Transfer Case. Each rotation of the front propshaft will result in 30 speed sensor pulse.
EMC An Electromagnetic clutch used to control the amount of torque applied to the front propshaft.

front propshaft.
High Range The highest (numerically lowest = 1 :1) gear ratio between the input and outputsof the Transfer Case.
Low Range The lowest (numerically highest = 2.48:1) gear ratio between the input and outputs
of the Transfer Case.
4H/4L Switch A switch which selects the desired gear ratio.
Shift Motor Electric motor which changes the Transfer Case range.
Position Encoder A set of 4 Gray code switches which provide feedback to the TCCU indicating theposition of the Shift Motor.
Clutch Interlock Switch A switch on vehicles equipped with a manual transmission which indicates that the clutch pedal is depressed.
Neutral Safety Switch A switch on vehicles equipped with an automatic transmission which indicatesthat the transmission is in neutral.
Shift Inhibit Speed The vehicle speed above which Transfer Case shifts are disallowed. Vehicle speedis indicated by propshaft speed measurement.

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.

8B-8 SUPPLEMENTAL RESTRAINT SYSTEM(SRS) Energy Reserve System Energy reserve system is consisted of condensor and energy switch and will check following items continuously during system operation.
- High voltage
- Low voltage
- Low rating capacity
- Function of the energy reserve switchIf there is fault in the energy reserve system, warning lamp will turn on. And defects are found by continuouschecking of the condenser voltage, the system will enter overall shutdown status for safety reason. Shutdown Switch There is 1 energy shutdown switch in the system and it will be checked during start-up. And it also checks that
condenser is discharging properly. If shutdown switch is short, it will be detected during condensor voltage test. If squib line fault is obvious, the warning lamp will turn on and the module will enter overall shutdown status. Accelerometer Check Accelerometer function will be checked during start-up. During operation, accelerometer off-set signal will be checked, If there is fault, module will enter overall shutdown status. ASIC Overheat
Module monitors upper side ASIC overheats continuously. If overheated, the module will enter overall shutdown status. Microprocessor Fault Module checks EEPROM, ROM checksum and RAM during start-up. EEPROM tests checksum operation.If RAM or ROM checksum is defective, module will not allow start-up continuously but will be re-set,If EEPROM is defective, warning lamp will turn on and the module will enter overall shutdown status.During operation, RAM will continuously verify the proper operation of temporary memory program data usage. If there is fault, the module will enter overall shutdown status and the warning lamp will turn on.
Watchdog Test
Watchdog function will be tested in start-up. If there is fault during the test, warning lamp will turn on and the module will enter overall shutdown status.
