![]() These plug into the under-dash OBD-II data link connector and make quick work of the task. Another option would be to check with nearby 4X4 specialty shops and see if they can use their tool on your vehicle for possibly a few less bucks. Q: I was wondering whether the 2001 GMC Sierra HD 2500 Dual Cab truck has ever had an electronic recall. I have an electronic problem that I noticed on at least two other, different GMC trucks I’ve ridden in. Specifically, the ABS/Brake light is almost always on the gasoline indicator works intermittently and the radio/clock almost never works. An Internet research brought up a possible problem: electronic cluster. Before I pay for an electronic diagnosis ($150), an electronic cluster (+$500), and installation fee, I wanted to get your input on this. Any ideas?Ī: I searched and was unable to find a service bulletin, OEM campaign, or recall that would tie any of these faults together, as well as any common physical connection. Certain Chevy and GMC trucks of your vintage were recalled for possible corrosion that might affect the ABS system’s front wheel speed sensors, resulting in undesired ABS intervention at low vehicle speeds. I think you may have three different situations. Retrieving diagnostic trouble codes from the ABS system should shed light on the cause of the illuminated warning indicator. When the fuel gauge doesn’t work, does it go to full or empty? This should help determine a possible cause. A scan tool check of fuel level (info from powertrain control module) versus the instrument gauge would guide a tech to perhaps the fuel tank sending unit as opposed to a possible instrument panel/gauge fault.
