Use a scanner that communicates with ABS system
You should go to a shop that has and ABS scanner to determine problem. May be wheel sensor or control module ...Alternatively, there may simply be air in the ABS module. If you've opened up the hydraulic lines (say, to replace a brake caliper), then the ABS module has to be purged, or the light stays on. Just open the purge port (not the bleeder valve) on the ABS unit and use the pressure side of a hand-operated vacuum pump (NOT shop air!!) to pressurize the purge port. DON'T use the vacuum side of the pump. Add brake fluid as needed during this process. Do NOT overpressurize. Just use the bleeder valve and hand pump to purge the ABS unit until no more bubbles come out of the bleeder, just brake fluid.
Yes the ecm( engine control module)/ pcm( powertrain control module) are the same thing. Different manufacturers use different acronyms, ECU (engine control unit) is another often used.
Use your thinking.
They used to use cellulose acetate, now they use ABS.
Regarding a model 1997,2 liter sonata, there is not an ignition control module as such. Ignition control comes from the ECM (ELECTRONIC CONTROL UNIT) through the Ignition Power Transistor (often called Igniter) and then to the Ignition coil.I do not have any information on the 1.8 or the 3.0 liter models.
The traction control and the ABS both use the wheel speed sensors in the wheel bearings
Some vehicles do use the engine control module to also control the transmission.
they used a module that carried them back
1995 and earlier models use a separate ESC module mounted near the throttle body of TBI
I use 43auto.com. Their website ahs a parts finder that is pretty good about telling you average price and availability. Good luck.
The Body Control Module contains the Immobiliser. Before towing a vehicle, the Immobiliser should be bypassed. This can be done by removing the Body Control Module. Worst case scenario, use a flat bed to haul instead of tow a vehicle.
