DR-13A Fault Code 37 BARO Read Solenoid Circuit

1. Connect diagnostic read-out tool to engine harness connector.
2. Connect a voltmeter between light blue wire of baro read solenoid connector and ground, then enter system into ATM Test Mode Code 10.
3. If voltmeter does not pulsate and indicates within one volt of battery voltage, proceed to Test 13 step B. DR-13B BARO Read Solenoid Control Wire
4. If voltmeter pulsates between zero and five volts, proceed to Test 13 step C. DR-13C BARO Read Solenoid Windings For an Open Circuit
5. If voltmeter does not pulsate and indicates zero to one volt, disconnect logic module blue connector. If voltage if now within one volt of battery voltage, replace logic module. If not, locate and repair short to ground in light blue wire.
