Troubleshooting
No Audible Tone
When an object is detected while the vehicle's turn signal is active, but the side
object display does not emit an audible tone, either the system is improperly wired
or the side object display has malfunctioned.
1. With the vehicle's ignition switch in the off position, disconnect the display
connector (J1) and use an ohm meter to test the continuity between pin 1
and the turn signal source point.
2. Turn the vehicle's ignition switch to the on position and activate the vehicle's
turn signal, on the same side of the vehicle the side object sensor is located,
and use a volt meter to check for the turn signal voltage between pins 2 and 4.
