine speed, engine load value, vehicle speed, coolant temperature, intake air temperature, ambient air pressure, voltage at terminal 30, etc.) as noted on the DTC log.
