TRANSFER CASE - TOD 5D2-25 Both Speed Sensor Faulty If both the Front and Rear Speed Sensors are faulty continuously for 0.5 seconds the “4WD CHECK” lamp is illuminated. The TOD then responds as follows: 1. If the system is in High Range the TOD sets the EMC Touch off level based on a vehicle speed of 0 and wheel slip control is suspended. 2. If the system is in Low Range, the EMC Duty Cycle is set to maximum until the system is shifted out of 4L. 3. All Electric Shift activity is halted until the Ignition is cycled. If a shift is in progress it will be completed. If both Speed Sensors recover continuously for 0.5 second the TOD will function normally.
The “4WD CHECK” lamp is turned off but the fault code will remain in memory. EMC Test The EMC is tested for open circuit or short circuit to ground. If a fault is detected continuously for 0.8 second the “4WD CHECK” lamp is turned on and all TODTM activity is halted. If the EMC recovers continuously for 0.8 second the TOD will function normally. The “4WD CHECK” lamp is turned off but the fault code will remain in memory. CODING ON TOD Connection of Coding Tool Construct SCANNER into diagnosis connector (20 pins) near fuse box in engine room as below figure. 1. Diagnosis Connector 2. SCANNER Notice:
Coding ; An input activity of data for the proper performance by matching specification, devices and system with control unit. Coding required 1. Replacement of TOD control unit. 2. Adjustment by input error. 3. Change of tire specification. YAD5D150 Coding method 1. Check and record engine type, axle ratio and tire size. 2. Ignition “OFF”. 3. Connect SCANNER with diagnosis connector in engine room. 4. Ignition “ON”. 5. Read the current memorized specification in TOD control unit. SSANGYONG Y200
