NO
     
     
     
Repair an open in the GND wire between clutch pedal position switch B and G304, then do the repair verification.
5.
Open wire check (CRUISE SW (CRUISE) line):

Open wire check (CLUTCH SW (CRUISE) line)
?1.
Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

?2.
Jump the SCS line with the HDS.


?3.
Disconnect the following connector.

?4.
Check for continuity between test points 1 and 2.
Test condition
IG LOCK (0) or OFF mode
Clutch pedal position switch B (3P): disconnected
PCM connector A (51P): disconnected
Test circuit
CLUTCH SW (CRUISE)
Test point 1
PCM connector A (51P) No. 50 (PNK)
Test point 2
Body ground


Is there continuity?

     
YES
     
     
     
The CLUTCH SW (CRUISE) wire is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then do the repair verification.
     
NO
     
     
     
Repair an open in the CLUTCH SW (CRUISE) wire between clutch pedal position switch B and the PCM (A50), then do the repair verification.
Repair verification:

?1.
Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

?2.
Reconnect all connectors.

?3.
Exit the SCS mode with the HDS.


?4.
Turn the ignition switch to ON (II).

?5.
Clear the DTC with the HDS.
