How do you change imrc on 2007 jeep compass

try reading the FSM? yet

or at for 15 bucks?

it all there, every day ,all the time. no need to wonder.

or join jeep forum.?

it unscrews,

and screws back on.

but the real question is, is it needing calibration. during or after.

replacing it is childs play, youtube that, bingo?

did you do all 25 test in the FSM, yet, on iRMC

even making sure the flapper is not jammed??????

if yes, and the actuator is really bad,

read this in the last page .

If the Manifold Flow Valve is replaced, a non volatile memory reset must be performed to learn the new port flap adaptive values.

now more lil\'horrors.. see what happens if you jerk the battery


Vehicles equipped with engine and transmission computers may require a relearn procedure after the vehicle battery has been disconnected. Most vehicle computers memorize and store vehicle operational patterns. When the battery is disconnected, the information may be cleared. If the information is cleared, the computer will go into default mode in order to operate the vehicle. The vehicle computer will relearn operational patterns each time the vehicle is restarted. The relearning process may take up to 40 or more key cycles.

When a specific engine component is replaced, a relearn procedure may be required. If the relearn procedure is not performed, the vehicle may exhibit the following:

  • Harsh or poor shift quality

  • Poor fuel mileage

  • Hesitation or stumble

  • Unstable idle or stalling

  • Lean or rich running conditions

If an accessory component was replaced, a relearn procedure may also be required. The following systems and components may not work properly without a relearn procedure:

  • Anti-theft system

  • Steering system

  • Power window system

  • Power sunroof system

It is important to reset any Diagnostic Trouble Codes (DTC\'s) before performing the relearn procedure. Most relearn procedures can be performed with the use of an OBD-2 scan tool.


This reconnection procedure is to be performed anytime the battery has been disconnected.

  1. Connect the battery negative cable to the battery post and tighten the clamp nut to 45 inch lbs. (5 Nm).

  2. If the vehicle is equipped with Electronic Stability Program (ESP), once the battery is reconnected, the Steering Angle Sensor (SAS) in the clockspring needs to be calibrated.


    The SAS requires calibration anytime the battery or an ABS (ESP) component has been disconnected for any length of time. If the SAS is not calibrated following battery reconnection, the ESP/SAS indicator lamp is illuminated following 5 ignition cycles indicating the need for calibration.

  3. To calibrate, perform the following:

  4. Start the engine.

  5. Center the steering wheel.

  6. Turn the steering wheel all the way to the left until the internal stop in the steering gear is met.

  7. Turn the wheel all the way to the right until the opposite internal stop in the steering gear is met.

  8. Center the steering wheel.

  9. Turn off the engine.

How do you reset a stering angle sensor

did you read the FSM/
it covers all that, and more.
or at
did you follow all steps, including the Match marking?

ill try to find it....

here is the page that tells you what went wrong.
A service replacement clockspring is shipped with the clockspring pre-centered and with a molded plastic locking pin installed.
This locking pin should not be removed until the steering wheel has been installed on the steering column. If the locking pin is removed before the steering wheel is installed, the clockspring centering procedure must be performed.
When a clockspring is installed into a vehicle without properly centering and locking the entire steering system, the Steering Angle Sensor (SAS) data does not agree with the true position of the steering system and causes the Electronic Stability Program (ESP) system to shut down.
This may also damage the clockspring without any immediate malfunction.
Unlike some other Chrysler vehicles, this SAS never requires calibration.
However, upon each new ignition ON cycle, the steering wheel must be rotated slightly to initialize the SAS.
Determining if the clockspring/SAS is centered is also possible electrically using the diagnostic scan tool.
Steering wheel position is displayed as ANGLE with a range of up to 900degrs.
Refer to the appropriate menu item on the diagnostic scan tool.
Before starting this procedure, be certain to turn the steering wheel until the front wheels are in the straight-ahead position and that the entire steering system is locked or inhibited from rotation.

The clockspring may be centered and the rotor may be rotated freely once the steering wheel has been removed.
(at the least, read the rack R&R pages first)

Airbad error code 47

For a 99 626, the service information says that code '7' is for the passenger side airbag module. I know that your question says that you have a code '47', but the information has codes 1 / 2 / 3 / 6 / 7 / 11 / 12. It states "replace SAS module for codes not listed." The SAS module is the main airbag computer.

Where is the steerin column ground in a mercedes w 203

In the mb w 203, steering angle sensor (sas) is plugged in the multifunction module which is connected to the wiring harness through a snap on connector. The scan tool was constantantly indicating the fault in the sas where as on diassembly I found that one of the connector pin in the module was broken. I changed the module and the problem was fixed.

Abs and traction control lights do not shut off

Hello and welcome to JustAnswer, My name is XXXX *** I will be assisting you.... When the "Service Electronic Brake System" Message appears, its telling you that you have a fault in the ABS(Anti-Lock Brake System)...In order to properly diagnose your vehicle you will need to take it to a shop that has the capability to connect to the ABS Controller.. Once you get the codes, then I can tell you the diagnostics in order to repair your vehicle.. The repairs may range from a clockspring, speed sensor, ABS Module, SCCM, or just needs to be Updated...
Customer :

I did take it to a place and have them connect to the ABS sytem. I think this cost me around $100 with the assumption that it would go toward the repairs if needed. Nothing was done and the mechanic spoke to me personally saying that he thought the sensor could just have dirt or gunk on it but did not mention any codes coming up.
Brad :

Ok, if the light is on the system has codes in it... He may not have had the proper equipment to diagnose your vehicle... But if it says service electric brake system there is a code that is in it and in order to properly diagnose your vehicle, I will need that code... Your vehicle utilizes the newest type of communication which is Can-Bus...Alot of older vehicle scantools wont work with this type of system... You may need to take it to a dealership for them to pull the codes for you
Brad :

I have this case from Jeep, you cn read it and maybe you will understand why the codes are so important in diagnosting your vehicle.
Brad :
Case Number K56486465
Vehicle Issue ABS lamp on. Fault codes C1219 and U0126 logged in the ABS module.;The SCCM must never be replaced unless it has an internal fault related specifically to the SCCM module. If the following conditions are found: - fault codes C1219 and U0126 are logged in the ABS module - the SCCM has no internal faults (active or stored) - the ESP and ABS icons are on and - the Service Electric Brake System message appears The fix is relatively simple and does not require replacing an SCCM.
System or Component Will Not Clear,Will Not Reset,Will Not Turn Off;DTC / Error Message;ABS System,ABS Light / Anti-Lock Light;Yes - Continuously
Recommendation 1) Connect the Starscan tool to the diagnostic connector, power up the tool and set the ignition key to run. 2) Confirm C1219 and U0126 is stored or active in the ABS module. 3) Confirm no faults are active or stored in the SCCM. 4) Position the steering wheel so the tires are pointing straight ahead. 5) Use tool and go to the LID in the ABS or SCCM to observe SAS position. If greater than 360 degrees, you must re-center the SCCM/SAS. Fastest way to re-center the SCCM/SAS is: A) Remove knee blocker to access the steering column/intermediate shaft (I-shaft) knuckle bolt. B) Remove the bolt and slide the I-Shaft off the column shaft. C) While monitoring the SAS position with the tool, rotate the steering wheel at least 360 degrees so the angular position decreases towards 0 degrees (zero). Remember, if the tires are pointing straight ahead, we should be at 0 +/- 30 degrees, so we can reattach the I-shaft and tighten the bolt. D) Clear the faults in the ABS and turn the ignition switch off and then on twice to ensure the cluster warnings and respective faults do not reappear. If the fault reappears, refer to intermittent diagnostics. Please note that Service part numbers have been released to allow for the replacement of necessary components versus replacing the entire SCCM assembly.

Read a PO410 code,1996 850 GLT volvo, secondary air injection system malfunction. Where is this located?

The most common cause is either a bad air pump (under your battery tray) and/or a bad SAS check valve which is connected in to your exhaust next to the firewall in the engine compartment.  It could also be a bad relay for the motor.  Less common, but possible, other bad components are the vacuum solenoid that controls the SAS valve, which is located by the radiator or a broken/leaking vacuum line to or from the solenoid.

You can test the motor by jumping the relay or applying 12v straight to it.  If the motor runs it most likely is not the problem.  If not, it's likely that there is water in it and you should replace both the motor and SAS valve.  The SAS valve is a pain to get unbolted, at least on turbo cars.  You can check the solenoid by just making sure there is vacuum going to the SAS valve a few seconds after starting up the car cold, and checking the lines for any obvious wear in the rubber elbows or breaks in the plastic line.
