DTC P0581:00 | Cruise control multi-function input circuit high
--- | ---
DETECTION CONDITION | • P0581:00 sets when the cruise control switch circuits are shorted to voltage or open.
POSSIBLE CAUSE | • Clock spring connector or terminals malfunction • Clock spring malfunction • Cruise control switch malfunction • PCM connector or terminals malfunction • Short to power supply in wiring harness between the following terminals: ― Clock spring terminal 2B—PCM terminal 1N ― Clock spring terminal 2C—PCM terminal 1L • Open circuit in wiring harness between the following terminals: ― Clock spring terminal 2B—PCM terminal 1N ― Clock spring terminal 2C—PCM terminal 1L • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY RELATED SERVICE 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.
2 | INSPECT CLOCK SPRING CONNECTOR CONDITION Warning • Handling the air bag system components improperly can accidentally deploy the air bag modules and pre-tensioner seat belts, which may seriously injure you. Read the air bag system service warnings and cautions before handling the air bag system components. (See AIR BAG SYSTEM SERVICE WARNINGS.) (See AIR BAG SYSTEM SERVICE CAUTIONS.) • Turn the ignition switch off. • Disconnect the clock spring connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to Step 8.
No | Go to the next step.
3 | INSPECT CLOCK SPRING • Inspect the clock spring. (See CLOCK SPRING INSPECTION.) • Is there any malfunction? | Yes | Replace the clock spring, then go to Step 8. (See CLOCK SPRING REMOVAL/INSTALLATION.)
No | Go to the next step.
4 | INSPECT CRUISE CONTROL SWITCH • Inspect the cruise control switch. (See CRUISE CONTROL SWITCH INSPECTION [MZI-3.7].) • Is there any malfunction? | Yes | Replace the steering switch, then go to Step 8. (See STEERING SWITCH REMOVAL/INSTALLATION.)
No | Go to the next step.
5 | INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the connector or terminals, then go to Step 8.
No | Go to the next step.
6 | INSPECT CRUISE CONTROL SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY • Clock spring and PCM connectors are disconnected. • Turn the ignition switch to the ON position (engine off). • Measure the voltage between the following terminals (wiring harness-side) and body ground: ― Clock spring terminal 2B ― Clock spring terminal 2C • Is there any voltage? | Yes | Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
No | Go to the next step.
7 | INSPECT CRUISE CONTROL SWITCH CIRCUIT FOR OPEN CIRCUIT • Clock spring and PCM connectors are disconnected. • Turn the ignition switch off. • Inspect for continuity between the following terminals (wiring harness-side): ― Clock spring terminal 2B—PCM terminal 1N ― Clock spring terminal 2C—PCM terminal 1L • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0581:00 HAS BEEN COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Perform the KOEO or KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7].) • Is the same DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
