I'm finishing up my EAS conversion with the only issue remaining is an 'Exhaust valve stuck closed' message. While researching possible causes I found this thread that matches my issue exactly.Testing the solenoids is easy.
The EAS ECU simply switches each of these from 0V to 12V to trigger the valves. The driver pack then converts these 0-12v signals to the modulated pulses for the solenoids.
- Unplug the multiplug at the front of the EAS box.
- Connect the 12V & GND pins to the car battery
- Pins 12+13 are 12V
- Pins 10+11 are Gnd
- Connect each pin 1 to 6 in turn to 12V
- 1-4 are the corner valves
- 5-6 are Inlet & Exhaust
Read the EAS System Info document for full description. It's a 1.2MB PDF that I cannot attached in this forum, but I did upload it to Landyzone.
So pins 12+13 should have wires run directly to the positive connector on the battery. Pins 10+11 should have wires run directly to the negative connector on the battery. To then test a solenoid, let's take pin 1 as an example which is the rear left valve. To test it I would connect a wire to pin 1 and the other end of the wire to what? The pos terminal on the battery?
