DR-17A Fault Code 37 BARO Read Solenoid Circuit

1. Connect diagnostic read-out tool to engine test connector.
2. Connect a voltmeter between blue wire of baro read solenoid connector and ground, then enter system into ATM Test Mode Code 10. If voltmeter reading is cycling and solenoid is clicking, check circuit for poor connection.
3. If voltmeter does not pulsate and indicates within 1 volt of battery voltage, proceed to Test 17 step B.
4. If voltmeter pulsates between 0 and 3 volts, proceed to Test 17 step C.
5. If voltmeter does not pulsate and indicates 0 to 1 volt, disconnect logic module red connector. If voltage if now within 1 volt of battery voltage, replace logic module. If not, proceed to Test 17 step C.
