What does this fault code mean?

One of the transmission's three power stages, power stage 2, is not working correctly. The power stage controls the solenoids CSMS1, CSPS1 and CCFS in the transmission. The control module detects the fault by comparing output current and voltage with the fed-back values. The fault is caused by a damaged power stage or a damaged control module.

Possible causes

Damaged power stage
Damaged transmission control module (TCM)

What you can do

1Read the fault codes in the central electronic module (CEM). If any of them can cause too little voltage reaching the transmission control module, fix that first
2Check the connectors and wiring between the transmission control module and the CEM for oxidation and open circuits with a multimeter
3Clear TCM-0530 and drive the car to see whether it comes back
4Have a workshop check the power stage with diagnostic equipment. If the control module is faulty, a workshop must replace it
