Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the rear video display.
2. Ignition ON, test for 100-300 Hz at the control circuit terminal 9.
瀚慖f not within the specified range, test the control circuit for a short to voltage, short to ground, or an open/high resistance. If the circuit
tests normal, replace the radio.
3. If all circuits test normal, replace the rear video display.
