Inspection/Repair - W/Harness Inspection

Terminal and Connector Inspection

1. Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damage of component.
2. Check poor connection, beding, corrosion, contamination, deformation of connector and it terminals.
3. Is any problem found?
YES
1) Repair if necessary and go to "Verification of Vehicle Repair".
NO
1) Go to W/Harness Inspection.

Check open in power circuit
1. Ignition "ON" & engine "OFF"
2. Measure the resistance between rear defogger power circuit connector terminal at RAM side (BEC-RR-8) and rear defogger (R06-1).
A. Specification : 0 Ohms




3. Is the measured resistance within the specification?
YES
1) Go to "Check short in power circuit".
NO
1) Repair open in power circuit and go to "Verification of Vehicle Repair".
Check short in power circuit
1. Ignition "ON" & engine "OFF"
2. Disconnect rear defogger.
3. Measure the resistance between rear defogger power circuit connector terminal at RAM side (BEC-RR-8) and rear defogger (R06-1).
A. Specification : Infinity Ohms




4. Is the measured resistance within the specification?
YES
1) Go to "Component Inspection".
NO
1) Repair open in power circuit and Go to "Verification of Vehicle Repair".
