Your car is in Limp Mode - the computer of the car has detected a major failure in it and has reduced the performance to a level deemed low enough to allow your car to be driven to the nearest dealer. Take your car to one ASAP - more you wait , bigger the damage becomes , bigger the bill to fix it.

My 2012 Nissan Xterra doors keep locking while I'm driving. This also happens when it's park. Any suggestions on how to fix this problem?


That may be normal, all of my cars lock when going above about 15 mph and one of them locks when put in park, these were touted as a safety feature. Check with your dealer.

2008 jeep wrangler hood problem


I just bought a 2008 jeep wrangler and my hood is lifting 2 to 3 inches off the frame when I'm driving on the highway in wind speeds over 15 to 20 mph. I've owned two jeep wranglers in the past and I've never had this problem but chrysler keeps telling me this is normal. What's normal about a hood that is lifting off the frame?

Why is mybcm not letting me pass insp there is no code on thi1996 chry lhs what is going on


You mean PCM most states read the readiness monitors depending on the state on how many they allow not to be completed. The first one on the list that is hard to get run and pass is the EVAP Because this requires the car to be cold and fuel tank must between 15%-85% and both air temp and coolant temp with in 10 degrees of each other. Start car let idle for 5 -10 minutes Then drive car normally no hard accelerations or quick stops bring speed to 50-60 mph and coast down to 20-15 mph without brake pedal input repeat this twice.Then bring speed to 58-62 mph and set cruise control run for 12-16 miles exit freeway caught a red light or stop and idle 2 minutes shut car off rest for 5 minutes and repeat freeway drive. then redo morning cold start again . then have some one test the generic readiness monitors to what needs to run and attempt again. California before 2000 1 can be incomplete after 2000 all have to be completed which is hard some will not run for 800 miles.

How many times does a transmission supposed to shift starting from drive in a 1988 dodge ram with a 318 motor


Depends if you have a regular 3 speed automatic, or a 3 speed with overdrive.
Put it in drive, it will start out in first gear, then shift into second at about 15 MPH, into third at about 30-35 MPH. With overdrive, fourth gear will kick in at about 45-55MPH.

Tire pressure light is on ,how do I reset,lost my reset pages from manuel.


The tire pressure
monitor system can be reset two ways. With the ignition position at ON, pull the interior lamps control to the ON and OFF settings three times. It can also be reset through the radio using the
following steps:
1. Turn the ignition to ACC or ON and turn the radio off.
2. Press and hold the TUNE DlSP button on the radio for at least five seconds until SETTINGS is displayed.
3. Press the SEEK SCAN up or down arrow to scroll through the main menu.
4. Scroll until TIRE MON appears on the display.
5. Press the 1 PREV or 2 NEXT button to enter the submenu. RESET will be displayed.
6. Press the TUNE DlSP button to reset. A chime will be heard to verify the new setting and DONE will be displayed for one second.
7. Once the monitor has been reset, scroll until EXIT appears on the display.
8. Press the TUNE DlSP button to exit programming. A chime will be heard to verify exit.

The system completes the calibration process during
driving. The system normally takes 15 to 20 minutes of driving
in each of three speed ranges to "learn" tire pressures. The speed ranges are 15 to 40 mph (25 to 65 km/h), 40 to 65 mph (65 to 105 km/h) and above 65 mph (105 km/h). When learning is complete, the system will alert you after two to eight minutes if a tire is 12 psi (83 kPa) different from the other three tires. Detection thresholds may be higher and detection times may
be longer on rough roads, curves and at high speeds. The system is not capable of detection at speeds greater than 70 mph (110 km/h).

How do i reprogram the computer on my 2002 xl7


Try this relearn procedure hopefully it will help

Vehicles equipped with engine or transmission computers may require a relearn procedure after the vehicle battery is disconnected. Many vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When the vehicle battery is disconnected, this memory is lost. The computer will use default data until new data from each key start is stored. As the computer memorizes vehicle operation for each new key start, driveability is restored. Vehicle computers may memorize vehicles operation patterns for 40 or more key starts. Customers often complain of driveability problems during the relearn stage because the vehicle acts differently then before being serviced. Depending on the type of vehicle and how it is equipped, the following complaints (driveability problems) may exist:

Harsh Or Poor Shift Quality
Rough Or Unstable Idle
Hesitation Or Stumble
Rich Or Lean Running
Poor Fuel Mileage

These symptoms and complaints should disappear after a number of drive cycles have been memorized. To reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle should be road tested.

Vehicle Preparation

Ensure all components are connected. Ensure transmission fluid level is correct. Warm engine to normal operating temperature. If vehicle has been repaired, perform KOEO and Continuous Memory Code Self-Test and ensure fault codes are not present.

Computer Relearn Procedures

Idle Relearn Procedure

Place automatic transmission in Park or manual transmission in Neutral position. Ensure the emergency brake has been set and all accessories are turned off. Start engine and bring to normal operating temperature. Allow manual transmission vehicle to idle in Neutral for one minute. Allow automatic transmission to idle in Neutral for one minute and then to idle in Drive for one minute. Once initial relearn is complete, process will be completed during normal driving. Always complete the procedure before returning the vehicle to the customer.

Drive Cycle Test (AOD-E, AXOD & AXOD-E TRANSAXLES)

With transmission gear selector in Overdrive, moderately accelerate vehicle to 50 MPH for a minimum of 15 seconds. Transmission should be in 4th gear. While holding speed steady, lightly apply and release brake for about 5 seconds. Stop and park vehicle for a minimum of 20 seconds with transmission gear selector in Drive. Repeat procedure 5 times. Always complete the procedure before returning the vehicle to the customer.

Drive Cycle Test (E4OD)

With transmission gear selector in Drive, press Overdrive Cancel Switch (LED should light). Moderately accelerate vehicle to 40 MPH for a minimum of 15 seconds (30 seconds above 4000-ft. elevation) Transmission should be in 3rd gear. While holding speed steady, press Overdrive Cancel Switch (LED should go off) and accelerate from 40 MPH to 50 MPH. Transmission should shift from 3rd gear to 4th gear. Hold speed steady for 15 seconds. While holding speed steady, lightly apply and release brakes enough to turn brake lights on. Maintain 50 MPH for about 5 seconds. Stop vehicle for a minimum of 20 seconds with transmission gear selector in Drive. Repeat procedure 5 times. Always complete the procedure before returning the vehicle to the customer.

Ect power?


The ECT button stand for Electronically Controlled Transmission. In short, what the button does is change the upshift points for the auto trans. Normally, the 1-2 upshift is at 15-19 mph, pressing the button changes the shift mph form 15-19 to 19-22/23. More often than not, this feature wiooould be used if you are hauling a heay load, and the ECT gets you up to speed faster, via the longer time as mentioned above re the shift mphs. Not very useful with normal driving, it really does not do much without a heavy load.
