Pinpoint Test E : AWD Module Power, Ground, Or Internal Fault
- Refer to All Wheel Drive (AWD)
for schematic and connector information.
Normal Operation and Fault Conditions
If the AWD module observes an overpower or a low voltage condition, a DTC is set.

- Vehicle level voltage concern
- AWD module voltage supply
- AWD module ground
- AWD module
- E1 CHECK FOR VOLTAGE DTC IN OTHER MODULES
- Ignition ON.
- Connect the diagnostic scan tool.
- Retrieve continuous memory DTC.
Are voltage DTC set in other modules?
Yes REFER to: Charging System . No GO to E2 - E2 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE GROUND
- Ignition OFF.
- Verify AWD module retaining nuts are secure. Torque: 55 lb. in (6.2 Nm)
Were any of the fasteners loose?
Yes TIGHTEN the AWD module nuts to specification. RETEST the system for normal operation. No GO to E3 - E3 CHECK THE AWD (ALL-WHEEL DRIVE) MODULE POWER FOR VOLTAGE
- Ignition OFF.
- Disconnect the AWD module connector C3841.
- Inspect harness connector for damage. Verify terminals are not splayed, damaged, or pushed out of the connector.
- Ignition ON.
- While manipulating the harness (wiggle test) measure:
Positive Lead Measurement / Action Negative Lead Refer to C3841-1 Ground
Is the voltage greater than 10v and remain constant while wiggle testing the harness?
Yes GO to E4 No REPAIR the circuit. - E4 VERIFY CONCERN IS PRESENT
- Ignition ON.
- Connect the diagnostic scan tool.
- Clear continuous memory DTC.
- Ignition OFF.
- Open and Close Driver's door to initiate module shut down.
- Wait 1 minute for AWD module to sleep.
- Start Engine, allow to idle for 1 minute.
- Retrieve continuous memory DTC.
Did the voltage or internal fault DTC set again?
Yes INSTALL a new AWD module. REFER to: All-Wheel Drive (AWD) Module . No The system is operating correctly at this time. The concern may have been caused by module connections. Address the root cause of any connector or pin issues.
