DR-4 Fault Code 16 Battery Sensing Circuit
1. Place ignition switch in Off position, then disconnect logic module blue electrical connector.
2. Connect voltmeter between logic module blue electrical connector terminal No. 22 and ground.
3. If voltmeter reading is within 1 volt of battery voltage, replace logic module.
CAUTION: Before replacing the logic module, make sure the terminal in cavity No. 22 is not crushed so that it cannot touch the logic module pin.
4. If voltmeter reading indicates no voltage, check wiring from terminal No. 22 of logic module blue electrical connector for an open circuit.
