Malfunction Indicator Lamp (MIL) Indication
(In relation to Readiness Codes) Catalytic Converter Monitor and Readiness
Code
Enable Criteria
Procedure
11-69
How to Set Readiness Codes
The vehicle has certain readiness codes that are part of
the on-board diagnostics for the emissions systems. If
the vehicle’s battery has been disconnected or gone
dead, if the DTCs have been cleared, or if the ECM/PCM
has been reset, these readiness codes are reset to
incomplete. In some states, part of the emissions
testing is to make sure these codes are set to complete.
If all of them are not set to complete, the vehicle may
fail the emission test, or the test cannot be finished.
To check if the readiness codes are set to complete,
turn the ignition switch to ON (II), but do not start the
engine. The MIL will come on for 15 20 seconds. If it
then goes off, the readiness codes are set to complete.
If it flashes five times, one or more readiness codes are
not set to complete. To set readiness codes from
incomplete to complete, do the procedure for the
appropriate code.
To check the status of a specific DTC system, check the
OBD status in the DTC MENU with the HDS (see page
11-8). This screen displays the code, the current data list
of the enable criteria, and the status of the readiness
testing. NOTE:
 Do not turn the ignition switch to LOCK (0) or ACC (I) during the procedure.
 All readiness codes are cleared when the battery is disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
 Low ambient temperatures or excessive stop-and-go traffic may increase the drive time needed to switch
the readiness code from incomplete to complete.
 The readiness code will not switch to complete until all the enable criteria are met.
 If a fault in the secondary HO2S system caused the MIL to come on, the readiness code cannot be set to
complete until you correct the fault.
 ECT SENSOR 1 at 70 °C (158 °F) or more.
 IAT SENSOR at 7 °C (20 °F) or more.
 Vehicle speed (VSS) above 40 km/h (25 mph). 1. Connect the HDS to the vehicle’s data link connector (DLC), and bring up the READINESS
CODEs screen for Catalyst in the DTCs MENU.
2. Start the engine.
3. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. After about
8 km (5 miles), the readiness code should switch to
complete.
4. If the readiness code is still not set to complete, check for a Temporary DTC with the HDS. If there is
no DTC, one or more of the enable criteria were
probably not met; repeat the procedure.

11-70Fuel and Emissions Systems
How to Set Readiness Codes (cont’d)
NOTE: All readiness codes are cleared when the battery
is disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
 Battery voltage is more than 10.5 V.
 Engine at idle.
 ECT SENSOR 1 and ECT SENSOR 2 between 80 °C (176 °F) and 100 °C (212 °F).
 MAP SENSOR less than 46.6 kPa (350 mmHg, 14 in.Hg).
 Vehicle speed (VSS) 0 km/h (0 mph).
 IAT SENSOR between 0 °C (32 °F) and 100 °C (212 °F).
1. Connect the HDS to the DLC.
2. Start the engine.
3. Select EVAP TEST in the INSPECTION MENU with the HDS, then select the FUNCTION TEST in the
EVAP TEST MENU.
 If the result is normal, readiness is complete.
 If the result is not normal, go to the next step.
4. Check for a Temporary DTC. If there is no DTC, one or more of the enable criteria were probably not
met; repeat the procedure. NOTE:
 Do not turn the ignition switch to LOCK (0) or ACC (I) during the procedure.
 All readiness codes are cleared when the battery is disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
ECT SENSOR 1 at 60 °C (140 °F) or more. 1. Start the engine.
2. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. During the
drive, decelerate (with the throttle fully closed) for
5 seconds. After about 5.6 km (3.5 miles), the
readiness code should switch from incomplete to
complete.
3. Check the readiness codes screen for the air fuel ratio (A/F) sensor in the DTCs MENU with the HDS.
 If the screen shows complete, readiness is complete.
 If the screen shows not complete, go to the next step.
4. Check for a Temporary DTC. If there is no DTC, the enable criteria was probably not met. Select the
DATA LIST MENU. Check the ECT SENSOR 1 in the
ALL DATA LIST with the HDS. If the ECT SENSOR 1
is less than 60 °C (140 °F), run the engine until it is
more than 60 °C (140 °F), then repeat the procedure.
