circuit
Defective position sensor in motor
Stuck in 4L mode
• Check communication line.
• Replace TCCU if necessary.
• When the mode switch is defective
• Check TCCU pin No.4 and 16.
• Mode change
- 2H (Pin No. 4: Ground)
- 4H (No contact: Open)
- 4L (Pin No.16: Ground)
• Voltage at TCCU pin No.11: 11 ~ 15 V
• EMC resistance: 2.5
Ω
• Check the relevant connectors for contact.
• Replace TCCU if necessary.
• When the hub control circuit is open or short to ground over
0.2 second
• Replace TCCU if necessary.
• When TCCU detects the motor failure for 1 second
• Check the relevant harnesses for contact.
• Replace TCCU if necessary.
• When TCCU detects the motor failure for 1 second
• Check the relevant harnesses for contact.
• Replace TCCU if necessary.
• 2H-4H: after 1.5 seconds
• 4H-4L: after 3 seconds
• Check the relevant harnesses for contact.
• Replace TCCU if necessary.
• When no shifting operation from 4L to 4H, even though the
shift conditions are satisfied and no error.
• Replace TCCU if necessary.
