Inspection For PCM Connector: Notes

1. If it is possible to check the current DTC by reproducing the fault, perform the basic inspection below before the detailed inspection.

   Information 

   Since the electronic control device is composed of numerous wires and connectors, many causes of failure are caused by poor contact as follows:

   These failures cause failures of various phenomena including DTC and also damage parts.

   List of Inspection	How to Inspect	Part to Inspect
   1. Poor connection of connector	Check whether connector is connected temporarily or incompletely	Alternator PCM ECU1 fuse PCB-C middle connector
   2. Pushed and deformed terminal	Check the faulty terminal pin, such as pushing, bending, warping.
   3. Terminal corrosion/contamination	Corrosion caused by moisture ingress Check poor contact due to inflow of contaminants, such as oil

OK 

Go to "Inspection For Run "Vehicle S/W Management" - Read VIN"  procedure.

NG 

If it is simply caused by moisture inflow without corrosion, locate and repair the cause.

If the pin contact point of connector is loosened, repair the part.

If the unit has corrosion due to the moisture inflow, replace corroded unit or wiring assembly.

Go to "Final DTC Checking"  procedure.

Information 

The following cases are caused by the inflow of moisture in the connector.
