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.
