id0102f1808900

DTC P0564 | Cruise control switch circuit malfunction
--- | ---
DETECTION CONDITION | • The PCM monitors the cruise control switch signal. If the PCM detects that any one of following switches (Main, CANCEL, SET/COAST, RESUME/ACCEL) remains on for 2 min, the PCM determines that the cruise control switch circuit has a malfunction. Diagnostic support note • The MIL does not comes on. • PENDING CODE is available if PCM detects the above malfunction condition. • FREEZE FRAME DATA is not available. • DTC is stored in PCM memory.
POSSIBLE CAUSE | • Cruise control switch malfunction • Connector or terminal malfunction • Short to power circuit in wiring from cruise control switch terminal B and PCM terminal 102 • Short to ground circuit in wiring from cruise control switch terminal B and PCM terminal 102 • PCM malfunction

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 CONTOROL 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 B (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 B (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. (See CRUISE CONTROL SWITCH INSPECTION [MZR-CD (RF Turbo)].) • 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 WDS or equivalent. • 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 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
