Note

After the power switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 90 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
After the power switch is turned off, the navigation receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait at least 60 seconds before disconnecting the cable from the negative (-) auxiliary battery terminal.
When the cable has been disconnected and reconnected to the negative (-) auxiliary battery terminal, open and close the fuel lid before turning the power switch on (IG) (for w/ Canister Pump Module).
Do not replace the spiral cable with sensor sub-assembly with the auxiliary battery connected and the power switch on (IG).
Do not rotate the spiral cable with sensor sub-assembly without the steering wheel assembly installed with the auxiliary battery connected and the power switch on (IG).
Ensure that the steering wheel assembly is installed and aligned straight when inspecting the steering sensor.
