P0585-SPEED CONTROL SWITCH 1/2 CORRELATION
For a complete wiring diagram, refer to the Wiring Information.
 |
Theory of Operation
The Speed Control Switches are located in the Right Steering Wheel Switch. The Right Steering Wheel Switch is hardwired to the Powertrain Control Module (PCM) via the clockspring pass-through within the Steering Column Control Module (SCCM). The SCCM is located near the top of the steering column below the steering wheel. The SCCM includes the steering column shroud, the Steering Angle Sensor (SAS), the Clockspring, the Multi-function Switch, a Steering Column Power Tilt and Telescope Switch (if equipped), and a trim cover.
-
When Monitored:
Continuously with the ignition on.
-
Set Condition:
The Powertrain Control Module (PCM) has detected that a non-permissable combination has occurred in the Speed Control Switch.
Possible Causes |
|---|
| S/C SIGNAL 1 AND S/C SIGNAL 2 CIRCUITS |
| SPEED CONTROL SWITCH (RIGHT STEERING WHEEL SWITCH) |
| CLOCKSPRING |
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
Turn the ignition off disconnect
the 12-volt battery and wait two minutes before proceeding. Failure
to follow these instructions may result in possible serious or fatal
injury.
WARNING:
Do not place an intact non-deployed
airbag face down on a hard surface, the airbag propels into the air
if accidentally deployed. Failure to follow these instructions may
result in possible serious or fatal injury.
WARNING:
| 1. | Turn the ignition on. |
| 2. | With the scan tool, read DTCs |
Does the scan tool display this DTC as active?
Yes
- Go To 2.
No
- Perform the INTERMITTENT CONDITION diagnostic procedure (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
2. RIGHT STEERING WHEEL SWITCH
| NOTE: | Visually and physically inspect the wiring harness between the Right Steering Wheel Switch harness connector and the SCM C6 harness connector. Repair any damaged wires, connectors, and open/spread terminals. If harness is OK, proceed with test. |
| 1. | Turn the ignition off. |
| 2. | Replace the Right Steering Wheel Switch in accordance with the Service Information (Refer to 08 - Electrical/8P - Speed Control/SWITCH, Speed Control - Removal) . |
| 3. | Turn the ignition on, engine not running. |
| 4. | Press and release each Speed Control Switch several times. |
| 5. | With the scan tool, read DTCs. |
Does the scan tool display this DTC as active?
Yes
- Replace the Powertrain Control Module (PCM) in accordance with the Service Information (Refer to 08 - Electrical/8E - Electronic Control Modules/MODULE, Powertrain Control/Removal) .
- Perform the POWERTRAIN VERIFICATION TEST (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
No
- Test Complete.
- Perform the POWERTRAIN VERIFICATION TEST (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).
