DTC P2532-772: Ignition Switch Run Position Circuit High: Description

If a hybrid vehicle cannot be turned off, it will not be possible to determine that the vehicle cannot be turned off by listening or looking (high voltage cannot be shut off). In this case, checking for DTCs can help to determine the state of the vehicle.

When the hybrid vehicle control ECU detects that the vehicle cannot be turned off, the ECU will set this DTC. This DTC is set based on communication between the hybrid vehicle control ECU and ECUs that are activated by the IG1 relay and IG2 relay.
