DESCRIPTION
This DTC is output when serial communication signals and LIN communication signals in the circuit
between the main body ECU and steering lock actuator (steering lock ECU) are inconsistent.
HINT:
When the main body ECU is replaced with a new one and the negative (-) battery terminal is connected,
the power source mode becomes the IG-ON mode. When the battery is removed and reinstalled, the
power source mode that was selected when the battery was removed is restored.
After the main body ECU or steering lock ECU is replaced, perform the registration procedures for the
engine immobiliser system (See page EI-8).
