DTC P0575: Cruise Control Input Circuit Malfunction

CAUTION
!
• This fault may appear if the wiring harness has been damaged.
Follow the procedure described in "Electrical Circuit Inspection Procedure: in Section 00 in related
manual".
• This check enables the condition and the conformity of the engine wiring harness to be checked.
NOTE
• Conditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
• The cruise control/speed limiter function is inhibited.
• Use service wire for all operations on the ECM connectors.
Detecting Condition
• 1.DEF: Inconsistency of signal
