![]() ![]() Please note, 08+ Automatics will have a transmission control module also, if sending in your PCM please include this.Īlso, check out our Aeroforce Scan Gauge – not only is this a helpful gauge for scanning many parameters, but it is capable of performing the CASE Relearn as well (if you are doing a core program). What program should I use and what is refundable? Click here! Express shipping only covers one shipment for loaner programs, the second will be returned via UPS Ground unless other arrangements are made. After placing your order, please click on fill out an order sheet for your vehicle ( here). We can account for most modifications you might have (2002-2005 year models: we are not able to make speedometer corrections or remove park/neutral rev limiter). Our tuning also helps with towing if you choose to do so. If you have an ‘08+ automatic, there is also a Transmission Control Module a 3x 3 silver box located right near the PCM. For 06+, it is a flat silver box, roughly 7x7, and is retained via a plastic holder. 02-05 PCM’s look like a small gray brick. Our performance tuning for the 4.2L I6 typically yields 10-14hp and 1-3mpg, as well as better throttle response, driveability, and more pep off the line. In the Trailblazer, the PCM is located on the driver’s side of the engine.

Old PCM is roasted, see attached picture when attempts are made to communicate after fixing the wiring problem An open ground or power (B+) circuit on a fuel-injected engine removes power from the ECM and prevents the engine from starting. I got another pcm no luck the brought a new pcm and new bcm. The problem is the u0100 no communication with pcm. I am sorry to hear about this issue and I understand it can be frustrating so I will try my best to help. Hey guys I got a 07 ss trailblazer I been working on for 3 months. Answered in 5 minutes by: Chevy Mechanic: AMEDEE. It uses throttle position data and engine speed to shift the vehicle at the right time. The TCM needs to communicate with the PCM (Powertrain Control Module) in order to know when to shift the transmission. I Need 2003 Chev Trailblazer PCM pin out diagram. The Transmission Control Module, or TCM, controls when and how hard the Chevy Trailblazer’s transmission shifts. PCM receives battery voltage (B+) through a fuse or fusible link. I Need 2003 Chev Trailblazer PCM pin out diagram. With the ignition key ON and bus activity, the voltage should vary from 0 to 5V depending on the amount of bus activity! With the ignition key ON and no bus activity, This tests the ECM Voltage supply as no power may be caused by a blown lighter fuseĬonnect positive DMM lead to either DLC bias terminalsĬonnect negative DMM lead to the ground terminal With the Ignition on, voltage on the class 2 serial data pin should be 5V or fluctuating between 3.5V and 5.0V, If open, PCM cannot transmit data to the scan toolĬonnect positive DMM lead to DLC Battery + terminalĬonnect negative DMM lead to battery ground terminal 8 (Green/Blue wire on 2. NOTE: An open circuit or high ground resistance means that the PCM will never enter diagnostic mode.Ĭonnect the positive DMM lead to the class 2 Serial Data pin and the negative DMM lead to either pin 4 or pin 5 or a known good ground Measure voltage between 16-pin PCM harness connector 'D', terminal No. With the ignition on, voltage drop across the ground terminal should be 0.1 Volts or less Transfer Case Shift Control Module: Behind lower left side of dash. Sun Roof Module: Above headliner, at rear of sun roof assembly. Powertrain Control Module (PCM) (5.3L) Near lower left front of engine. Do not connect to body or chassis ground but to the battery terminal directly The PCM (Powertrain Control Module) is tasked with controlling various aspects of your cars functionality and is essentially the brain of the vehicle. Powertrain Control Module (PCM) (4.2L) On upper left side of engine. If the scan tool does not receive data from an OBD II vehicleĬonnect the positive DMM lead to DLC pin 4 and the negative DMM lead to the negative battery terminal, using jumper wires if necessary. ![]()
