DTC P2530-14: Ignition Switch Run Position Circuit Short to Ground or Open [02/2024 - ]: Description

If a malfunction is detected in the power supply circuit, the No. 2 skid control ECU (brake actuator assembly) power source voltage drops, or there is insufficient voltage to operate the main relay, the No. 2 skid control ECU (brake actuator assembly) will store a DTCs.

If the auxiliary battery voltage is temporarily low, these DTCs may be stored.
