Vehicle Coverage
The Autm or AT 018 OBD II /EOBD Code Reader is specially designed to work with all OBD II-compliant vehicles, including those equipped with the next-generation protocol–Control Area Network (CAN). It is required by EPA that all 1996 and newer vehicles (cars and light trucks) sold in the United States must be OBD II compliant and this includes all Domestic, Asian and European vehicles.
A small number of 1994 and 1995 model-year gasoline vehicles are OBD II compliant. To verify a 1994 or 1995 vehicle is OBD II compliant, check the Vehicle Emissions Control Information (VECI) Label which is located under the hood or by the radiator of most vehicles. If the vehicle is OBD II compliant, the label will be designated “OBD II Certified”. Additionally, Government regulations mandate that all OBD II-compliant vehicles must have a “common” sixteen-pin Data Link Connector (DLC).
For your vehicle to be OBD II compliant it must have a 16-pin DLC (Data Link Connector) under the dash and the Vehicle Emission Control Information Label must state that the vehicle is OBD II compliant.
OBD II Diagnostics
When more than one vehicle control module is detected by the scan tool, you will be prompted to select the module where the data may be retrieved. The most often to be selected are the Powertrain Control Module [PCM] and Transmission Control Module [TCM].
CAUTION: Don’t connect or disconnect any test equipment with the ignition on or the engine running.
- Turn the ignition off.
- Locate the vehicle’s 16-pin Data Link Connector (DLC).
- Plug into the OBD II cable to the vehicle’s DLC.
- Turn the ignition on. Engine can be off or running.
- Press the RETURN/OK button to enter the Diagnostic Menu.
Erasing Codes
CAUTION: Erasing the Diagnostic Trouble Codes may allow the code reader to delete not only the codes from the vehicle’s onboard computer but also “Freeze Frame” data and manufacturer-enhanced data. Further, the I/M Readiness Monitor Status for all vehicle monitors is reset to Not Ready Not Complete status. Do not erase the codes before the system has been checked completely by a technician.
This function is performed with a key on the engine of (KOEO). Do not start the engine.
Retrieving I/M Readiness Status
The I/M Readiness function is used to check the operations of the Emission System on OBD2-compliant vehicles. It is an excellent function to use prior to having a vehicle inspected for compliance with a state emissions program.
Some latest vehicle models may support two types of I/M Readiness tests:
- Since DTCs Cleared the status of the monitors the DTCs are erased.
- This Drive cycle indicates the status of monitors since the beginning of the current drive cycle.
