DTC C1778 Power Steering Failure
— The power steering assembly has a fault line
that it uses to notify the interface adapter
assembly (IAA) module when a power
steering system fault occurs. The power
steering assembly outputs a 12-volt signal over
the fault line when there is no fault and pulls
it low (0 volts) when it detects a fault. The
IAA module generates DTC C1778 if it
detects the power steering fault line is low for
more than 30 seconds with the power steering
assembly enabled. The signal stays low until
the concern has been corrected.
