I think for the next 5 to 10 years-- a Dealer will be the only place working on Hybrid's Pretty much have to go to school to work on them

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

Hello dear, have you found any effective ways to solve your problem? If you haven't, visit this website to know more information about generator tech. Generator Set Diesel Generator Cummins Volvo Perkins Generator

If you have a 12 volt test light check for power at the horn connector while having someone push the button... more than likely the horn is just dead.

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

yes it will as long as it is the same model transmission. As long as you get a transmission out of a standard cab truck you should be ok. ( for a good idea Most 88-98 gm trucks, full size blazers,jimmys,tahoes, and yukons will interchange) same chassis just different bodys and emblems

You likely have a HVAC control head failure. The rear heater problem is likely a door actuator, the rear wiper is likely a open wire in the door jamb in the top. The gauges are likely a cluster failure.

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

get a service manual

I had same problem on my 97 tahoe shut off while driving and wouldnt start only turned over. checked everything and when i replaced ignition module started right up no problem. Hope this helped and saved ya money

Motor relay circuit this is for the ABS, you will need ot restore the third eye brake light and check fuse in the engine junction fuse box, (cigarette lighter fuse) make sure it didnt open

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

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)
