Detective CAN commuication

Defective mode switch

Open or short to ground in magnetic
clutch coil circuit

Open or short to ground in hub
control circuit

Open to ground in shift motor circuit

Short to ground in shift motor output
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.
