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.

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

11-71
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.
1. Start the engine, and let it idle for 1 minute. The readiness code should switch from incomplete to
complete.
2. If the readiness code is still not set to complete, check for a Temporary DTC. If there is no DTC,
repeat the procedure.
 This readiness code is always set to available because misfiring is continuously monitored.
 Monitoring pauses, and the misfire counter resets, if the vehicle is driven over a rough road.
 Monitoring also pauses, and the misfire counter holds at its current value, if the throttle position
changes more than a predetermined value, or if
driving conditions fall outside the range of any
related enable criteria.
 This readiness code is always set to available because the fuel system is continuously monitored
during closed loop operation.
 Monitoring pauses when the catalytic converter, EVAP control system, and A/F sensor monitors are
active.
 Monitoring also pauses when any related enable criteria are not being met. Monitoring resumes when
the enable criteria is again being met.
This readiness code is always set to available because
the comprehensive component monitor is continuously
running when ever the engine is cranking or running. 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 80 °C (176 °F) or more. 1. Connect the HDS to the DLC.
2. Start the engine.
3. Drive at a steady speed with the A/T in D position or M/T in 4th gear, at 80 100 km/h (50 62 mph) or
above for more than 10 seconds.
4. With the A/T in D position or M/T in 4th gear, decelerate from 100 km/h (62 mph) or above by
completely releasing the throttle for at least
5 seconds. If the engine is stopped during this
procedure, go to step 3 and do the procedure again.
5. Check the OBD status screen for DTC P0401 in the DTC’s MENU with the HDS.
 If it is PASSED, readiness is complete.
 If it is not PASSED, go to step 3 and retest.

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 If the misfire is frequent enough to trigger detection of increased emissions during two consecutive
driving cycles, the MIL will come on, and DTC P0300
(and some of the combination of P0301 thr ough
P0304) will be stored.
 If the misfire is frequent enough to damage the catalyst, the MIL will blink whenever the misfire
occurs, and DTC P0300 (and some of the combination
of P0301 through P0304) will be stored. When the
misfire stops, the MIL will remain on.

Electronic Control System (cont’d)
S Position Automatic Shift Mode and Sequential Sportshift Mode
14-44 Automatic Transmission
System Description (cont’d)
SHIFT INDICATOR
’’M’’ INDICATOR
The S position has two shifting modes; the automatic shift mode and the sequential sportshift mode. In the S position
automatic shift mode, the transmission upshifts and downshifts automatically from 1st through 4th gear, and the
paddle shifters are ready to be activated to switch to the sequential sportshift mode. In the automatic shift mode, the
shift indicator and the M indicator in the gauge control module (tach) do not come on.
When the paddle shifter (upshift switch) or the paddle shifter (downshift switch) is pressed, the automatic shift
mode is canceled and the sequential sportshift mode comes into operation. The shift indicator displays the number of
the selected gear, and the M indicator comes on. In the sequential sportshift mode, the driver can shift up and down
manually from 1st through 5th gear by using the paddle shifters, much like a manual transmission. The paddle shifters
are installed on the back of the steering wheel, and the driver can shift gears by pressing the paddle shifters without
taking either hand off the steering wheel.
In the sequential sportshift mode, the transmission must be shifted up and down by pressing the paddle shifters.
However, the transmission cannot downshift and stays in the current gear if the paddle shifter is pressed while the
vehicle is coasting at a speed that would cause the engine to over-rev by downshifting the transmission, and the shift
indicator blinks the number of the selected gear several times, then returns to the number of the current gear. If the
vehicle speed reaches an appropriate speed while the shift indicator is blinking the number of the selected gear, the
transmission downshifts and the shift indicator displays the selected gear. The transmission also cannot upshift and
stays in the current gear if the paddle shifter is pressed while driving below an appropriate upshifting speed, the
shift indicator blinks the number of the selected gear several times, then returns to the number of the current gear. If
the vehicle speed reaches an appropriate upshift speed while the shift indicator is blinking the number of the selected
gear, the transmission upshifts and the shift indicator displays the selected gear.
This mode has automatic downshifting areas so the vehicle can run smoothly with more power to cope with upcoming
acceleration. When coasting in 5th gear or 4th gear, the transmission downshifts to the next lower gear if the vehicle
slows down to the programmed speed, or by pressing the brake pedal.
When the transmission decelerates to a stop, the transmission shifts to 1st gear automatically. The transmission can
be shifted to 2nd gear by pressing the paddle shifter while the vehicle is stopped, and the vehicle can start off in 2nd
gear.
The sequential sportshift mode is canceled when moving the shift lever to any position other than S.

The shift lock system prevents the shift lever from mis-shifting. The shift lock solenoid is usually OFF. After starting
the engine in P, the shift lever ca
nnot move to any other position from P because the shift lock stop stops the lock pin
unless the brake pedal is pressed. When the brake pedal is pressed and the accelerator pedal is not pressed, the shift
lock solenoid is ON; the shift lock solenoid plunger in the shift lock solenoid pulls the shift lock stop to release the lock
pin. Pressing the shift lever button, allows the shift lever to move to any other position. When the brake pedal and the
accelerator pedal are pressed at the same time, the shift lock system is not unlocked.
