Hey guys,
I have a couple current codes I need help with.

For the PCM, I have a P0410 code which is the the AIR system and then a P1626 code which is the "Theft deterrent system fuel enable circuit". Im wondering what needs to be done to fix these codes? I no longer have an air system, btw.

For the TCS, I have a C1296 code which pertains to the brake master cylinder. What is a fix for this?

Thanks guys

 

? Anyone ?

 

DTC C1296 Master Cylinder Sensor Circuit Open or Shorted




Circuit Description
The EBCM uses input from the Brake Pressure Sensor for more accurate control during an Active Handling event.

Conditions for Setting the DTC
DTC C1296 can be set anytime the ignition switch is in the ON position, and the signal voltage from the Brake Pressure Sensor is less than 0.20 volts or greater than 4.80 volts.

Action Taken When the DTC Sets
ABS and TCS remain enabled, Active Handling™ is disabled.

Indicators that turn on: Car Icon (TCS indicator)
Messages displayed on the DIC: Service Active HNDLG
Conditions for Clearing the DTC
Condition for DTC is no longer present and scan tool clear DTC function is used.
Fifty ignition cycles have passed with no DTCs detected.
Diagnostic Aids
It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
An intermittent malfunction can be caused by poor connections, broken insulation, or a wire that is broken inside the insulation.
If an intermittent malfunction exists refer to Intermittents and Poor Connections in Wiring Systems.
Test Description
The number(s) below refer to the step number(s) on the diagnostic table.

This step checks for the proper signal voltage.

This step checks for an open in circuit 901.

This step checks for a short to ground in circuit 901.

This step checks for an open in circuit 556.

This step checks for an open in circuit 1056.

1
Was the ABS Diagnostic System Check performed?
--
Go to Step 2
Go to Diagnostic System Check - ABS

2
Are any other DTCs also set as current DTCs?
--
Go to applicable DTC. Go to Diagnostic Trouble Code (DTC) List/Type
Go to Step 3

3
Turn the ignition switch to the OFF position.
Disconnect the EBCM harness connector.
Install the J 39700 Universal Pinout Box using the J 39700-25 cable adapter between the EBCM harness connector and the EBCM.
Turn the ignition switch to the ON position, engine OFF.
Using J 39200 DMM, measure the voltage at terminal 24 of J 39700 .
Is the voltage within the range specified in the values column?
0.20 - 4.80 V
Go to Step 4
Go to Step 5

4
Replace the EBCM. Refer to Electronic Brake Control Module (EBCM) Replacement .

So I've had the EBCM recently repaired, so the next step would be the brake pressure sensor. I think it screws into the EBCM, but what I need to know is can it be purchased seperatly?

 

Im gonna try to get a brake pressure switch headed my way.

Does anyone have any ideas about the 2 PCM codes?
