INTRODUCTION
●
Before troubleshooting, verify customer complaints.
●
If a vehicle malfunction is hard to reproduce, harnesses, harness connectors or terminals may often be
malfunctioning. Hold and shake these parts by hand to make sure they are securely connected.
●
When using a circuit tester to measure voltage or resistance of each circuit, be careful not to expand con-
nector terminals.
