DTC C0267 or C0268 and C067 or C068 ( EBCM is the electronic brake control module )
The EBCM applies the ground needed for pump motor activation. The low side of the pump motor has a feedback circuit to the EBCM. When the pump motor is commanded OFF and at rest, feedback voltage is high. When the pump motor is winding down after being commanded ON and then OFF, feedback voltage is low. The EBCM monitors this feedback voltage in order to determine if the motor is functioning properly.
DTC C0281 or C081
The stop lamp switch signal informs the electronic brake control module (EBCM) when the brake pedal is pressed.

2006 trailblazer is leaking transmission fluid, engine is chugging, and the check engine light is blinking.


Call the tow truck... you've got multiple issues going.
If you're good at troubleshooting, start. If not, get it to a mechanic.
Have you been regularly maintaining the vehicle? Did you hit a boulder or run over something? Check for undercarriage damage.

Just bought a 2006 chevy trailblazer. the engine light kees coming on. checked and replaced 2nd cylander coil. drove 150 miles engine light came ack on


I suppose the engine code said that cylinder was not firing or faulty? I would immediately get a compression check done on the engine. It is relatively painless. My burnt valves (compression 10psi vs 150psi) could not be diagnosed any other way. Does this help?
