it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

SOURCE: 2003 GMC Yukon XL Denali Service Ride control info

leaking suspension air bags is the most common cause, but the system can be tested for trouble codes, I suggest u do so, only the dealer can do this, but guessing about what the problem is can get very expensive very fast.

SOURCE: service engine light staying on

Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.

SOURCE: gmc yukon has the abs & parking brake light

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem

SOURCE: How can you set up a secondary battery on 2007 Denali

carry a battery booster pack. they are like 50 bucks. Any eletrical modification you do to your vehicle and its not done by a gmc dealer, your eletrical (and possibly other) parts of your warranty will be voided. If you keep the booster pack charged, all you have to do is hook it to the terminals and your going again. You can also buy a bigger battery. Im sure they battery is already a monster, buy shop around and see if you can get a bigger (amps) one that fits your truck

2007 Yukon Xl Denali can the headlight switch/dimmer cause only the tail lights to not work. Dash lights, signals, brake lights when pressed work. Both sides went out. No blown fuse or broken wires.


If front park lights are working highly unlikely headlight switch is the issue. Is the vehicle equipped with a trailer towing package and wiring to the rear? I would start there. This vehicle may also have a taillight module located under the vehicle on the passenger rear attached in the wheel well area that goes bad

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern: Some customers my comment of a Service Park Assist Message on the DIC and/or the LED indicators at the right rear pillar staying on or inoperative. This concern could be caused by the wiring harness to the LED indicators being pinched under a ground eyelet at the right rear pillar, as shown below.

other issues could be the problem such as poor connections at each sensor or damaged sensors. to clear URPA codes,place ignition in run,(engine OFF),shift into reverse and turn key OFF.place shift lever into park and retest operation of URPA. if still inop URPA code(s) need to be retrieved before further diagnosis can be accurately done.

How do I get rid of my "Service Park Assist" message?


{: ) The "Service Park Assist" message cannot be erased or reset until the main cause of the problem is resolved. It will just keep on coming back. Let's say one or more of the park assist sensors are faulty, you should have it repaired or replaced first before the scan tool can successfully clear the trouble codes that were present then.
The SERVICE PARK ASSIST message is a reminder that a fault has been detected by the parking assist system and it will disable this system until the problem is being addressed. A scan tool can effectively trace the cause of the fault.

My park assit is on and the sensor are not working for backing up can they have dirt in them


{: ) The PARK ASSIST OFF message will be displayed when the parking assist system is disabled due to conditions that disable or inhibit the system. The object alarm module requests the DIC display PARK ASSIST OFF when it detects one of the following conditions:
• The parking assist system is manually disabled using the driver information center (DIC). • An object is attached to the rear of the vehicle, such as a trailer, bicycle rack, trailer hitch receiver, or tow bar. • The object alarm sensors are covered by snow, mud, dirt, slush, or ice. • The vehicle bumper is damaged. • Excessive paint thickness on a replacement object alarm sensor. • The object alarm sensors are disrupted by vibrations, like those caused by a large nearby vehicle or from heavy equipment such as a jackhammer.

The SERVICE PARK ASSIST message will be displayed when the object alarm module detects a malfunction in the parking assist system and the system is disabled. It could be one of your sensors is at fault or even the module.

I'm pulling a trailer and "Park Asst Blocked" light came on the dash. Is it ok to drive with that light on?


{: ) When the park assist system detects a hitched object behind your vehicle, it will normally display that "Park assist Blocked" message. You can still drive safely even with that message. When you're done, just remove the hook off. Turn off engine for a few minutes. turn it on again and drive your truck around for 30kmh or so, then test again the park assist system.

Park assist warning came on.


{: ) SERVICE PARK ASSIST The driver information center (DIC) displays SERVICE PARK ASSIST when the park assist module detects a malfunction in the object detection system and sends a request to the DIC for display of the message. The DIC also displays SERVICE PARK ASSIST when there is a loss of communication with the park assist module.
PARK ASSIST OFF The PARK ASSIST OFF message is displayed in the DIC when the park assist system is disabled due to conditions that disable or inhibit the system. The red LED in the rear display, as well as, the telltale in the switch will be lit, notifying the driver the PARK ASSIST system is disabled. The object alarm module requests the DIC via the serial data circuit to display PARK ASSIST OFF when it detects that one of the following conditions is true:
• The object alarm system is disabled through DIC vehicle customization feature. Refer to the Owners Manual for more information. • An object is attached to the rear of the vehicle, such as a trailer, bicycle rack, or hitch receiver. • An object is hanging out of the endgate. • The park brake is not fully released. • The system receives vibrations from a large nearby vehicle or from a heavy equipment such as a jackhammer. In the case of objects attached to the rear of the vehicle such as a trailer, hitch receiver, or a bicycle rack, or objects hanging out of the endgate, the rear parking assist (RPA) will have an Automatic Object induced disable feature where the RPA will determine if the rear object is moving with the vehicle. If the RPA detects such a condition, the park assist will be disabled. The PARK ASSIST OFF message will continue to be displayed until the trailer hitch receiver is removed and the vehicle is driven forward above 24 km/h (15 mph).
