DUAL CLUTCH TRANSMISSION (DCT) (NC700XD/SD)
DTC 54 (OUTER MAINSHAFT SENSOR
SPEED LOW)
• Before starting the inspection, check for loose or
poor contact on the outer mainshaft sensor 3P
(Black) and PCM 33P connectors, and recheck the
DTC.
• If the PCM is replaced, perform the following:
– Key Registration Procedure (page 23-6)
– Clutch Initialize Learning Procedure (page 12-120)
1. Outer Mainshaft Sensor Input Voltage
Inspection
Turn the ignition switch OFF.
Disconnect the outer mainshaft sensor 3P (Black)
connector.
Turn the ignition switch ON with the engine stop
switch " ".
Measure the voltage between the wire harness side
outer mainshaft sensor 3P (Black) connector [1]
terminals.
Is there about battery voltage?
YES – GO TO STEP 2.
NO – GO TO STEP 3.
2. Outer Mainshaft Sensor Output Line Inspection
Measure the voltage between the wire harness side
outer mainshaft sensor 3P (Black) connector [1]
terminal and ground.
Is the voltage within 4.75 – 5.25 V?
YES – GO TO STEP 7.
NO – GO TO STEP 5.
3. Outer Mainshaft Sensor Input Line Open Circuit
Inspection
Connect the ECM test harness to the PCM
connectors (page 4-14).
Check for continuity between the wire harness side
outer mainshaft sensor 3P (Black) connector [1] and
test harness [2] terminals.
Is there continuity?
YES – GO TO STEP 4.
NO – Open circuit in the White/blue wire
Connection: White/blue (+) – Green/yellow (–)
Connection: Pink/yellow (+) – Ground (–)
Connection: White/blue – A25
