SYMPTOM TROUBLESHOOTING PART DESCRIPTION

No.	TROUBLESHOOTING ITEM	DESCRIPTION
1	Blown fuses	-
2	Check engine light illuminates	Check engine light illuminates incorrectly.
3	Will not crank	Starter does not work.
4	Hard to start/long crank/erratic start/erratic crank	Starter cranks engine at normal speed but engine requires excessive cranking time before starting. Battery is operating normally.
5	Engine stalls-after start/at idle	Stalling occurs if vehicle is left idling under no load. Stalling occurs when load (electric, A/C) is applied during idling. Stalling occurs if the accelerator pedal is depressed from an idling condition when accelerating from a stop.
6	Cranks normally but will not start	Cranking occurs but no ignition.
7	Engine oil warning light illuminated/message related to engine hydraulic pressure malfunction indicated in display	Engine oil warning light illuminated. Message related to engine hydraulic pressure indicated in display.
8	Engine runs rough/rolling idle	Idle speed lower than the specification. Idling speed unstable, increases/decreases.
9	Fast idle/runs on	Engine speed continues at fast idle after warm-up. Engine runs after ignition is switched off.
10	Low idle/stalls during deceleration	Engine speed decreases when the accelerator pedal is released. Stalls during deceleration with the accelerator pedal fully released. When the accelerator pedal is fully released, vehicle stalls directly after vehicle stops.
11	Engine stalls/quits, engine runs rough, misses, buck/jerk, hesitation/stumble, surges	Stalling occurs while driving with the throttle open.
12	Lack/loss of power-acceleration/cruise	Engine speed increase delays when the accelerator pedal is fully depressed.
13	Knocking/pinging-acceleration/cruise	Abnormal combustion occurs under the condition such as the temperature in the combustion chamber is too high resulting in abnormal noise. Knocking sound occurs from the engine compartment during acceleration.
14	Poor fuel economy	Fuel economy is unsatisfactory.
15	Emission compliance	Fails emissions test.
16	High oil consumption/leakage	Oil consumption is excessive.
17	Cooling system concerns-overheating	The engine coolant temperature is abnormally high.
18	Cooling system concerns-runs cold	Engine does not reach normal operating temperature.
19	Exhaust smoke	Blue, black, or white smoke from exhaust system.
20	Fuel odor (in engine compartment)	Gasoline fuel smell or visible leakage.
21	Engine noise	Engine noise from under hood.
22	Vibration concerns (engine)	Vibration from under hood or driveline.
23	Sulfuric smell occurs	Rotten egg smell (sulphur) from exhaust.
24	Spark plug condition	Incorrect spark plug condition.
25	Fuel refill concerns	Fuel tank does not fill smoothly.
26	Fuel filling shut off concerns	Fuel does not shut off properly.
27	No cylinder deactivation	Cylinder deactivation control does not operate.
