Symptom: AWD Will Not Engage
1. Check the gearcase coil resistance. To test the gearcase coil resistance, use the coil harness (Grey & Brown/
White).
NOTICE
To test the gearcase coil resistance, use the coil harness. The gearcase coil should measure between 22.8 ohms and
25.2 ohms.
ADC Front Gearcase Coil Resistance
B-C (4X4): 23 Ω ±4Ω
A–D (4X4 ADC): 12.49 Ω ±4Ω
2. Check the minimum battery voltage at the Grey & Brown/White wires that feed the hub coil wires.
AWD Coil Applied Battery Voltage:
11.80-12.0 Vdc
3. Inspect the armature plate
e
for a consistent wear pattern. There should be two distinct wear bands
r
(one band
inside the other). If only one band of wear is present (or if there is wear between the two bands, inspect the coil
area as indicated in Step 4. A band with an interrupted wear mark may indicate a warped plate, which may cause
intermittent operation.
