– If the fault persists, you can check the “Possible causes” listed above : visually inspect (by yourself (tutorials to come) or by a professional) the wiring harness and the associated connectors, check for damaged components, and look for broken, bent, pushed, or corroded connector pins.

What does U2106 code mean?

U2106 Lost Comm with Trans Control System

This GM specific “U” code means that the PCM cannot communicate with the transmission control system. This is most likely the result of a problem with the data line between the two or a failure of a module on the data line that injects voltage onto the line.

What does U2105 code mean?

U2105 CAN Bus Error ECM (GM specific code)

This GM specific code points to a problem in the high speed data line called the CAN bus. This data line carries digital information between modules. The problem can be a break in the line or a short in one of the modules that injects voltage onto the data line.

What is code P0AC4?

The P0AC4 error code would start indicating that hybrid powertrain control module has set an emission associated hybrid powertrain code. The hybrid powertrain control module would send a message via serial data circuit to the engine control module (ECM) requesting illumination of the Malfunction Indicator Light (MIL).

What is battery module deterioration?

The battery’s condition is monitored by dedicated control module, or electronic control unit (ECU). The ECU calculates the resistance (and therefore the condition) of the battery. If the ECU sees resistance has exceeded specification, it determines the battery has deteriorated.

How much is a hybrid powertrain control module?

How can I test my fuel pump relay?

Luckily, fuel pump relays are easy to test and replace on your own. Start by taking the fuel pump relay out of your vehicle so you can clean and inspect it. After that, you can use a multimeter to check the resistance going through the relay’s circuit to see if it’s faulty or not.

Which relay is for fuel pump?

The fuel pump relay is an electronic component that is found on virtually all vehicles equipped with an internal combustion engine. It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump.

How do you bypass the fuel pump relay on a Chevy truck?

Zitat von Youtube: Computer to control the on and off on the on the fuel pump relay. But if you just want to bypass that you just go directly through. And you just go uh pin 87 to pin 30 with the jumper.

How do you bypass a fuel pump control module?

Zitat von Youtube: These are going to the fuel pump. So if you jump right these wires right here these two outer wires together and the two grounds together it'll bypass. The control module.

What is fuel pump control module?

The Fuel Pump Driver Module controls the voltage delivered to a vehicle’s fuel pump. By controlling the voltage, the module maintains optimal fuel pressure and fuel delivery to the engine throughout its full operating range.

How do you bypass a fuel pump relay?

Zitat von Youtube: It's just a little jumper wire. But you could just use the wire. And be fine you don't really need the terminals on it.

Will the fuel pump run without a relay?

Yes, fuel pumps need a relay because it prevents your ignition switch from overheating. The run circuit (which the pump would traverse) was designed for a limited number of amps to transit through the contacts. It’s conceivable that adding fuel pumps, electric fans, and other accessories might burn up the connection.
