The ABS EBCM anti-lock brake module is failing causing problems with the ABS pump running constantly, also will drain your battery.

  1. Remove the ABS fuse to prevent ABS motor burn out.
  2. You can still drive your vehicle with the module removed.
  3. We recommend covering the exposed surface of the hydraulic control unit with aluminum foil to keep out water and dirt.
Common Failures:
  • ABS Pump Always Running
  • Codes: C0265, C0267, C0268
  • Pump Motor Circuit trouble code
  • Power Relay trouble code
  • Valve Relay Trouble code
  • Dump Valves (solenoids) trouble codes
  • No Communication
  • Intermediate power loss

This is refering to your ABS. Test your EBCM (Electronic Brake Control Module) as this will most likely be your problem.

SOURCE: 2001 GMC SIERRA . ABS LIGHT STAYS ON

Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem

ABS light is on 95 GMC sierra k2500 4x4 light was on before i did a brake job on all 4 wheels how do you turn it off


Doing a brake job has nothing to do with the ABS system .There are three or four wheel speed sensors , depending on the type system . A EBCM - electronic brake control module controls the system .An if the light is on there is DTC - diagnostic trouble code stored in the EBCM ! A diagnostic tool that can read these codes has to be hooked up the vehicle to see what code is stored an then diagnosed . If you are unfamiliar with this your best bet would be to take your vehicle to a qualified repair shop . There is no just turning it off .

Why does my abs makes a noise when engine is off


Your ebcm internal relay is likely failed, possibly has a c0265 code in ebcm. Pull the abs maxi-fuse underhood fuseblock, abs and red brake light will come on, but noise should stop. There are several module rebuilders online (module masters comes to mind)

05 trailblazer 4.2 Multiple codes Po106, po305, po463, po128, po856 Co298,c0237,c0265,c0245,246, c0241,c0242, c0251,52,c0247,co243 WTF could all this mean


Hi Candice, .How does it run ? P0305 is a misfire code for cylinder #5, P0106 The manifold absolute pressure (MAP) sensor responds to pressure changes in the intake manifold. The pressure changes occur based on the engine load. The MAP sensor has the following circuits:
5-volt reference circuit
• Low reference circuit
• MAP sensor signal circuit
DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature
C0237
The EBCM detects an erratic rear wheel speed signal for 105 milliseconds.
DTC C0265 EBCM Motor Relay Circuit
C0265
Thoroughly inspect connections and circuitry that may cause an intermittent malfunction.
• DTC C0241 EBCM Control Valve Circuit
• DTC C0242 EBCM Control Valve Circuit
• DTC C0243 EBCM Control Valve Circuit
• DTC C0244 EBCM Control Valve Circuit
• DTC C0245 EBCM Control Valve Circuit
• DTC C0246 EBCM Control Valve Circuit
• DTC C0247 EBCM Control Valve Circuit
• DTC C0248 EBCM Control Valve Circuit
• DTC C0251 EBCM Control Valve Circuit
• DTC C0252 EBCM Control Valve Circuit
• DTC C0253 EBCM Control Valve Circuit
Sure looks like the ( EBCM ) Electronic Brake Control Module needs to be replaced .All these codes mean The EBCM detects an internal malfunction. Is the abs light on ?

I HAVE A CODE C0265 ABS BRAKE. IT SAYS BAD GROUND CHANGED BOTH HELP? 2003 YUKON XL


GM states this code is for the ebcm electronic brake control module, I have replaced alot of these over the years the motors short internally and the entire assembly must be replaced. sometimes the main abs fuse will pop and you replace it only for it to pop again because motor in side is shorted to ground.

Where are the ground wires for the ecbm gmc safari 2005


Diagnostic Test Code (DTC) C0265 is a POWER circuit code for the EBCM/Pump Motor Relay, not a ground code. This DTC sets when the voltage (B+) is too low at the EBCM when the solenoids and pump motor are commanded OFF. The voltage is supposed to be pulled low when the circuit is commanded ON. A ground problem with the EBCM is most likely to cause a failure of the EBCM to communicate with a scan tool. However, it doesn't hurt anything to check the ground. The main ground for the EBCM (G106) is located on the left rear of the engine near the knock sensor.

I have a 2000 GMC Sierra. Brake Light and ABS warning light comes on frequently. Sometimes it's there othertimes not. Have replaced the sensors, replaced rotors and pads, cleaned gound on the frame...


I would recommend checking for diagnostic trouble codes in the ABS system. If there is a diagnostic code C0265 set, then you're most likely looking at an ABS computer replacement. This is a common failure on these trucks. GM calls this computer an EBCM, or Electronic Brake Control Module. This is the controller for antilock brakes and is mounted directly to the ABS pump motor assembly. Last time i checked, these things were going for about $900 at the dealer.

Abs light is on


When the ABS (Anti Lock Brake System) light is on it means the systems control module has detected a failure and the ABS is disabled, this means you just have regular non ABS brakes. To find out what the fault is requires the ABS control module be scanned with a special tool to see what fault codes show up.
