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	•  Engine stops unexpectedly at idle, after start, or both.
6	Cranks normally but will not start		•  Starter cranks engine at normal speed but engine will not run. •  Refer to symptom troubleshooting “NO.5 ENGINE STALLS-AFTER START/AT IDLE” if this symptom appears after engine stalls. •  Fuel is in tank. •  Battery is in normal condition.
7	Engine oil warning light illuminated/message related to engine hydraulic pressure malfunction indicated in display		•  Engine oil warning light illuminated. •  Master warning light illuminated. •  Message related to engine hydraulic pressure malfunction indicated in display.
8	Engine runs rough/rolling idle		•  Engine speed fluctuates between specified idle speed and lower speed and, engine shakes excessively. •  Idle speed is too slow and engine shakes excessively.
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 stops unexpectedly at beginning of deceleration or recovery from deceleration.
11	Engine stalls/quits	Acceleration/cruise	•  Engine stops unexpectedly at beginning of acceleration or during acceleration. •  Engine stops unexpectedly while cruising.
	Engine runs rough	Acceleration/cruise	•  Engine speed fluctuates during acceleration or cruising.
