On-Board Diagnostic - Mazda 6 Training Manual

ON-BOARD DIAGNOSTIC

• For easily detecting and locating a malfunction in the cruise control system, a condition detection mode has
been included, as well as an operation mode that can check the operation of switches.
• The on-board diagnostic is essentially carried over from that of the 626 (GF) model, ecept for the following:
— Due to the integration of the control module in the cruise actuator, the circuit between the cruise actuator
and control module is obsolete. As a result, the procedure for the DTC 01 has been changed.
• As the control module is installed in the engine compartment, a waterproof connector is used. As a result, the
terminal voltage measurement method for the control module (in cruise actuator) with the on-board diagnostic
has been changed. For details, see the workshop manual.
