锟斤拷If the voltage is less than the specified range, test the affected circuit for a short to ground, an open/high resistance or short to voltage. If
all circuits and connections test normal, TCCM for proper operation.
4. Using the PU probes J 35616-4A, test for 7.50-8.50 V between the incremental encoder sensor (8 V) supply circuit, TCEM X1 pin G and the
low reference circuit, TCEM X1 pin H.
锟斤拷If the voltage is greater than the specified range, test the low reference circuit for a short to voltage. If all circuits and connections test
normal, test the TCCM for proper operation.
锟斤拷If the voltage is less than the specified range, test the low reference circuit for a short to ground, an open/high resistance or short to
voltage. If all circuits and connections test normal, test the TCCM for proper operation.
5. Using the PU probe J 35616-4A, test for 6.0-7.0 V between the incremental encoder impulse signal circuit, TCEM X1 pin E and a good
ground.
锟斤拷If the voltage is greater than the specified range, test the affected circuit for a short to voltage. If all circuits and connections test normal,
test the TCCM for proper operation.
锟斤拷If the voltage is less than the specified range, test the affected circuit for a short to ground, an open/high resistance or short to voltage. If
all circuits and connections test normal, test the TCCM for proper operation.

all circuits and connections test normal, test the TCCM for proper operation.
7. Using the PU probe J 35616-4A, test for greater than 500 ohm between the incremental encoder sensor (8 V) supply circuit, TCEM X1 pin G
and all other pins of the TCEM X1.
锟斤拷If the resistance is less than the specified range, test the affected circuits for a shorted together condition. If all circuits and connections
test normal, test the TCCM for proper operation.

all other pins of the TCEM X1.
锟斤拷If the resistance is less than the specified range, test the affected circuits for a shorted together condition. If all circuits and connections
test normal, test the TCCM for proper operation.
9. Using the PU probe J 35616-4A, test for greater than 10 ohm between the incremental encoder direction signal circuit, TCEM X1 pin F and
all other pins of the TCEM X1.
锟斤拷If the resistance is less than the specified range, test the affected circuits for a shorted together condition. If all circuits and connections
test normal, test the TCCM for proper operation.

Component Testing
Incremental Position Sensor
1. Set parking brake.
2. Block wheels.
3. Remove the encoder motor from transfer case. Using a paint pen or marker, place indexing marks on the shift detent lever receiver and the
mounting surface of the encoder motor.
4. Connect encoder motor to engine harness.
5. Key ON, engine OFF.
6. Transmission in Neutral.
7. Attach scan tool. Clear codes. DTC C0569-4B may remain in memory.
Note: You must perform the Transfer Case High/Low Clutch Reset (See: Transmission and Drivetrain/Transfer Case/Testing and
Inspection/Symptom Related Diagnostic Procedures/MP 3010-NP0/Transfer Case High/Low Clutch Reset) procedure after performing the
next step.
8. Monitor the following parameters while using the Transfer Case Motor Control function of the Special Function feature of the scan tool to
