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.
