DTC code C1226

ABS code not check engine light code .
DTC C0201 00: Antilock Brake System (ABS) Enable Relay Contact Circuit
The solenoid relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids.
Circuit/System Verification
With scan tool installed, clear the DTCs then drive the vehicle in a straight line at a speed greater than 20 km/h (13 mph). If the DTC did not set as a current DTC see diagnostic aids.
Circuit/System Testing
Test for an open or a short to ground in the battery positive voltage circuit to the EBCM. Verify no open or a short to ground is found.
Test the EBCM ground circuit, an open or high resistance.
? If an open or a short to ground is found, repair the circuit.
Replace the EBCM assembly.

DTC C0201 (Equal to or over 8600 GVW)
The system relay, located within the electronic brake control module (EBCM), supplies battery voltage to all of the valve solenoids and to the Antilock Brake System (ABS) pump motor. When the relay contacts close, the EBCM monitors the voltage supplied to the valve solenoids and compares this voltage to monitored ignition voltage.
Action Taken When the DTC Sets
• The EBCM disables the ABS/DRP.
• The ABS indicator turns ON.
• The brake warning indicator turns ON

C1226, brake lamp indicator short circuit.

C1214, ABS inlet valve coil failure

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

Have the codes checked ! Do you know what codes are ,What the light is for ? The light is to warn the driver that there is a problem in the ABS system . Have the codes checked before replacing parts ,the code will point you in the direction to go .This system can set numerous DTC'S

DTC C1221 LF Wheel Speed Sensor Input Signal is 0
C1222 RF Wheel Speed Sensor Input Signal is 0
DTC C1226 RF Excessive Wheel Speed Variation
DTC C1232 LF Wheel Speed Circuit Open or Shorted
DTC C1233 RF Wheel Speed Circuit Open or Shorted
DTC C1291 Open Brake Lamp Switch Contacts During Deceleration
DTC C1291 detects an open brake switch. The EBCM looks for deceleration rates that may indicate braking action. The EBCM verifies braking action by repeating the method for finding deceleration rates that indicate braking action several times. In each case, the ABS will not be available because the EBCM does not see the brake switch input.
DTC P1106 Manifold Absolute Pressure (MAP) Sensor Circuit Intermittent High Voltage
DTC P1887 TCC Release Switch Circuit (3.4L)
DTC P1887 TCC Release Switch Circuit (2.4L)
The torque converter clutch (TCC) release switch is part of the automatic transmission fluid pressure (TFP) manual valve position switch. The TFP manual valve position switch is mounted to the transmission valve body. The TCC release switch is normally-closed.
The switch signals the PCM that the TCC is released. This is accomplished by torque converter release fluid pressure acting on the switch contact, thus opening the switch. When the voltage is high on the circuit, the PCM recognizes that the TCC is no longer engaged.
When the PCM determines that the TCC release switch is open (indicating that the TCC is not applied) and the TCC slip speed indicates that the TCC is applied, then DTC P1887 sets. DTC P1887 is a type B DTC.
You have all kind of problems , I suggest you take this to a qualified ASE certified repair shop that has the diagnostic tools to trouble shoot an repair the vehicle . Electrical testing is a must with open circuits an shorts ,plus hooking up a scan tool that reads sensor data .Not just a code reader like at the parts store . This video he has a Chrysler vehicle ,doesn't matter . Test is the same for all make an models !

How to test digital ABS wheel speed sensor

Take your battery cables off for 10 minutes and hook them back up. This will reset the computer and clear the codes. If it stays popped up, the bulb for the abs system in your dash cluster is burnt out.

C1226 Right Front Excessive Wheel Speed Variation, and C1233 Right Front Wheel Speed Circuit Open or Shorted.
Have you replaced the wheel bearing on the right front? the sensor may well be bad, look first at the wiring however, as a bad connection will produce these codes. road salt, road debris, etc can lead to wiring damage. if no damage, I would have the sensor checked for a proper reading, if its out of range, then replace the wheel bearing (or sensor if its replaceable separately, you didn't give a year) if it checks out OK then move to the wiring to the ABS computer, then the computer itself.

looks like all 4 brakes need checked..

ABS on ? DTC'S - diagnostic trouble code's are probably stored in the ABS control module . 4X4 an ABS are not related . To fix , take it to a qualified repair shop.
SERVICE 4WD: Refer to Transfer Case Circuit Description in

Transfer Case Shift Control Module
The transfer case shift control module uses the VIN information for calculations that are required for the different calibrations used based on axle ratio, transmission, tire size, and engine. The system does not know which calibration to use without this information. The transfer case shift control module monitors the speed of the front and rear propshafts in order to detect wheel slippage. When wheel slippage is detected, the module applies a clutch pack contained in side the transfer case. This clutch pack is used to lock-in and apply the front propshaft, transferring torque to the front wheels. The clutch pack is applied by a motor/encoder assembly. When slip is no longer detected by the transfer case shift control module, the clutch is no longer applied.

These are all code's for 4X4 Do you know what a DTC is ? diagnostic trouble code

The traction control and abs are both activated by the abs sensors located at all four wheels. It is common for those sensors to get covered in brake dust and get false or no signal. Also the wiring connections can become corroded over time. I am not sure what the codes are for but checking the sensors/wiring are where I would start.
