Preparation for Testing VEHICLE SERVICE MANUALS VEHICLE SERVICE MANUALS Always refer to the manufacturer’s service manual for your vehicle before performing any test or repair procedures. Contact your local car dealership, auto parts store or bookstore for availability of these manuals.
General Code Retrieval Procedures OBD1 SYSTEMS / OBD2 SYSTEMS Procedures for Retrieving Diagnostic Trouble Codes from OBD1 systems are vehicle manufacturer specific. Each manufacturer uses their own procedure. Procedures for retrieving Diagnostic Trouble Codes from OBD2 systems are generic, and apply to all vehicles equipped with OBD2 systems. From the following list, select the procedure that applies to your vehicle’s OBD system, and proceed to appropriate section for detailed code retrieval procedures.
OBD2 Systems VEHICLES COVERED VEHICLES COVERED The CanOBD2&1 Scan Tool is designed to work on all OBD 2 compliant vehicles. All 1996 and newer vehicles (cars and light trucks) sold in the United States are OBD 2 compliant. Federal law requires that all 1996 and newer cars and light trucks sold in the United States must be OBD 2 compliant; this includes all Domestic, Asian and European vehicles. Some 1994 and 1995 vehicles are OBD 2 compliant.
OBD2 Systems DIAGNOSTIC TROUBLE CODES (DTCs) On some Asian and European vehicles the DLC is located behind the “ashtray” (the ashtray must be removed to access it) or on the far left corner of the dash. If the DLC cannot be located, consult the vehicle’s service manual for the location. DIAGNOSTIC TROUBLE CODES (DTCs) Diagnostic Trouble Codes (DTCs) are meant to guide you to the proper service procedure in the vehicle’s service manual.
OBD2 Systems DIAGNOSTIC TROUBLE CODES (DTCs) OBD 2 DTC EXAMPLE P0201 - Injector Circuit Malfunction, Cylinder 1 B C P U - Body Chassis Powertrain Network 0 1 2 3 - Generic Manufacturer Specific Generic Includes both Generic and Manufacturer Specific Codes P0201 Identifies the system where the problem is located: 1 - Fuel and Air Metering 2 - Fuel and Air Metering (injector circuit malfunction only) 3 - Ignition System or Misfire 4 - Auxiliary Emission Control System 5 - Vehicle Speed Control and Idl
OBD2 Systems CODE RETRIEVAL PROCEDURE CODE RETRIEVAL PROCEDURE Retrieving and using Diagnostic Trouble Codes (DTCs) for troubleshooting vehicle operation is only one part of an overall diagnostic strategy. Never replace a part based only on the DTC definition. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the location of the problem. This information is found in the vehicle's service manual.
OBD2 Systems CODE RETRIEVAL PROCEDURE ■ If the unit does not power on automatically when connected to the vehicle’s DLC connector, it usually indicates there is no power present at the vehicle’s DLC connector. Check your fuse panel and replace any burned-out fuses. ■ If replacing the fuse(s) does not correct the problem, consult your vehicle’s repair manual to identify the proper computer (PCM) fuse/ circuit, and perform any necessary repairs before proceeding. 5. Turn the ignition on.
OBD2 Systems CODE RETRIEVAL PROCEDURE ■ The CanOBD2&1 Scan Tool will automatically re-link to the vehicle’s computer every 30 seconds to refresh the data being retrieved. When data is being refreshed, the message “One moment Auto – link in progress” is shown on the display. This action repeats as long as the CanOBD2&1 Scan Tool is communicating with the vehicle’s computer. ■ The CanOBD2&1 Scan Tool will display a code only if codes are present in the vehicle’s computer memory.
OBD2 Systems CODE RETRIEVAL PROCEDURE In the case of long code definitions, or when viewing Freeze Frame data, a small arrow is shown in the upper/lower right-hand corner of the code display area to indicate the presence of additional information. Use the and buttons, as necessary, to view the additional information. 9. Read and interpret Diagnostic Trouble Codes/system condition using the display and the green, yellow and red LEDs.
OBD2 Systems CODE RETRIEVAL PROCEDURE ■ Red LED – Indicates there is a problem with one or more of the vehicle’s systems. The red LED is also used to indicate that DTC(s) are present (displayed on the CanOBD2&1 Scan Tool’s screen). In this case, the Malfunction Indicator (Check Engine) lamp on the vehicle’s instrument panel will be illuminated. ■ DTC’s that start with “P0”, “P2” and some “P3” are considered Generic (Universal). All Generic DTC definitions are the same on all OBD2 equipped vehicles.
OBD2 Systems CODE RETRIEVAL PROCEDURE 10. If more than one code was retrieved press the DTC SCROLL button, as necessary, to display additional codes one at a time. ■ Each time the DTC SCROLL button is pressed and released, the CanOBD2&1 Scan Tool will scroll and display the next DTC in sequence until all DTCs in its memory have displayed. ■ Freeze Frame Data (if available) will display after DTC #1.
OBD2 Systems ERASING DIAGNOSTIC TROUBLE CODES (DTCs) ■ To prolong battery life, the CanOBD2&1 Scan Tool automatically shuts “Off” approximately three minutes after it is disconnected from the vehicle. The DTCs retrieved, Monitor Status and Freeze Frame data (if any) will remain in the CanOBD2&1 Scan Tool’s memory, and may be viewed at any time by turning the unit “On”.
OBD2 Systems I/M READINESS TESTING 3. Press and release the ERASE button. A confirmation message shows on the LCD display. - If you are sure you want to proceed press the ERASE button again to erase DTCs from the vehicle’s computer. - If you do not want to continue with the erase process, press the POWER/LINK button to exit the erase mode. 4. If you chose to erase DTCs, a progress screen displays while the erase function is in progress.
OBD2 Systems I/M READINESS TESTING Emissions tests vary depending on the geographic or regional area in which the vehicle is registered. If the vehicle is registered in a highly urbanized area, the I/M 240 is probably the type of test required. If the vehicle is registered in a rural area, the stricter “dynamometer type” test may not be required.
OBD2 Systems I/M READINESS TESTING ■ If a Monitor was able to meet all the conditions required to enable it to perform the self-diagnosis and testing of its assigned engine system, it means the monitor "HAS RUN.” ■ If a Monitor has not yet met all the conditions required for it to perform the self-diagnosis and testing of its assigned engine system; it means the Monitor "HAS NOT RUN.” The Monitor Run/Not Run status does not show whether or not a problem exists in a system.
OBD2 Systems I/M READINESS TESTING Monitors with a "Has Run" status indicate that all the required conditions they needed to perform diagnosis and testing of their assigned engine area (system) have been met, and all diagnostic testing has completed successfully. Monitors with a "Has Not Run" status have not yet met the conditions they need to perform diagnosis and testing of their assigned engine area (system), and have not been able to perform diagnostic testing on that system.
OBD2 Systems I/M READINESS TESTING - Some areas require that all Monitors indicate a "Has Run" status before they allow an Emissions Test (Smog Check) to be performed. Other areas only require that some, but not all, Monitors have run their self-diagnostic testing before an Emissions Test (Smog Check) may be performed. From the code retrieval procedure, determine the status of each Monitor (a solid Monitor icon shows Monitor "Has Run" status, a flashing Monitor icon indicates "Has Not Run" status).
OBD2 Systems I/M READINESS TESTING ■ See page 30 for procedures to erase DTCs from the vehicle's onboard computer. ■ Write the codes down on a piece of paper for reference before erasing. 3. After the erase procedure is performed, most of the Monitor icons on the CanOBD2&1 Scan Tool’s display will be flashing.
OBD2 Live Data Mode VIEWING LIVE DATA The CanOBD2&1 Scan Tool is a special diagnostic tool that communicates with the vehicle's computer. The CanOBD2&1 Scan Tool lets you view and/or "capture" (record) "real-time" Live Data. This information includes values (volts, rpm, temperature, speed etc.) and system status information (open loop, closed loop, fuel system status, etc.) generated by the various vehicle sensors, switches and actuators.
OBD2 Live Data Mode CUSTOMIZING LIVE DATA (PIDs) ■ If communication with the vehicle is lost while viewing Live Data, a Communication Lost" message shows on the CanOBD2&1 Scan Tool's display. 5.
