GMC Yukon XL 2000–2006

From the manufacturer’s document

• Applies to：Applies to 2022 and prior GM passenger cars and light duty trucks.
• Condition：Ride, handling and road noise concerns may be caused by improperly adjusted tire pressure.
• Confirm：The first step in diagnosing these concerns is to verify that the tires are inflated to the correct pressures.
• Confirm：The tire placard is on the driver's side front or rear door edge, the center pillar, or the rear compartment lid.
• Caution：The recommended inflation pressure is not the pressure printed on the tire sidewall.
• Confirm：Generally a 5.6°C (10°F) temperature change equals a 6.9 kPa (1 psi) tire pressure change.
• Confirm：A "cold" tire is one that has sat for at least 3 hours or been driven no more than 1.6 km (1 mi).
• Caution：Always inspect and adjust the pressure when the tires are cold.
• Condition：During cold weather the Tire Pressure Monitor (TPM) indicator (a yellow horseshoe with an exclamation point) may illuminate.
• Repair：If the indicator goes off after the tires warm up, reset the pressure to placard pressure at the cold temperature.
• Caution：Vehicles with different front and rear pressures need to be adjusted after tire rotation.
• Caution：To prevent electrostatic discharge damage to the Tire Pressure Monitoring Sensor (TPMS), the technician should be statically discharged before checking or filling tires.

From the manufacturer’s document

• Applies to：A Tire Pressure Monitor (TPM) system was added to certain GMC and Chevrolet full-size utility trucks for model year 2004 and continues for 2005.
• Condition：The Passenger Door Module (PDM) is the receiver in the full-size utility truck; the receiver module varies by vehicle platform.
• Condition："Check Tire Pressure" message: a sensor that detects a 1.6 psi (11 kPa) change in pressure transmits in re-measure mode; if the system detects a significant loss of pressure in any tire, the message is displayed on the DIC and the low tire pressure indicator is illuminated on the IPC.
• Caution：A "Check Tire Pressure" message does not set system codes; it is normal operation, meant to alert the driver to check and adjust tire pressure.
• Repair：Both the message and the indicator can be cleared by adjusting the tire pressure to the recommended pressure.
• Condition："Service Tire Monitor" message: if the PDM detects a malfunction in the TPM system, it causes the DIC to display this message.
• Confirm：The "Service Tire Monitor" message is not normal system operation; DTCs should be set when it is displayed.
• Confirm：Always check and adjust the tire pressures cold; as a rule of thumb, tire pressure changes one psi for every 10° F (6.9 kPa for every 5.6° C).
• Caution：Always relearn the system before replacing a suspect sensor.
• Repair：The tire pressure sensor relearn procedure must be performed after every PDM replacement, every sensor replacement and every tire rotation.
• Repair：J-46079 TPM Diagnostic Tool method: turn the ignition ON with the engine OFF and set the parking brake, then put the PDM in TPM learn mode by cycling the parking lamps ON and OFF 4 times within 4 seconds; the horn chirps and the low tire pressure indicator begins to flash.
• Repair：Proceed in the order left front, right front, right rear, left rear: starting with the left front tire, hold the antenna of the J-46079 against the tire sidewall close to the wheel rim at the valve stem and momentarily press the activate button.

From the manufacturer’s document

• Applies to：Tahoe/Yukon/Denali, model year 04: direct (RF) system, Learn procedure, by the exterior lamp switch and a pressure change, or with J-46079.
• Applies to：Suburban/Yukon XL/Denali XL, model year 04: direct (RF) system, Learn procedure, by the exterior lamp switch and a pressure change, or with J-46079.
• Condition：The direct type uses a pressure sensor/transmitter in each wheel and notifies the driver when a tire pressure is out of specification.
• Repair：After a tire rotation the direct system needs a learn procedure to identify the new location of each pressure sensor; refer to SI.
• Confirm：On some vehicles the CHECK TIRE PRESSURE and/or XX TIRE HIGH/LOW display cancels within 20 seconds of setting the pressure to specification; on others the DIC display can take up to 20 minutes, or cancels at 20 mph (32 km/h) or greater.

From the manufacturer’s document

• Applies to：Applies to 2005-2020 GM passenger cars and light duty trucks.
• Condition：A tire slowly loses air pressure over a period of days or weeks.
• Cause：Abrasive elements may intrude between the tire and wheel at the bead seat, and the relative motion between tire and wheel lets the particles wear the wheel and tire materials.
• Confirm：The corrosion may be on the inboard or outboard bead seating surface and is not visible until the tire is dismounted from the wheel.
• Caution：Do not replace a wheel for slow air loss unless the wheel has been evaluated and/or repair has been tried with this procedure.
• Confirm：After a water dunk tank leak test, if the source of the leak is around the bead seat of the wheel, dismount the tire to examine the bead seat.
• Confirm：Bead seat corrosion looks like blistering of the wheel finish, giving a rough or uneven surface on which the tire has difficulty keeping a proper seal.
• Confirm：For vehicles with 32,186 km (20,000 mi) or less, the total combined linear area of repairable corrosion is 100 mm (4 in) or less; beyond that the wheel should be replaced.
• Confirm：For vehicles that have exceeded 32,186 km (20,000 mi), the total combined linear area of repairable corrosion is 200 mm (8 in) or less.
• Repair：Use a clean-up (fine cut) sanding disc or biscuit to remove the corrosion and any flaking paint, back to material that is stable and firmly bonded to the wheel.
• Repair：Once the corrosion is eliminated, coat the repaired area with a commercially available tire sealant such as Patch Brand Bead Sealant or equivalent.
• Parts：Part number 16118, Patch Bead Sealer (1 Quart (= 0.946 L)).

From the manufacturer’s document

• Applies to：Applies to 2006-2014 GM passenger cars and light duty trucks.
• Condition：It is a procedure for dealership service consultants when a customer arrives with the low tire light on or reports a check tire pressure, low tire pressure, add air to tire or service tire monitor system message.

From the manufacturer’s document

• Applies to：All brands and models, model years 1995 - 2020.
• Condition：The document gives the steps for downloading or updating the AFIT, TPM, GR8, MIT, PICO Scope or VDR tools.

From the manufacturer’s document

• Applies to：Applies to 2022 and earlier GM passenger cars and light duty trucks.
• Applies to：Only some vehicles built prior to the 2008 model year have tire pressure monitoring; check vehicle build and RPO information to be sure.
• Condition：A Check Tire Pressure / Low Tire Pressure message or light stays on solid with no system codes set; the system is operating as designed and correcting the tire pressure resolves it.
• Condition：A Service Tire Monitor message or light blinks and system codes set; this is a condition to be diagnosed and corrected.
• Cause：If one or more tire pressure sensors do not transmit for 18 minutes of driving, the system sets a code, displays a message and blinks the light for about a minute, after which it stays on solid for the rest of the ignition cycle.
• Condition：The Low Tire telltale must come on when a tire's pressure drops to 75% of the Recommended Cold Inflation pressure.
• Cause：A low pressure warning can appear when tires were rotated and pressures adjusted but the new positions were not re-learned, on vehicles with different placard pressures front and rear.
• Repair：Re-learn the TPM sensors and adjust the tire pressure to the placard values after every tire rotation.
• Caution：Never set the tire pressure below the placard value regardless of tire or ambient temperature.
• Confirm：When activating a sensor, place the antenna tip of the EL 52545 tool on the sidewall, perpendicular to the tire and close to the valve stem.
• Caution：To prevent electrostatic discharge damage to the tire pressure sensor, the technician should be statically discharged before checking or filling tires.
