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 • This is a continuous monitor (Other). • MIL does not illuminate. • FREEZE FRAME DATA is not available. • DTCs are stored in PCM memory.
POSSIBLE CAUSE | • Cruise control switch malfunction • Connector or terminal malfunction • Short to power circuit in wiring harness from cruise control switch terminal 2and PCM terminal 3S • Short to ground circuit in wiring harness from cruise control switch terminal 2and PCM terminal 3S • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service information. If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT CRUISE CONTROL SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND • Disconnect the cruise control switch and PCM connectors. • Inspect for continuity between cruise control switch terminal 2 (wiring harness-side) and body ground. • Is there continuity? | Yes | Repair or replace for a 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 ignition switch to the ON position (Engine off). • Inspect the voltage between cruise control switch terminal 2 (wiring harness-side) and body ground. • Is the voltage below 1.0 V? | Yes | Go to the next step.
No | Repair or replace for a short to the power supply, then go to Step 6.
5 | INSPECT CRUISE CONTROL SWITCH OPERATION • Inspect the cruise control switch. (See CRUISE CONTROL SWITCH INSPECTION [L8, LF, L3, L3 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 using cruise control for 2 min. or more. • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
7 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3 Turbo].)
No | Troubleshooting completed.
