HINT

1. In contrast to normal malfunction diagnosis for components, circuits and systems, DTCs P1603 and P1605 are used to determine the malfunctioning area from the problem symptoms and freeze frame data when the user mentions problems such as engine stall. As these DTCs can be stored as a result of certain user actions, even if these DTCs are output, if the customer makes no mention of problems, clear these DTCs without performing any troubleshooting and return the vehicle to the customer.
2. If any other DTCs are output, perform troubleshooting for those DTCs first.
3. Use any information from the customer problem analysis about the condition of the vehicle at the time when the problem occurred (how the engine stopped, conditions when the engine was restarted, etc.) as a reference. Symptom Suspected Area Engine vibration occurs and engine stops Air fuel ratio abnormal Engine stops with no engine vibration Ignition system, injection stoppage, high load from external parts Engine can be started with accelerator pedal depressed Insufficient air volume Rough idling after engine started Air fuel ratio abnormal, abnormal combustion
4. Read freeze frame data using the Techstream. Freeze frame data records engine conditions when a malfunction occurs. This information can be useful when troubleshooting.
5. When confirming the freeze frame data, be sure to check all 5 sets of freeze frame data. Refer to «FREEZE FRAME DATA [12/2013 - ]»(ref-636036-S02226335012014070700000)
6. When DTC P1603 (Engine Stall History) is stored, DTC P1605 (Rough Idling) is also stored. When confirming freeze frame data, check DTC P1605. The ECM stores DTC P1605 first. Therefore, 5 sets of freeze frame data can be confirmed through DTC P1605, enabling the technician to obtain more information.
7. When confirming freeze frame data, if there are multiple items related to the cause of the malfunction, perform troubleshooting for all related items.
8. Try to operate the vehicle under the conditions recorded in the freeze frame data which were present when the malfunction occurred. Confirm the data at this time and the data when the engine is idling (engine warmed up, no load, and shift lever in D or N) and compare this data with the freeze frame data.
9. Inspections take into account the fact that the malfunction may not have recurred and place emphasis on checking the vehicle conditions present at the time when the malfunction occurred.
10. When performing inspections, jiggle the relevant wire harnesses and connectors in an attempt to reproduce malfunctions that do not always occur.

Inspection flow

Using freeze frame data, narrow down the parts to be inspected according to the vehicle conditions at the time when the malfunction occurred.

P1603

Scheme 443

1

1. If the engine stalled when the intake air volume was low (during idling or deceleration), there may be a decrease in torque due to an incorrect air fuel ratio, etc.
2. If the engine stalled when the intake air volume was high (during driving or acceleration), there may be a major malfunction such as continuous misfire due to ignition stoppage, fuel injection stoppage, etc. and the torque drops to zero.

2

1. If the engine speed decreased slowly, there may have been a decrease in torque due to an air fuel ratio that was incorrect (by approximately 20 to 30%), etc.
2. If the engine speed decreased rapidly, there may have been a malfunction such as when the engine misfires almost continuously due to ignition stoppage, fuel injection stoppage, etc., or when the external load increases due to an external part malfunctioning.

3

1. If the air fuel ratio is abnormal, there may have been an intake air leak, sensor malfunction, or fuel supply problem.
2. If the vehicle was normal, the air volume may have been insufficient or the ignition timing may have been incorrect.

HINT

1. In contrast to normal malfunction diagnosis for components, circuits and systems, DTC P1604 is used to determine the malfunctioning area from the problem symptoms and freeze frame data when the user mentions problems such as starting difficulty. As this DTC can be stored as a result of certain user actions, even if the DTC is output, if the customer makes no mention of problems, clear the DTC without performing any troubleshooting and return the vehicle to the customer.
2. If any other DTCs are output, perform troubleshooting for those DTCs first.
3. When the Data List item "Immobilizer Fuel Cut" is ON, the engine cannot be started.
4. Read freeze frame data using the Techstream. Freeze frame data records engine conditions when a malfunction occurs. This information can be useful when troubleshooting.
5. When confirming the freeze frame data, be sure to check all 5 sets of freeze frame data. Refer to «FREEZE FRAME DATA [12/2013 - ]»(ref-636036-S02226335012014070700000)
6. When confirming the freeze frame data, if there are multiple items related to the cause of the malfunction, perform troubleshooting for all related items.
7. Try to start the vehicle under the conditions recorded in the freeze frame data which were present when the malfunction occurred. Confirm the data at this time and compare it with the freeze frame data.
8. If the malfunction does not recur, carefully check the vehicle conditions from when the malfunction occurred using freeze frame data.
9. When performing inspections, jiggle the relevant wire harnesses and connectors in an attempt to reproduce malfunctions that do not always occur.
10. If the same inspection or replacement procedure appears 2 times when performing an inspection procedure, it is not necessary to repeat the procedure the second time.

1. Malfunction Recurrence and Inspection Areas Freeze frame data exists, but the malfunction (starting difficulty) has not reoccurred and the malfunction conditions are unknown. The engine speed recorded in the freeze frame data is 0 RPM (the engine does not crank). HINT: One of the following problems may be present: battery depletion, excess engine friction, a starter malfunction or a crankshaft position sensor malfunction. If the battery voltage is less than 6 V during cranking, there is a high probability that engine friction is abnormal. If the battery voltage drops to 5 V or less when starting the engine, the battery may be malfunctioning. If the battery voltage fluctuates while cranking the engine, it can be concluded that cranking is being performed. When the engine speed is 0 RPM, the crankshaft position sensor and/or an ECM may be malfunctioning. All engine speeds recorded in the freeze frame data are between 60 and 250 RPM (the engine cranks but there is no combustion). HINT: If the engine speed is between 60 and 250 RPM (no initial combustion), there may be a wiring problem or a complete failure of an ignition or fuel system part. Due to an engine coolant temperature sensor malfunction, the fuel injection volume is extremely high or low and the engine may not be able to be started. The engine speed recorded in the freeze frame data is 250 RPM or higher (the initial combustion and starter turnoff timing is too late). HINT: If the engine speed is 250 RPM or higher (combustion occurs but the initial combustion and starter turnoff timing is too late), the fuel injection volume is often incorrect (too low or too high) and determining the cause of the malfunction is often difficult. Due to an engine coolant temperature sensor malfunction, the fuel injection volume is extremely high or low and engine starting trouble may occur. If Long FT is incorrect, there may be a fuel supply problem due to the injectors or fuel pump being clogged, etc. If the engine cranking speed is too high, compression loss may have occurred due to carbon interfering with the valve operation. When the malfunction (starting difficulty) can be reproduced, or malfunction conditions are known, perform the following inspections ("Problem symptoms" and "Systems to inspect") Problem symptoms The engine does not crank. HINT: The starter is normal if a noise that indicates the starter pinion gear is extending is heard. The battery may be fully depleted or there may be excess engine friction. The engine cranking speed is abnormal. HINT: If the engine cranking speed is too high (for example, 300 RPM or higher with no combustion), compression loss may have occurred because carbon interfered with valve operation, etc. There is no initial combustion. HINT: If there is no initial combustion, there is probably a wiring problem or an ignition or fuel system part malfunction. The engine stalls after starter turn off. HINT: If the engine stalls after starter turn off, the air fuel ratio may be incorrect or the VVT may have a problem returning. Initial combustion and starter turn off occur late. HINT: If initial combustion and starter turn off occur late, the fuel injection volume is probably incorrect (too low or too high). HINT: Causes of fuel system malfunctions according to conditions present at the time of the malfunction. When 2 to 3 minutes have elapsed after stopping the engine: Fuel pressure loss due to the pressure regulator failing to maintain the fuel pressure. When 15 to 120 minutes have elapsed after stopping the engine: Problem with injector fuel seal. When a long time has elapsed after stopping the engine: Pressure regulator is stuck open.

FAIL-SAFE

When any of these DTCs or other DTCs relating to Electronic Throttle Control System (ETCS) malfunctions are stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator, and the throttle valve is returned to a 6° throttle valve opening angle by the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing, in accordance with the accelerator pedal opening angle, to allow the vehicle to continue running at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly.

Fail-safe mode continues until a pass condition is detected, and the ignition switch is then turned off.
