3. OBD-II Introduction

3.1 OBD II/EOBD II System

The On-Board Diagnostics (OBD II) system monitors emission control systems and key engine components. When a problem is detected, the OBD II system turns on a Malfunction Indicator Light (MIL) on the vehicle instrument panel, often displaying "Check Engine" or "Service Engine Soon." The system stores important information about the malfunction, including:

1. Whether the Malfunction Indicator Light (MIL) is commanded 'on' or 'off'.
2. Which, if any, Diagnostic Trouble Codes (DTCs) are stored.
3. Readiness Monitor status.

3.2 Data Link Connector (DLC)

The DLC is the standardized 16-cavity connector used to interface diagnostic scan tools with the vehicle's on-board computer. It is typically located within 12 inches of the center of the instrument panel, under or around the driver's side. If not immediately visible, a label usually indicates its location. For some vehicles, it may be behind the ashtray.

5.1 Read DTCs (Diagnostic Trouble Codes)

DTCs are codes stored by the on-board computer diagnostic system in response to a vehicle problem. They guide you to the fault area. There are three types of DTCs:

• Stored DTCs: A fault condition has occurred that meets criteria to activate the MIL.
• Pending DTCs: A fault condition is identified during a Drive Cycle but does not yet meet criteria to activate the MIL.
• Permanent DTCs: Stored DTCs that can only be cleared by the OBDII system after repairs and a set number of Driving Cycles.

DTCs consist of a five-digit alphanumeric code:

• First character (Letter): Identifies the control system (P=Powertrain, B=Body, C=Chassis, U=Network).
• Second character (Number): Indicates code type (0=Generic/SAE, 1=Manufacturer Specific).
• Third character (Number): Identifies the sub-system (e.g., 1=Fuel and Air Metering, 3=Ignition System).
• Fourth & Fifth characters (Numbers): Identify the specific malfunction section.

To read DTCs:

1. Use UP/DOWN scroll buttons to select 'Read DTC' from the Diagnostic Menu and press OK.
2. Use UP/DOWN scroll buttons to select 'Stored Codes', 'Pending Codes', or 'Permanent Codes' from the Read Codes menu and press OK.
3. View DTCs and their definitions on screen. If multiple DTCs, use UP/DOWN to scroll.
4. If manufacturer-specific codes are found, select the vehicle manufacturer to view definitions.

5.2 Clear DTCs

CAUTION: Erasing DTCs also deletes "Freeze Frame" data and resets I/M Readiness Monitors to "Not Ready." Do not erase codes before a complete system check by a technician.

To clear DTCs:

1. Use UP/DOWN scroll buttons to select 'Clear DTCs' from the Diagnostics Menu and press OK.
2. Choose whether to erase codes.
