G Short-RR Air Spring Solenoid Valve Circuit



Short-Right Rear Air Spring Solenoid Valve Circuit

PINPOINT TEST G: SHORT-RIGHT REAR AIR SPRING SOLENOID VALVE CIRCUIT:






PINPOINT TEST G: SHORT-RIGHT REAR AIR SPRING SOLENOID VALVE CIRCUIT (Continued):






The Control Module has detected a short in the circuit used to activate the right rear solenoid valve. There are five possible causes of this short which are listed below:
1. Battery Positive Voltage (B+) power supply circuit is shorted to ground.
2. Vehicle wiring harness has B+ power supply and ground return circuit to the solenoid valve reversed.
3. Solenoid valve is inoperative.
4. Control Module is inoperative.
5. Right rear solenoid valve has a diode in it. When current is applied in the reverse direction this diode will act like a short. Because all ohmmeters do not have the same positive and negative polarity the following test procedures are used to locate the cause of the short.
