Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Check for related service repair information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to available repair information.
•  If vehicle is not repaired, go to the next step.
No
Go to the next step.
2
INSPECT CRUISE CONTROL SWITCH CONNECTOR FOR POOR CONNECTION
•  Turn the engine switch off.
•  Inspect for poor connection (such as damaged, pulled-out terminals, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal, then go to Step 6.
No
Go to the next step.
3
INSPECT CRUISE CONTROL SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Disconnect cruise control switch and PCM connectors.
•  Inspect for continuity between cruise control switch terminal 6 (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace short to ground, then go to Step 6.
No
Go to the next step.
4
INSPECT CRUISE CONTROL SWITCH SIGNAL CIRCUIT FOR SHORT TO POWER
•  Turn the engine switch to the ON position (Engine off).
•  Inspect the voltage between cruise control switch terminal 6 (wiring harness-side) and body ground.
•  Is the voltage less than 1.0 V?
Yes
Go to the next step.
No
Repair or replace short to power supply, then go to Step 6.
5
INSPECT CRUISE CONTROL SWITCH OPERATION
•  Inspect the cruise control switch.
•  Is the cruise control switch normal?
Yes
Go to the next step.
No
Replace the cruise control switch, then go to the next step.
6
VERIFY TROUBLESHOOTING OF P0564 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Drive the vehicle with cruise control 2 min. or more.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No
Go to the next step.
7
