1. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .)
2. Disconnect the ground plate. (For servicing Mazda M Hybrid related parts)
3. Disconnect the connector on the module side and the connector on the part side of the circuit to be inspected.

   If there is continuity: 

   • To specify the malfunctioning location, go to the next step.

   If there is no continuity: 

   • There is no short between circuits, therefore the inspection is completed.
5. Refer to the wiring diagram and verify if there is a common connector between the applicable circuits.

If there is a common connector: 

• Disconnect the common connector and inspect the connector and terminal. (See CONNECTOR INSPECTION .)
• Inspect each common connector for continuity to determine the malfunctioning location.
