Why do i get OBD/READINESS, Not ready?


Alan, I f you have had battery disconnected or had some one erase codes recently, the computer has to go through what is known as a drive cycle to complete all monitors cycling, some vehicles complete cycle in 10 miles, where as some could take 100 miles or more.
My Toyota EVAP readiness state will not cycle in cold weather and takes thousands of miles before it gets to readiness state.
I think some shops can force systems to run if they have a good scan tool.

Your vehicle is equipped with an OBD II computer AND a link to connect OBD II computer to a Smog Check Analyzer or Data Scan Tool (available
at most auto part stores).There are two types of codes, bad codes and good codes. The good codes are the "Readiness Flags". These Readiness Flags
indicate that certain emissions systems which the OBD II computer has been monitoring have PASSED the test, indicating that those systems are
working properly. Then there are the bad codes. The bad codes are actual "Trouble Code". These codes indicate that the OBD II computer
has detected a problem with in the emissions system. The Trouble Code will specifically indicate the component and problem which was found.
Newer vehicle's have very complex codes in the thousands.
"Readiness Flags" do not cause the "Check Engine" light to illuminate, but may cause a vehicle to fail the smog test.
In order to set all the proper "Readiness Flags" the OBDII system must complete at least one drive cycle (in some cases
two or three). A drive cycle is a sequence of internal tests which the OBDII computer runs while your vehicle is being driven. This insures
all emissions systems are functioning properly. Only then will your vehicle pass the smog inspection. A drive cycle usually requires one
week of driving.

Wats the code p1000 on my 2002 jaguar x type


P1000 JAGUAR - On Board Diagnostic System Readiness Test Not Complete, this is known as the OBD2 drive cycle.


Possible causes - The vehicle is new from the factory.
- Battery or Powertrain Control Module (PCM) had recently been disconnected.
- An OBD monitor failure occurred before completion of an OBD drive cycle.
- PCM Detected Trouble Codes (DTC) have recently been cleared with a scan tool.
When is the code detected? If DTC P1000 is triggered after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles have not been cleared. P1000 JAGUAR Description The On Board Diagnostic (OBD) monitors are performed during the OBD Drive Cycle. P1000 is stored in continuous memory if any of the OBD monitors do not carry out their full diagnostic check.

Here is the drive cycle procedure for that vehicle, and let me know if you require any further assistance.


Running an OBD-II Drive Cycle

The purpose of the OBD-II drive cycle is to run all of the onboard diagnostics. The drive cycle should be perfomed when any trouble codes are erased from the PCM or if the battery was dis-connected. Performing the drive cycle will reset the monitors so that any further trouble codes can be detected.

The OBD-II system drive cycle begins with a cold start with the coolant temperature below 120 degrees F. and the coolant and the air temperature sensors within 10 degrees of each other. (The ignition key must not be "on" or in the "Run" position until the cold start or the heated O2 sensor diagnostic might not start)

1. As soon as the vehicle starts up, idle the engine in drive for two and a half minutes with the AC and the rear defrost on if equipped with a rear window defroster. The OBD-II will check the O2 sensor circuits, the air pump, and the EVAP purge.

2. After the two and a half minutes turn off the AC and the rear window defrost, and then accelerate to 55 mph at half throttle. OBD-II checks for any ignition mis-fires, fuel trim, and canister purge.

3. Hold steady at 55 mph for three minutes. OBD-II monitors the EGR system, the air pump, the O2 sensors and the canister purge.

4. After the three minutes decelerate down to 20 mph without using the brakes or the clutch. OBD-II checks the EGR and the purge functions.

5. Accelerate back up to 55 mph at half throttle. OBD-II checks for mis-fires, fuel trim, and purge functions again.

6. Hold steady at 55 mph for five minutes. OBD-II will monitor catalytic converter efficiency, for any mis-fires, EGR function, fuel trim, O2 sensor operation, and purge functions.

7. Decelerate to a stiop without using the brakes or the clutch. OBD-II makes a final check of the EGR system and the canister purge functions.

After replacing battery OBD shows computer not


It usually take a few days and a few dozen miles for all the rediness monitors to reset. The car must go through different types of drive patterns during this time, including stop and go traffic, steady highway driving, a few quick accelerations, and quick stops.
