What is Readiness Inc OBD2 and How to Check It?

Readiness Inc Obd2 refers to the status of your vehicle’s emission control systems, indicating whether they have completed self-tests. This article, brought to you by OBD2-SCANNER.EDU.VN, will explore how to interpret and use this information to ensure your vehicle is running efficiently and meets emission standards. You’ll also learn about OBD2 scanner tools, diagnostic procedures, and automotive repair services.

1. Understanding Readiness Monitors in OBD2 Systems

Readiness monitors are self-diagnostic routines that assess the emission control systems of your car. These monitors, sometimes called Emission Monitors, observe the performance of your vehicle’s emission-related components. They provide valuable insights into your car’s overall health. The Environmental Protection Agency (EPA) emphasizes the importance of these monitors in maintaining air quality.

• Purpose: To test and monitor the performance of the car’s emission control systems.
• Function: Self-test routines that provide insight into the car’s self-diagnostics.
• Importance: Critical for ensuring the vehicle meets emission standards and runs efficiently.

2. Types of Readiness Monitors: Continuous and Non-Continuous

There are two main types of readiness monitors: continuous and non-continuous. Continuous monitors are constantly tested while the engine is running, whereas non-continuous monitors require specific conditions to be met before a test can be completed. The Society of Automotive Engineers (SAE) standard J1979 previously categorized each monitor, but newer standards provide more flexibility.

2.1. Continuous Monitors

Continuous monitors are designed to evaluate systems in real-time as the vehicle operates. Because these tests are continuous, any problems can be detected quickly.

• Misfire Monitor: Detects engine misfires that could damage the catalytic converter.
• Fuel System Monitor: Assesses the fuel delivery system’s performance.
• Comprehensive Component Monitor: Checks various electrical components for proper function.

2.2. Non-Continuous Monitors

Non-continuous monitors need specific conditions to be met before the test can be run. These conditions can vary, including defined drive cycle routines or cool-down and warm-up periods.

2.2.1. Spark Ignition Vehicles (Gasoline)

For gasoline engines, non-continuous monitors include:

• Catalyst (CAT) Monitor: Evaluates the efficiency of the catalytic converter.
• Heated Catalyst Monitor: Checks the performance of the heated catalytic converter.
• Evaporative (EVAP) System Monitor: Tests for fuel vapor leaks in the evaporative emission control system.
• Secondary Air System Monitor: Monitors the secondary air injection system.
• Oxygen (O2) Sensor Monitor: Evaluates the performance of the oxygen sensors.
• Oxygen Sensor Heater Monitor: Checks the functionality of the oxygen sensor heaters.
• EGR (Exhaust Gas Recirculation) and/or VVT System Monitor: Monitors the exhaust gas recirculation system and variable valve timing system.

2.2.2. Compression Ignition Vehicles (Diesel)

For diesel engines, non-continuous monitors include:

• NMHC Catalyst Monitor: Evaluates the efficiency of the Non-Methane Hydrocarbon catalyst.
• NOx/SCR Aftertreatment Monitor: Checks the performance of the NOx Selective Catalytic Reduction system.
• Boost Pressure Monitor: Monitors the boost pressure generated by the turbocharger.
• Exhaust Gas Sensor Monitor: Evaluates the performance of the exhaust gas sensors.
• PM Filter Monitor: Checks the functionality of the Particulate Matter filter.
• EGR and/or VVT System Monitor: Monitors the exhaust gas recirculation system and variable valve timing system.

3. Monitoring Cycles: Understanding Current and Reset Status

Modern OBD2 systems report emission monitor status for both the current driving cycle and the status since the diagnostic trouble codes were last cleared. This dual reporting helps in diagnosing intermittent issues. The current drive cycle status starts fresh with each new cycle, while the reset status shows the long-term performance after a reset. Older cars might not support the current driving cycle feature, in which case OBD Auto Doctor marks it as NA (Not Available).

• Current Drive Cycle: Status is set to incomplete at the start of each new driving cycle.
• Status Since Reset: Reflects the status after the diagnostic trouble codes were cleared.

4. Interpreting Monitor Status: Complete, Incomplete, and Disabled

Each readiness monitor provides a status indicating whether the test has been completed successfully. Understanding these statuses is crucial for diagnosing issues and preparing for vehicle inspections.

4.1. Complete or Ready

A “Complete” or “Ready” status indicates that the OBD-II system has successfully checked the emissions control system. OBD Auto Doctor indicates this status with a green check mark.

4.2. Incomplete or Not Ready

An “Incomplete” or “Not Ready” status means that the OBD2 system has not been able to run the routine or it has failed. OBD Auto Doctor indicates this status with a red exclamation mark.

4.3. Disabled

A “Disabled” status means that the test has been disabled for the rest of the monitoring cycle. This can occur when environmental conditions prevent the monitor from running.

5. Reasons for Incomplete Monitors and How to Address Them

An incomplete monitor status can result from several factors, including recent DTC clearing, power failures, or the start of a new monitoring cycle. Here’s how to address them.

5.1. Clearing Diagnostic Trouble Codes (DTCs)

Clearing DTCs and resetting the Check Engine Light will also reset the monitor statuses. This typically occurs after a vehicle repair, requiring the monitors to be re-run to achieve a “Complete” status.

5.2. Power Failure

Statuses are also reset in case of power failure, often due to battery disconnection. If you need to disconnect the battery, be prepared to reset the monitors afterward.

5.3. Start of a New Monitoring Cycle

For the current monitoring cycle, the status is set to incomplete upon starting the engine. It is normal for these monitors to be incomplete when starting the engine.

5.4. Inspection Requirements

Depending on your location, your vehicle may not pass inspection unless the required monitors are complete. The US Environmental Protection Agency guidelines allow up to two monitors to be not ready for model year 1996 through 2000 vehicles, and only one monitor for 2001 and newer models.

6. Step-by-Step Guide to Getting Monitors Complete or “Ready”

The best way to get the monitors ready is to drive the car under specific conditions. Here is a step-by-step guide to help you achieve this.

6.1. Initial Checks

1. Ensure that the Malfunction Indicator Light (MIL) is not on. Active stored or pending DTCs may prevent monitors from running.
2. Ensure you have enough fuel. Some monitors, like the EVAP monitor, require the fuel level to be between 35% and 85%.

6.2. Performing an OBD Drive Cycle

The OBD drive cycle allows your car to run on-board diagnostics, enabling the readiness monitors to operate. The specific drive cycle can vary depending on the car model and manufacturer.

6.2.1. General Drive Cycle Steps

1. Cold Start: Ensure the coolant temperature is below 50°C (122°F) and the coolant and air temperatures are within 11 degrees of each other. Let the car sit overnight to achieve this condition.
2. Idling: Start the engine and idle in drive for two and a half minutes with the A/C and rear defroster on, if equipped.
3. Acceleration: Turn off the A/C and rear defroster, then accelerate to 90 km/h (55 mph) under moderate, constant acceleration. Hold steady for three minutes.
4. Deceleration: Slow down to 30 km/h (20 mph) without braking. Do not depress the clutch if you have a manual transmission.
5. High-Speed Cruise: Accelerate back to 90-100 km/h (55-60 mph) at 3/4 throttle and hold steady for five minutes.
6. Final Deceleration: Slow down to a stop without braking.

6.2.2. Tips for a Successful Drive Cycle

• Perform the drive cycle in a restricted area due to the varying speed requirements.
• Consult your vehicle’s owner’s manual for the manufacturer’s recommended drive cycle.
• About one week of combined city and highway driving is usually enough to allow the monitors to reach complete status.
