P132C77 — Shutdown path self-test failed
Quick answer
P132C77 indicates that the motor controller's self-test of its high-voltage shutdown path failed repeatedly, so the safety function that isolates the high-voltage system may not work.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
- High-voltage system: do not open or disconnect high-voltage components. Refer the car to a technician qualified for high-voltage work.
Can I still drive?
Have it inspected before further driving. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
