4. Electric Shift Default ModeIf the motor fails to reach its destination, the TCCU will attempt the following (in order):
a. The TCCU will wait 3 seconds then attempt the shift again.
b. If the second attempt to reach the destination fails the TCCU will wait 3 seconds then attempt to rotate the motor back to the original position. If successful, all future shifts will be inhibited until the Ignition is cycled.
c. If the attempt to return to the original position fails, the TCCU will wait 3 seconds then attempt to rotate the motor to the original position again. If the second attempt to return to the original position is successful, the “4WD CHECK ” lamp will be illuminated, and all future shifts will be inhibited until the Ignition is cycled.
d. If the second attempt to return to the original position fails the motor will be turned off, the “4WD CHECK ” lamp
will be illuminated, and all future shifts will be inhibited until the Ignition is cycled.
TOD TM
System Operation
The TOD TM
System is responsible for distributing torque between the front and rear axles. The TCCU monitors the
propshaft speeds, operating range (High/Low), and ABS activity and then applies a calculated amount of torque tothe front axle by Pulse Width Modulating the current applied to the EMC.
1. Touch-off Torque
The minimum EMC Duty Cycle is based on the vehicle speed and throttle positionThe TCCU receives the TPS signal from the following sources:On vehicles equipped with CAN, the TCCU receives the TPS signal from the CAN bus.
2. When Slip Detection
The TCCU continuously monitors the front and rear propshaft speeds to detect wheel slip.
3. Wheel Slip Control When wheel slip is detected the TCCU controls the EMC duty cycle as necessary until the wheel slip is reduced
below the allowable limit. The EMC Duty Cycle will then be reduced to the Touch-Off value.
4. Brake/ABS Strategy When the ABS System is active, the EMC Duty Cycle is set to a fixed duty cycle (30%) to aid in braking without counteracting the ABS System.
5. 4L Strategy When the system is operating in 4L, the TCCU continues TOD TM
(operation provided that the propshaft speed is
below 175 rpm (5220 pulses/minute)). When the speed increases above 175 rpm, the EMC Duty Cycle is set tothe maximum value (88%) which applies the maximum available torque to the front axle.

19. Install wave spring, insulator washer and armature. (Threeoffset slots must align with housing to be installed) NoticeThree slots on the thrust washer must be aligned with the three tabs on the clutch pack housing.
20. Install apply cam onto the rear output shaft, install three balls into the apply cam, install cam and coil housing assembly onto rear output shaft. Install thrust bearing assembly onto output shaft.
21. If removed, drive the front output shaft ball bearing into
the rear cover bore with Front Shaft Needle Bearing Replacer and Driver Handle.
22. If removed, install the rear output bearing in the rear case bore. Drive the bearing into the rear case bore with OutputShaft Bearing Replacer and Driver Handle. Make sure thatthe bearing is not cocked in the bore. Install the internalsnap ring that retains the bearing to the rear case.
23. Install the clutch coil from inside the rear case until the wire and studs extend through the cover. Install the washersand nuts and tighten. CAUTIONDo not kink or trap the wire while seating the clutch coil to the case.
24. Slide the spring spacer on the camshaft and position it beneath the drive tang. Place the torsion spring on thecamshaft. Position the first spring tang to the left of thecamshaft drive tang(View A). Wind the second spring tang clockwise past the drive tang(View B). Push the torsion spring and sleeve in as far as it will go (View C). This willseat the second spring tang on the right side of the drivetang. Install the helical cam and slide the drive tang betweenthe torsion spring tangs as far as it will go.
