ABS and brake warning light stay on, A/C inop. A/C system good

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

The problem for engine overheating rise due to insufficient refrigerant. Try recharging the refrigerant tank with fresh refrigerant and water. If the refrigerant in the tank is of poor quality then also engine overheat.

The reason for ABS light to come may be due to air in the brake fluid line. Try brake bleeding to remove the air bubbles. Also the faulty brake actuator line may cause the problem. Check for actuators on each wheel.

Pollution warning light comes on if the exhaust system not works properly. Check for faulty Oxygen sensor or faulty catalytic convertor.

These details will help.

Thanks.

The brake and ABS lights could be on because of a brake or ABS problem. The ABS system uses the hydraulic brake system in addition to the ABS components.
The high idle could be a vac leak or a problem with the idle air control valve. You could check the computer for trouble codes even if the warning light does not stay on.

The warning lights mean there should be a trouble code stored in the body computer. I would start there.
When the ABS system is inop it may prevent the cruise from working too. Sometimes a hydraulic brake system failure will turn the ABS light on too. After repairs you would need to scan the system to turn the light off with most vehicles.
Are the brake lights in the rear of the truck staying on ?

HAVE CAR ABS BRAKES CODE SCAN.BECAUSE WHEN ABS LIGHT IS ON.YOUR CAR ABS BRAKES NOT WORKING.CHECK ABS BRAKES FUSE AND RELAYS.IF ALL IS GOOD.HAVE DEALERSHIP OR GARAGE CHECK ABS BRAKE SYSTEM BECAUSE ABS BRAKE UNIT IS PART OF THE BRAKE MASTER CYLINDER IF KEEP DRIVING COULD END UP WITH BRAKE FAILURE.CAR NOT SAFE TO DRIVE WHEN ABS OR ANY WARNING BRAKE LIGHT APPEARS.

MOST OF THE TIME WHEN TRAC LIGHT AND ABS BRAKE LIGHT COMES ON YOU A HAVE A PROBLEM IN THE ABS AND TRAC SYSTEM.THIS IS A DEALERSHIP FIX. YOU CAN CHECK ABS BRAKE FUSES MAKE SURE IT IS IN TIGHT.AND CHECK FOR FAULTY ABS RELAYS.TO CHECK RELAY LOOK AT RELAY TERMINALS YOU HAVE TERMINAL 86 AND TERMINAL 85.YOU CONNECT TERMINAL 85 TO GROUND AND TERMINAL 86 TO BATTERY POSITIVE TERMINAL.IF RELAY CLICKS WHEN BATTERY VOLTAGE IS APPLIED.RELAY IS WORKING IF YOU HEAR NO CLICK RELAY NO GOOD NEEDS REPLACING.

Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the car

abs relay some times go bad

The brakes will feel fine until u need the ABS, when the light is on the ABS is disabled. You need to have the ABS system tested for trouble codes, if the light is on there will be a code or codes.
