How to Perform Trouble Diagnosis for Quick and Accurate RepairNES000K7
INTRODUCTION
Before troubleshooting, verify customer complaints.
If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
When using a circuit tester to measure voltage or resistance of each circuit, be careful not to damage or
deform connector terminals.
