SECTION 3
USING THE SCAN TOOL
Preparation
● DO NOT CONNECT THE SCAN TOOL TO THE VEHICLE
WHILE THE VEHICLE IS ON. Doing so could cause
damage to the scan tool or vehicle's electronic
components.
● Retrieving the DTCs is only one part of on-board
diagnostic. NEVER REPLACE THE PARTS SOLELY
BASED ON THE DIAGNOSTIC RESULTS. Always refer
to the vehicle's service manual for detailed testing
instructions.
● ALWAYS KEEP THE SAFETY PRECAUTIONS IN MIND
when working on a vehicle.
1. Turn the ignition off or to the "LOCK" position (0). (See
Figure 3.1.1)
2. Locate the vehicle's DLC
● Most of the vehicle's DLCs are located in one of the
positions labeled in Figure 3.1.2. Some DLCs have
a plastic cover that needs to be removed before
connecting and some are hidden nearby the fuse panel.
If you encounter a problem locating the DLC, please
