Hello and welcome to JustAnswer!
The PCM could definitely be the cause of the ETC problem. It may also be a wiring issue, vacuum leak, the MAP sensor, or accelerator pedal position sensor.
When the BAS light is on it's because the ABS module has seen an issue that will affect BAS operation and sets a fault code. This should be unrelated to the ETC; you'd need to determine what codes are setting in the ABS module and go from there.
When the ETC light comes on it's because the PCM has seen an issue that will prevent proper RPM control and has set a fault code. The first step in diagnosing the ETC light will be to see what fault codes are setting in the PCM.
