Test DN: Step 10

10) Code 84: Check EVR Solenoid Resistance  Code 84 indicates a fault in the EVR solenoid circuit. Possible causes for this fault are a faulty EVR solenoid or, shorted or open harness. Turn key off and wait 10 seconds. Set DVOM on 200-ohm scale. Disconnect EVR solenoid connector and measure solenoid resistance.

EVR SOLENOID RESISTANCE

Application Resistance
4.9L & 5.8L (under 8500 lbs. GVW) 20-45 ohms
7.5L 100-135 ohms
All Others 30-70 ohms

If reading is not within specification, replace EVR solenoid assembly and repeat QUICK TEST. If reading is within specification, go to next step.
