DUAL CLUTCH TRANSMISSION (DCT) (CRF1000D)
SERVICE INFORMATION
DUAL CLUTCH TRANSMISSION (DCT) (CRF1000D)
GENERAL
• This section covers service of the electrical and mechanical systems of the Dual Clutch Transmission (DCT).
• A faulty DCT system is often related to poorly connected or corroded connectors. Check those connections before proceeding.
• Read the "DCT Troubleshooting Information" carefully, and inspect and troubleshoot the DCT system according to the DTC.
Observe each step of the procedures one by one. Note the DTC and probable faulty part before starting diagnosis and
troubleshooting.
• The PCM may be damaged if dropped. Also, if a connector is disconnected when current is flowing, the excessive voltage may
damage the PCM. Always turn off the ignition switch before servicing.
• If the PCM is replaced, perform the following procedure.
– Key Registration Procedure (page 23-3)
– Clutch Initialize Learning Procedure (CRF1000D) (page 13-82)
• The drive mode AT or MT are changed electrically with the A/M switch.
• Be sure to use the recommended tires, and the specified drive and driven sprocket to operate the dual clutch transmission
system normally.
• For VS sensor service (page 4-42).
• For oil pump service (page 9-7).
• The following color codes are used throughout this section.
Bl = Black Bu = Blue
Br = Brown G = Green

For DCT System Troubleshooting

• The DCT system is controlled by the PCM. Therefore, some detection items are shared in the PGM-FI and DCT systems, and
they may affect the operation of both systems.
• Before starting any troubleshooting, check the following items and refer to the appropriate troubleshooting.
– MIL blinks or DTC for the PGM-FI system (page 4-6).
– Shift indicator blinks or DTC for the DCT system (page 13-7)
– Symptom of the DCT system operation (page 13-3)
– TXD line (page 22-14)
• Refer to the "PGM-FI Troubleshooting Information" for the "CIRCUIT INSPECTION" information (page 4-7).
• The gearshift mechanism included the following items. If the gearshift mechanism is faulty, refer to each component service.
– Shift control motor/reduction gears (page 13-71)
– Gearshift linkage (page 13-74)
– Shift drum/shift fork (page 14-15)

Shift Control Motor Function Procedures

• If the PCM has a DTC, the function test does not work.
• The function test is not for the quality check of the shift control motor.
Conduct a test of the shift control motor when the following items have been serviced or replaced.
– Shift control motor
– Reduction gears
– TR sensor
– Shift spindle angle sensor
Connect the MCS (page 4-6), and perform the shift control motor function test.

Linear Solenoid Valve Function Procedures

• If the PCM has a DTC, the function test does not work.
• The function test is not for the quality check of the linear solenoid valve.
• Do not open the throttle while testing the linear solenoid valve function.
Conduct a test of the linear solenoid valves when the linear solenoid valves have been serviced or replaced.
Connect the MCS (page 4-6), and perform the linear solenoid valve function test.
