DESCRIPTION
This DTC is output when there is a problem in the IG2D output circuit, which is from the inside of the main
body ECU to the IG2 relay.
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 is replaced, perform the registration procedures for the engine immobiliser
system (See page
EI-8
).
