Test H: DTC C1920 - LED #1 Circuit Failure And B2373 - LED #1 Circuit Short To Battery

PINPOINT TEST H: DTC C1920 - LED #1 CIRCUIT FAILURE AND B2373 - LED #1 CIRCUIT SHORT TO BATTERY

Normal Operation
The parking aid system is enabled when the ignition switch is in the RUN position and the transmission is in REVERSE (R). The system can be disabled by the parking aid switch. The parking aid module sends a signal to the LED over circuit CMP02 (GN/BU) when the switch is pressed. The switch and LED are grounded through circuit GD111 (BK/BU).

DTC B2373 (LED Circuit Short to Battery) - sets when the parking aid module senses a short to voltage on circuit CMP02 (GN/BU).

DTC C1920 (LED Circuit Failure) - sets when the parking aid module senses an open or short to ground on circuit CMP02 (GN/BU).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Parking aid switch
