DR-15A 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. Voltmeter should be pulsating between 0 and 14 volts.
3. If voltmeter does not pulsate and indicates within one volt of battery voltage, proceed to Test 15 step B.
4. If voltmeter pulsates between 0 and 3 volts, replace solenoid.
5. If voltmeter does not pulsate and indicates zero to one volt, disconnect logic module red connector. If voltage if now within one volt of battery voltage, replace logic module. If not, locate and repair short to ground in blue wire.
