Inspection for Short to Ground in Circuit
WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US) .)
- Disconnect the ground plate. (For servicing Mazda M Hybrid related parts)
- Disconnect the connector on the module side and the connector on the part side of the circuit to be inspected.NOTE:
- For the connector disconnection procedure, refer to the removal/installation procedure for each part.
- Inspect for continuity between the applicable terminal of the module-side or part-side connector and body ground.
If there is continuity:
- To specify the malfunctioning location, go to the next step.
If there is no continuity:
- There is no short to ground in the circuit, therefore the inspection is completed.
- 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.
- Repair or replace the vehicle wiring harness which is shorted to ground.
If there is no common connector:
- Repair or replace the vehicle wiring harness.
- Disconnect the common connector and inspect the connector and terminal. (See CONNECTOR INSPECTION .)
