I have been changing the big green fuse in a box near the inside wall on passenger side. you have to take the battery out to see this box. i have had the fuse replaced 3 times and the light went off so i went to have it inspected and it did not pass because of the pump they say. i don't want to have to pay 300.00 just for this part. pam

A complete drive cycle for any computer controlled vehicle is cold-starting the vehicle, running the engine to full operating temperatures(this may require driving the vehicle), then turning the vehicle off and allowing the engine temperature to completely cool down again.
Performing a GM OBDII Driving cycle:

  1. Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 122°F (50°C) and within 11°F (6°C) of the ambient air temperature at start up. 
    Do not leave the key in prior to the cold start or the heated oxygen sensor diagnostic may not run. 
  2. Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heaterPassive AirPurge "No Flow"Misfire, and - if closed loop is achieved- Fuel Trim
  3. Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 55mph (88km/hr) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed. 
  4. Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed. 
  5. Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 20 mph (32km/hr). During this time the EGR, Purge and Fuel Trim diagnostics will be performed. 
  6. Accelerate. Accelerate at 3/4 throttle until 55-60mph (88-96 km/hr). This will perform the same diagnostics as in step 3. 
  7. Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst. 
  8. Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.
As to resetting your Computer, there is another way but it might erase all the DTC code. Buy if there are any problems they should show up again. 
Place the ignition to the run position and pull the ECM (Batt) fuse from the fuse panel by the drivers door. Place it back in after 2 min and start the Jimmy, the Engine is going to stall but don't touch anything and let it. Start it up again and the codes should be cleared and so is everything else like the day it was started for the first time. Go for a test drive but not to hard for the first 10 min and let the jimmy go through all it's gears.
The Computer just needs to re learn the Engine and Transmission again. You may notice if everything is fine that the gas mileage is better too.
Good luck and hope this helps.

Service code p0410 reset with battery disconnect


P0410 - Secondary Air Injection System Malfunction

What does that mean?
The P0410 code refers to the emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.

About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

Possibly symptoms include:
* MIL illumination obviously
* Hesitation on acceleration
* Noise from a bad/stuck AIR pump

Causes:
A code P0410 may mean that one or more of the following has happened:
* Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
* Blown AIR pump fuse due to freezing up

Possible Solutions:
Note: There is a technical service bulletin (TSB) regarding this code for a number of GM models. The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose. The TSB can be found on this ACDelco site.

Additionally, if you simply replace the AIR pump the problem may return again (and again). If you replace the pump, also clean out the hoses and replace the one-way check valve. If this is on a GM model that the TSB applies to, follow those instructions in the link above. In a few cases, people have put a small hole in the rubber cover on the pump which allows any water to drain out.

Also, please note that this may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!
* Replace the AIR pump AND one-way check valve
* Test and clean the AIR pump AND test and replace the one-way air check valve
* Replace the AIR pump inlet hose
* Replace the AIR pump fuse (found under the hood)


Check it and remember rated this.

We have a 2001 Jimmy GMC. Is there a way to see if the air pump is bad? Keep getting 410 code. It won't pass emissions?


P0410 is a fault of the A.I.R. pump and nothing else. AIR pump adds air to the exhaust stream to lower emissions. It does this by taking in outside air and pumping it through two one-way check valves into each bank of the exhaust. About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate,especially in the northeast with higher humidity, this water may be more excessive. The waterpartially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump isfrozen it cannot turn, thus overloading the circuit and "popping" the fuse. As far as the location of the fuse, it is in the right front fender well beside the battery, and in front of the horn thereSometimes replacing the fuse will fix all your problems and you are all set until next winter when it all happens again. GM says that when this system failure occurs due to water intrusion, the pump MUST be replaced. I have had decent luck just blowing the pump out with direct power provided by a test bettery out of the vehicle, and saving some money. Also, sometimes water is allowed to enter the pump through the intake side of the system (just a 5/8" hose behind the fan shroud) and ruins the system that way. GM has also released a remote air intake kit that includes a longer 5/8" hose, a control solenoid, and a one-way check valve to eliminate most possibility of water intrusion. Good luck and hope this helps, Keep me posted and be glad to help.

I don't think you have anything wrong, I just don't think you have completed the correct drive cycle yet. Some vehicles must be driven in a very specific way before all the monitors will set. Here is the drive cycle that Gm Recommends:

  1. Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 122°F (50°C) and within 11°F (6°C) of the ambient air temperature at startup.
    Do not leave the key in prior to the cold start or the heated oxygen sensor diagnostic may not run.
  2. Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire, and - if closed loop is achieved- Fuel Trim.
  3. Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 55mph (88km/hr) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.
  4. Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.
  5. Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 20 mph (32km/hr). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.

During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.
  8. Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.
