Flashin low traction and abs light - 2003 Isuzu Ascender

TAKE CAR TO A GARAGE OR DEALERSHIP HAVE THE ABS BRAKES AND TRACTION CONTROL CODE SCAN.YOUR ABS BRAKE SYSTEM WILL COME ON ADJUSTING BRAKE PRESSURE TO AVOID A SKID.THAT WHY LOW TRAC LIGHT COMES ON. MOST OF THE TIME WHEN YOU SEE LOW TRAC LIGHT DRIVING ON DRY ROADS PROBLEM IS IN THE ABS BRAKE UNIT OR BAD WHEEL SPEED SENSOR.

The brake light may be on because of low fluid.The traction control is on because the abs light is on.System requires the abs to be actively working for traction control to work.The most common cause of this is a wheel speed sensor which on this vehicle is part of the bearing hub assembly.You will need a scan tool to locate where the fault is in the abs system.

means the traction control module is bad. That light is suppose to come on when you lose traction to let you know the traction control is kicking in.

chek the brake fliud level. if low light will set light and abs wont work.

If your ABS light is on as well, have a shop scan it (it requires a special scanner). If it's just your Trac light without ABS, it is most likely a sensor under the hood at fault. If you are getting a check engine light as well, get the codes read!
This happened to me without an ABS light and it was the upstream O2 sensor. The reason it throws the Trac light is because if any components that the traction control uses (ignition, fuel) are affected by a bad sensor, the PCM shuts down traction.
In fact, when I replaced the O2 sensor, a handful of other little issues resolved as well.
If you do have an ABS light on, it could very well be a wheel speed sensor.

These problems do not seem to be related at all. The cause of the warm ac air could be several things from a low refrigerant charge to a plugged condensor fins to the compressor clutch not kicking in. You just have to follow a systematic approach when diagnosing these problems.

Have the ABS system scanned for codes. The ABS and Traction control use the same computer. You likely have a bad wheel speed sensor.

The red brake light is the key here. That usually indicateds a hydraulic problem. Check you fluid level in master cylinder and see if it is low. Also the level indicator sensor there in the master cylinder maybe sticking or corrioded. If ABS sees the red brake light it will shut off and turn on the ABS light,also traction control would be disabled as well.

Ok, check the brake fluid level for a start. This could mean a few things. Your brake pads might be worn down, which would bring a yellow warning light on(triangle), at the same time with the pads being low it will have displaced the fluid, making the level low, this would be a red light on. Now because of this the body control module has detected these faults, will have turned the abs off, hence the abs light.
If brake fluid is low, this could confirm my theory.
If its low, top up with dot 5 brake fluid and take to garage to have new pads fitted.
