2007 GMC Sierra Technical Service Bulletins

230 technical service bulletins (TSBs) are on record for the 2007 GMC Sierra. TSBs are notes manufacturers send to dealers about repair procedures for issues seen in the field. They are not recalls and do not by themselves mean a vehicle has a fault.

• 10019434Aug 1, 2009Engine cooling. Diesel engine glow plug trouble codes. *tt updated 3/15/10.
• 10032336Jul 1, 2009Brakes, Air bags. Gmc/cadillac/chevrolet: air bag readiness light on, service air bag message, inflatable restraint sensing and diagnostic module (sdm) corrosion (replace sdm/cut and remove carpet pad).
• 10030123Jul 1, 2009Engine cooling. General motors: lbz, lly, lmm mil/ses light n dtc p0087-fuel rail pressure (frp) too low, lack of performance, no power, engine runs rough, no start (diagnose fuel system components). *pe updated 3/1/10.
• 10032889Jun 1, 2009Engine cooling. Gmc/chevrolet: dtc p0101 with non gm air filter. May encounter concern of reduced power and ses light on. Diagnostics may reveal maf (mass air flow) sensor dtc p0101. If diagnostics were inconclusive its possible dtc p0101 is setting due to a non gm air filter. Non gm air filters have shown a slightly higher than normal maf reading.
• 10032888Jun 1, 2009Engine cooling. Gmc/chevrolet: engine coolant sensor dtcs p011a, p2184, and p2185. Dealer may encounter concern of ses light on or dtcs p011a, p2184 and p2185. Diesel engines have 2 ect (engine coolant temperature) sensors.
• 10032866Jun 1, 2009Electrical system. Gmc/chevrolet/cadillac: sir mil on with dtc b1325 sym 03. During a low battery/voltage condition the passenger presence system may set a b1325 sym 03 along with other faults that are caused by the low batter/voltage condition.
• 10030750May 1, 2009Air bags. Gmc/chevrolet: sir mil on and tech 2 will not communicate with sdm. Some modules may set a communication dtc u0151 against sdm. Diagnostics may lead to replacement of sdm and replacing sdm may fix the concern for a short time or it may fail again on the first or second ignition key cycle. The hd silverado and sierras only.
• 10030724May 1, 2009Engine cooling. Gmc/cadillac/chevrolet: check engine light on, engine misfire, hard start, rough idle, hesitation, loss of power, poor performance, noise, dtcs p0300, p0301, p0302,p0303, p0304, p0305, p0306, p0307, p0308 set (replace engine).
• 10030110May 1, 2009Electrical system, Engine cooling, Fuel system. General motors: malfunction indicator lamp (mil) illuminated, intermittent dtc p0191, slow fuel rail pressure (frp) decay, wiring harness connections, voltage fluctuations/interruptions (follow correction information below). *pe updated 11/23/09.
• 10030207Apr 1, 2009Engine cooling. Chevrolet/gmc: diesel engine turbo dtc p2563 or p003a. May encounter a concern of ses light, reduced power, low power.
