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 ?
YES
1) Repair as necessary and go to "Verification Vehicle Repair" procedure
NO
1) Go to "Power Supply Circuit Inspection" procedure

Power Supply Circuit Inspection

Check sensing terminal of alternator
1. IGN : OFF
2. Disconnect alternator connector
3. IGN : ON
4. Measure voltage value between terminal "C01-1" of alternator and chassis ground.
A. Specification : 11.5 - 13.5V




5. Is the measured voltage within specifications ?
YES
1) Go to "Check lamp terminal of alternator" procedure.
NO
1) Check Powertrain fuse in FAM (7.5 A) and check for open in pertinent circuit harness and then go to "Verification of Vehicle Repair" procedure.
Check lamp terminal of alternator
1. IGN : OFF
2. Disconnect alternator connector
3. IGN : ON
4. Measure voltage value between terminal "C01-2" of alternator and chassis ground.
A. Specification : 10.5 - 12.0V




5. Is the measured voltage within specifications ?
YES
1) Go to "Check descent of voltage" procedure.
NO
1) Check IG1 fuse in IPM (7.5A), alternator registor and check for open in pertinent circuit harness and then go to "Verification of Vehicle Repair" procedure.
Check descent of voltage
1. Ignition "ON" & Engine "ON"
2. Measure voltage value between terminal "C02" of alternator and "+" terminal of battery.
A. Specification : 0.2V or less




3. Is the measured voltage within specifications ?
YES
1) Go to "Component Inspection" procedure.
NO
1) Check for corrosion and deterioration.of alternator cable. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
