Basic Inspection

When the malfunction is not confirmed in the DTC check, troubleshooting should be carried out in all possible circuits considered as causes of the problem. In many cases, by carrying out the basic engine check shown in the following flow chart, the location causing the problem can be found quickly and efficiently. Therefore, using this check is essential in the engine troubleshooting.

1. CHECK BATTERY VOLTAGE
