System Fault Indication
If both the red and yellow LEDs remain illuminated continuously after fi ve seconds
of initial power-up, or anytime during normal operation, this is an indication that the
system has detected a failure with the radar sensor or a loss of communications
between the sensor and the side sensor display.
1. Disconnect the sensor and the side object display from the harness and check
the connectors for corrosion, or damage to the harness.
2. Using an ohm meter, check the harness for a short to ground by testing the
resistance from J1 Pin 3 and J2 Pin 3 to chassis ground. This reading should
be greater than 100K ohms or infi nite.
3. Using an ohm meter, check the communications link between the sensor and
the side object display for continuity by testing the resistance from J1 Pin 3 to
J2 Pin 3 (see diagram below). This reading should be less than 0.9 ohms.
