DETERMINING SHORT TO POWER SUPPLY LOCATION (CAN-BUS No.6) [R.H.D.]

• When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.

• When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.

• Disconnect the negative lead-acid battery terminal before performing any work that requires handling of connectors.
