4.5 Read I/M Readiness Status Data 

I/M Readiness option allows to view a snapshot of the operations for the emission system on 

OBDII/EOBD vehicles.   
I/M Readiness is a useful function used to check if all monitors are OK or N/A. The vehicle’s

computer performs tests on the emission system during normal driving conditions. After a specific 

amount of drive time (each monitor has specific driving conditions and time required), the 

computer’s monitors decide if the vehicles emission system is working correctly.   
When the monitor’s status is: 

OK - vehicle was driven enough to complete the monitor.

INC (Incomplete) - vehicle was not driven enough to complete the monitor.

N/A (Not Applicable) - vehicle does not support that monitor.

There are two types of I/M Readiness tests: 

Since DTCs Cleared - shows status of the monitors since the DTCs were last cleared.

This Drive Cycle - shows status of monitors since the start of the current drive cycle.

Below is a list of abbreviations and names of OBD II monitors supported by the code reader.

There are two ways to retrieve I/M Readiness Status data: 

● One-click I/M readiness key

● Typical way: select I/M Readiness from Diagnostic Menu

NOTE

 

To review I/M Readiness status, make sure that the ignition key is switched to ON with the

engine off. 

Not all monitors are supported by all vehicles.

To retrieve I/M Readiness Status data by one-click I/M readiness key: 

1. Press the 

One-Click I/M Readiness Key 

on the keypad and the following screen displays.

Figure 4-30 Sample Diagnostic Menu Screen 

2. Colored LED and build-in beeper provide both visual and audible reminders for emission

check and DTCs. Below is the intepretation of the LED and build-in beeper.
When the LED is :

● 

Green - Indicates that engine systems are “OK” and working properply (the number of

Monitors equipped with the vehicle which have run and performed their self-diagnostic

testing is in the allowed range. MIL is off. ).No stored and pending DTCs exist. The

vehicle is ready for an Emissions Test.

● 

Yellow - The tool finds a possible problem. It indicates the following two conditions:

    (1) Pending DTCs exist. Please check the I/M Readiness test result screen and use the 

Read Codes function to view detailed codes information. 

  (2) Some of the vehicle’s emission monitors have not working properly. If the I/M 

Readiness screen shows no DTC (including pending DTC), but the Yellow LED is 

still illuminated, it indicate a “Monitor Has Not Run” status.   

● 

Red - Indicates some problems exist with one or more of the vehicle’s system, and the

vehicle is not ready for an Emissions Test. As well there are DTCs found. The MIL lamp

on  the  vehicle’s  instrument  panel  will  light  steady.  The  problem  that  is  causing  the

illumination of Red LED should be fixed before an Emissions Test or driving the vehicle

further.

The built-in beeper works with the colored LED simultaneous, as an assistance to reflect the I/M 

Readiness test results: 

Green - two long beeps.

Yellow - short, long, short beeps.

Red - four short beeps.

NOTE

 

    The built-in beeper which makes different tones corresponding to different LED indicators is 

invaluable when the test is performed while driving or in bright areas where LED illumination 

may not be visible. 

To retrieve I/M Readiness Status data by typical way: 

1. Scroll with 

UP/DOWN

 key to highlight 

I/M Readiness

 from Diagnostic Menu and press the

ENTER

 key. If vehicle supports both types of monitors, a screen for monitor type selection

displays. Select a monitor type and press the 

ENTER

 key.
