1997 Pontiac Grand Prix 3800 V6. ABS check
tire press and TRAC off lights codes C1242 rear
esb will not hold motor.
Question: Why does my pontiac have ABS light.
What is rear esb and how do i fix it?
ESB stands for 'expansion spring brake' and it is
internal to the ABS modulator assembly. This
code is because the piston is slipping in the abs
assembly. A common cause for this is that the
motor gear nut has loosened up, and the gear is
slipping, therefore not holding the ESB.
The cover underneath the motor pack can be
removed, and the nuts on the 3 gears checked to
see if one is loose. It is also possible that the
EBCM (electronic brake control module) is faulty.
What needs to be done is have the system
hooked up to a scan tool that can read data and
control abs functions to watch voltage numbers
and decide what is at fault.
Anti-lock brakes are designed to prevent skidding and help
drivers maintain steering control during an emergency stopping
situation. In cars equipped with conventional brakes, the driver
pumps the brakes, whereas in cars equipped with four-wheel
ABS, the driver keeps a firm foot on the brake allowing the
system to rapidly and automatically pump the brakes. Because
the wheels don't lock up, drivers have the ability to steer around
hazards if they are unable to stop in time.
Pontiac grand Prix Tire Pressure And TRAC Lights
1997 Pontiac Grand Prix SE. ABS, Trac off, check engine, tire
pressure. Transmission strainer replaced.
Question I need all the lights off. Please tell me what need to be
done. Cause every car place I take it to tells me they dont deal
with my type of car.
I can't give you an exact diagnosis without knowing what trouble
codes are stored in your car. The trac off and abs light are
probably related, and most likely the cause is a bad wheel speed
sensor or hub bearing.
There can be a wiring harness problem as well if any moisture
has gotten into the harness. The check engine light is on
because you have a problem with one or more sensors on the
engine/drivetrain. Again, would need the exact codes to help you
more. The tire pressure light can be resolved by setting all the
tires to the correct pressure, and then resetting the light.
