W/Harness Inspection

Engine Control
P020A Cylinder 1 Injector Timing (Injector Input Line Circuit Error) - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found ?






Control Circuit Inspection

Check voltage
1. IG "OFF" and disconnect IDB connector.
2. Connect the probe to High/Low side of the injector circuit and select the oscilloscope in the menu.
3. IG "ON".
4. Check the voltage between injector control terminal of the IDB and chassis ground.

Specification :approx. 3.5V




5. Is the measured voltage within specification ?
