2005 Cadillac DTS traction control light comes on

I replaced brakes and rotors recently and ever since the traction control light comes on and stays on. The dic code I get is c1295. All the connections look okay? You also can not turn the traction on or off when the light comes on. It's not on when I first start the car but within 2 to 5 blocks it comes on?
Do you
have the same problem?

Have you verified if the stoplamps function? C1295 relate to the stoplamps circuit. Here is the fault code chart for C1295.

DTC C1295
Circuit Description
The electronic brake control module (EBCM) sources 5 volts on the stop lamp switch signal circuit when the stop lamp switch is inactive. The voltage is supplied a ground path through the stop lamp bulbs.

DTC Descriptor
This diagnostic procedure supports the following DTC:

DTC C1295 Brake Lamp Switch Circuit Open

Conditions for Running the DTC
The ignition is ON.

Conditions for Setting the DTC
The stop lamp switch input voltage is between 2.1-5.3 volts for 2 seconds.

Action Taken When the DTC Sets
" The EBCM disables the traction control system (TCS) for the duration of the ignition cycle.

" The Traction Control indicator turns ON.

" The ABS remains functional.

Conditions for Clearing the DTC
" The condition for the DTC is no longer present and the DTC is cleared with a scan tool.

" The EBCM automatically clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Diagnostic Aids
Possible causes of this DTC are the following conditions:

" Check the resistance of the center high mounted stoplamp, the value should be less than 400 .

" A signal circuit of the stop lamp switch is open.

" The stop lamp switch is misadjusted.

" Verify proper stop lamp switch operation using the data list of the scan tool. As the brake is applied, the data list displays the stop lamp switch ON within 2.54 cm (1 in) of travel.

" All brake lamps are open.

" All brake lamp grounds are open.

" The circuit has a wiring problem, terminal corrosion, or poor connections.

" Loose or corroded EBCM ground or ECM ground

" An internal EBCM problem

Test Description
The numbers below refer to the step numbers on the diagnostic table.

This DTC detects an open stop lamp switch signal circuit from the stop lamp side of the splice pack to the EBCM.

This step verifies that the stop lamps are operating properly.

Did you perform the Diagnostic System Check - Vehicle?
Go to Step 2
Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

Press the brake pedal.
With the scan tool, observe the Stop Lamp Switch parameter in the DRP/ABS/TCS data list.
Does the Stop Lamp Switch parameter display Applied?
Go to Step 4
Go to Step 3

Test the signal circuit of the stop lamp switch for an open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?
Go to Step 7
Go to Step 5

Press the brake pedal.

Are all of the stop lamps ON?
Go to Step 5
Go to Stop Lamps Inoperative in Lighting Systems

Important: Refer to Diagnostic Aids before replacing the EBCM.

Inspect for poor connections at the harness connector of the electronic brake control module (EBCM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?
Go to Step 7
Go to Step 6

Replace the EBCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.

Did you complete the replacement?
Go to Step 7

Use the scan tool in order to clear the DTCs.
Operate the vehicle within the Conditions for Running the DTC, as specified in the supporting text.
Does the DTC reset?
Go to Step 2
System OK
