Top 20 2013 Chevrolet Tahoe Questions & Answers

Try these reset procedures, but some newer models need a special dealer code.

Could be a fuse, check all fuses in all fuse boxes and if non are found bad... It could be anything from the control head to the rear blower motor of any thing in between. Does the rear fan work with the rear controls??

The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well. http://www.diy-gm-security.com/

That was a reset, try a relearn. You'll need a charger on the battery. Ten minutes on, thirty seconds off. Do this three times, then try to start. If that doesn't work, then it has to go on a scanner to see what happened. Sparks like yours usually don't hurt anything. But they can spike and burn a computer. Next time put the positive side on first.

You could have a parasitic drain. Something that is left on in the car and drains the battery. It could also be a corroded terminal on the battery where the alternator is not getting power to charge the battery . Clean the post and the connector of all deposits and install those felt washers under the terminals to impede further corrosion.

Out of gas? battery dead? not turning key? no idea.

well it is married to the PCM and the alien cluster is not allowed the cure is at the dealer. ,THE RE_marriage. magic, all modern cars, even the odometer is blocked, for this so hacker can not hack the odometer miles remember the old'n days as seller jacked up rear of car run it in reverse for a week rolling back the ODOM well this has progressively gotten more strict ( the marriage stuff) our service manual no read RTM is why you do not know this. a brave new world this is. (wish I can find a 1975 car) all are now stinking lowriders.(trash )

Question edited for clarity, 'year make model' first. This is one job, I would not do myself. The airbags are extremely dangerous if they go off, even if just reconnecting the battery. I would replace the impact sensors. Not sure if they are resettable, but I would replace anyway. Often, having the sensors reset and recalibrated is adequate. However, when the airbag does deploy, there's more to do than just replace the airbag. May 4, 2017

The importance of recalibration after airbag deployment

Its behind the cover on the right hand side dash. Open the passenger door and the cover is right there

no info generic answer check level and condition of trans fluid --check 4wd module--switch --check transfer case--check trans selector cable connector

get a service manual

Anti-theft system is software programmed into the vehicle modules (computers) PCM/ECM - engine computer , BCM - body control module. Your best bet , take it to a qualified repair shop. Passlock™ System The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key turns the lock cylinder. The cylinder rotation produces an analog voltage code in the Passlock™ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a class 2 message is sent from the BCM to the powertrain control module (PCM)/vehicle control module (VCM). The message enables the fuel injectors. The design of the Passlock™ system is to prevent vehicle theft by disabling the engine unless the ignition lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the PASS-Key® system. However, the Passlock™ system eliminates the need for a key mounted resistor pellet. The components of the Passlock™ system are as follows: • The ignition lock cylinder • The ignition switch • The Passlock™ sensor • The Body control module (BCM) • The security telltale • The vehicle/powertrain control module (VCM/PCM)

Fuel pressure? have you tested anything or just replacing parts?

I got this free Pdf manual from reliable-store. com for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 years

You need to do a hard reset of your clock. On the touchscreen, select "MENU", when the screen changes, touch the lower left corner and hold until the PIN screen appears. Now enter the PIN code 295660, touch "NEXT", "PAGE", then "SET TIME".

Sounds like one or both of the gas struts that hold the door up, are worn out.

Tow/haul mode enables the operator to achieve enhanced shift performance when towing or hauling a load. When tow/haul mode is selected, the tow/haul switch input signal to the body control module (BCM) is momentarily toggled to zero volts. This signals the powertrain control module (PCM) to extend the length of time between upshifts and increase transmission line pressure. Cycling the tow/haul switch again disables tow/haul mode and returns the transmission to a normal shift pattern. Would't trust it , take an have DTC'S - diagnostic trouble codes checked by a qualified repair shop with a factory or professional scan tool . Auto part stores can not check BCM code's . DTC B2722 Tow/Haul Switch/Indicator Always On or Inoperative Step Action Value(s) Yes No 1 Install a Scan Tool . Turn ON the ignition, with the engine OFF. Cycle the tow/haul switch while observing Tow/Haul Mode on the Scan Tool . Does the Scan Tool display Active when the switch is first pressed, and then Inactive when the switch is pressed again? -- Go to Intermittent Conditions in Engine Controls - 4.3 L or Intermittent Conditions in Engine Controls - 4.8 L, 5.3 L and 6.0 L Go to Step 2

If the engine stops revving at a certain RPM, it's probably a safety feature and you need to replace a sensor. On some cars, if a crankshaft or camshaft position sensor fails, the computer will guesstimate when to fire the spark plugs using information from the sensor that DIDN'T fail. But to protect the engine, the computer will only allow it to rev to a certain speed. The most common culprit is the crank position sensor -- try replacing that first. Probably pretty cheap online.

Under the hood in the power distribution/fuse box, it's on the driver's side between the firewall and the battery! Thanks and have a great day!

The wires could be shorting or have a bad connection any where in the length from the radio to the sub woofer. I lost all sound in my Tahoe and thought that the connection was at the radio but never found a problem. One day on a hard left turn a loose chair in the back area of the Tahoe struck the right side panel which has the speaker and everything starter working.
