HLA, Switchable HLA Troubleshooting

WARNING: This page is about a different variant/trim than selected.

Item	Occurrence	Possible cause	Action
1	After replacing oil, sound occurs when starting engine	Oil shortage in oil passage	Maintain the engine speed between 2, 000 to 3, 000 rpm for approx. 2 s and 10 min *, and verify that the sound disappears. If the sound disappears, the HLA and switchable HLA are normal. If the sound does not disappear, go to item 5.
2	Sound occurs at instant when engine is started on vehicle left for 1 day	Oil shortage in oil passage
3	Starter cranked for 3 s or more and sound occurs directly after engine is started	Oil shortage of HLA and switchable HLA
4	Sound occurs directly after engine is started with newly replaced HLA and switchable HLA	Oil shortage of HLA and switchable HLA
5	Sound occurs continuously for 10 min or more	Insufficient oil pressure	Inspect the oil pressure. (See OIL PRESSURE INSPECTION ). If less than the specification, inspect each part of the engine.
5	Sound occurs continuously for 10 min or more	Malfunction of HLA and switchable HLA	Inspect the HLA and switchable HLA. (See HLA, Switchable HLA Inspection ).
6	Sound occurs during idling after high-speed driving	Incorrect engine oil level	Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION ).
6	Sound occurs during idling after high-speed driving	Engine oil deterioration	Replace the engine oil. (See ENGINE OIL REPLACEMENT ).

*: Period of time engine oil flows to the HLA and switchable HLA, this value includes tolerance caused by the ambient temperature and the oil used.
