The following "universal" drive cycle can be used as a guide to assist with re-setting monitors when a vehicle specific drive cycle cannot be located. This generic OBDII drive cycle begins with a cold start (coolant temperature below 122 degrees F and the coolant and air temperature sensors within 11 degrees of one another). This condition can be achieved by allowing the vehicle to "sit" overnight, and then by beginning the drive cycle the next day. Most drive cycles will be difficult to follow exactly under normal driving conditions, so the driver should exercise caution, road safety, and courtesy to others. # # 1. Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on. # 2. Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. # 3. Hold at a steady speed of 55 mph for three minutes. # 4. Decelerate (coast down) to 20 mph without braking or depressing the clutch. # 5. Accelerate back to 55 to 60 mph at ¾ throttle. # 6. Hold at a steady speed of 55 to 60 mph for five minutes. # 7. Decelerate (coast down) to a stop without braking.
There are two main causes for the readiness monitors being set to not ready: One, your battery was disconnected and reset the monitors; or your monitors were reset intentionally, such as having your check engine light (MIL) reset by someone using a scanning tool
THe drive cycle is a procedure used to set up the vehicles readiness monitors in order to prepare it for a state inspection.
Cars and trucks 1996 and newer are OBD2. You must run the OBD2 drive cycle yo reset the readiness monitors. The drive cycle varies among manufactures. Some garages can give you a print out of what you need to do. Keep running it, take it on the interstate and through town, some cars take a few hundred miles to set the monitors. Load up the family or take some friends and go on a road trip might as well have fun while resetting the computer.
Some cars are temperamental, to reset the computer so that the readiness monitors have reset you have to run the OBD2 drive cycle. The drive cycle varies from makes and models. It takes time, run it on the interstate as well as, in town. most part stores will scan for codes for you, if P1000 code is gone then you are good to go. P1000 means that the OBD2 checks are not complete. it will be gone when they are set.
most code readers will also erase the code(s), which will turn off the ce lite. HOWEVER, this also resets readiness monitors. the car then has to go thru several different running stages, like high speed, stop and go, etc. until all system readiness monitors are active, you cannot pass state inspection. also, after all system readiness monitors are active, most likely the ce lite will again illuminate. so, the absolute best way to turn off the check engine lite is to FIX THE PROBLEM.
In assessing readiness after an incident is over, and deciding what you want to do differently next time, set goals regarding:
prepared,set,all set,geared up. -V- _
The OBD designation refers to the emission system. OBD 1 was a simple one O2 sensor system the only monitored the exhaust gases at one point. OBD2 is an emission system that monitors several points in the emissions and exhaust.
It can be almost immediate depending on which monitor. The amount and specific monitors vary between autos. Some monitors will not run if there is a different monitor that fails. Typically, there is a drive cycle that must be performed for all of the monitors to set. This also varies from car to car. In most instances the cooling system and fuel temperature must be ambient or the same before beginning. Unless your car has a fuel temperature sensor, the drive cycle must start from a cold start. This can be a tough operation to perform and complete due to other traffic or speed limits or signals. If you are unable to follow it, all the monitors do not reset.
That requires an OBD2 engine scanner to set the timing.
logistics readiness is just one of the 5 key measurement areas of operational readiness. The other 4 areas are: personnel readiness, training readiness, equipment maintenance readiness and life support system readiness
Scan the ECU with an OBD2 scan tool to retrieve the code that has been set.
