I/M Readiness

1. An important part of a vehicle’s OBD II system is the readiness monitors, which are indicators used to find out if all of the emissions components have been evaluated by the OBD II system. They are running periodic tests on specific systems and components to ensure that they are performing within allowable limits.
2. Currently, there are eleven OBD II readiness monitors (or I/M Monitors) defined by the U.S. Environmental Protection Agency (EPA). Not all monitors are supported in every vehicle, and the exact number of monitors in any vehicle depends on the motor vehicle manufacturer’s emissions control strategy.

Continuous Monitors

1. Some of the vehicle components or systems are continuously tested by the vehicle’s OBD II system, while others are tested only under specific vehicle operating conditions. The continuously monitored components listed below are always ready:
   • Misfire
   • Fuel System
   • Comprehensive Components (CCM)
2. Once the vehicle is running, the OBD II system is continuously checking the above components, monitoring key engine sensors, watching for engine misfires, and monitoring fuel demands.

Non-Continuous Monitors

1. Unlike the continuous monitors, many emissions and engine system components require the vehicle to be operated under specific conditions before the monitor is ready. These monitors are termed noncontinuous monitors and are listed below:
   • EGR System
   • O2 Sensor
   • Catalyst
   • Evaporative System
   • O2 Sensor Heater
   • Secondary Air Injection
   • Heated Catalyst
   • A/C system
2. I/M refers to inspection and maintenance that is legislated by the Government to meet federal clean-air standards. I/M Readiness indicates whether or not the various emissions-related systems on the vehicle are operating properly and are ready for inspection and maintenance testing.
3. The purpose of the I/M readiness monitor status is to indicate which of the vehicle’s Monitors have run and completed their diagnosis and testing, and which ones have not yet run and completed testing and diagnosis of their designated sections of the vehicle’s emissions system.
4. The I/M readiness monitor status function can also be used after repair of a fault has been performed to confirm that the repair has been performed correctly, and or to check for monitor run status.

Data Stream

1. Retrieves and displays live data and parameters from the vehicle’s ECU.

View Freeze Frame

1. When an emission-related fault occurs, certain vehicle conditions are recorded by the onboard computer. This information is referred to as freeze frame data. 2. Freeze Data is a snapshot of the operating conditions at the time of an emission-related fault.

NOTE: If DTCs were erased, freeze data may not be stored in the vehicle memory, depending on the vehicle.

O2 Sensor Test

1. The results of the O2 sensor test are not live values but instead the results of the ECU’s last O2 sensor test. For live O2 sensor readings, refer to any of the live sensor screens, such as the graph screen.
2. Not all test values apply to all vehicles. The list generated will vary depending on the vehicle. Not all vehicles support the oxygen sensor screen.

On-Board Monitor Test

1. This function can be utilized to read the results of onboard diagnostic monitoring tests for specific components/systems.

EVAP System Test

1. The EVAP test function lets you initiate a leak test for the vehicle’s EVAP system. The tool does not perform the leak test, but signals to the vehicle’s onboard computer to initiate the test. Before using the system test function, refer to the vehicle’s service repair manual to determine the procedures necessary to stop the test.

Vehicle Info

1. This option displays the vehicle information, such as VIN (Vehicle Identification Number), CID (Calibration ID), and CVN (Calibration Verification Number). Compatible with ET2900 Bluetooth Battery Clamps (Optional Accessory, Sold Separately). CMMT98374 elite code reader can pair with ET2900 (sold separately) after upgrading the software. You can operate all functions of ET2900 from the CMMT98374elite code reader.

History
Once a vehicle diagnosis is performed, the tool will record every detail of the diagnostic session. The history function provides direct access to the previously tested vehicles, and users can resume from the last operation without needing to start from scratch. Select history on the diagnosis main menu screen. All diagnostic records will be listed on the screen in date sequence.

1. Select the vehicle model to view the details of the last diagnostic report.
2. To delete certain diagnostic history, select it and then select delete. To delete all historical records, select “select all” and then select delete.
3. Select quick access to directly navigate to the function selection page of the last diagnostic operation. Choose the desired option to proceed.

Reset (Special Functions)

1. Select reset. All available reset software will be listed on the screen.
2. Select the desired reset software and follow the on-screen instructions to proceed. There are two methods to perform the reset procedures:
   1. Manual reset
   2. Auto

Reset

1. Auto reset follows the principle of sending a command from the tool to the vehicle’s ECU to reset.
2. For manual reset, users just follow the onscreen instructions to select appropriate execution options, enter the correct data or values, and perform necessary actions. The system will guide you through the complete performance for various service operations.
