The rear right actuator output solenoid valve is one of the coeds stored on the ABS along with the rear right sensor broken circuit. any solution about the valve?

Look at the transmission control module. Sounds like a massive wiring harness problem too.

Before you replace a part you may or may not need . Why ? What code ? Does the vehicle run ? There has been a lot of confusion on these vehicles with variable valve timing , mixing up cam sensors with camshaft actuators
DTC P0008: Engine Position System Performance Bank 1

DTC P0009: Engine Position System Performance Bank 2
The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no longer referenced to top dead center (TDC).

?€¢
Observe the scan tool CMP Desired, Actual, and Angle Variance parameters before a DTC sets. This may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

Camshaft Position (CMP) Actuator System
The camshaft position (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by changing the angle or timing of the camshaft relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.
During engine OFF, engine idling conditions, and engine shutdown, the camshaft actuator is held in the Park position. Internal to the CMP actuator assembly is a return spring and a locking pin. During non-phasing modes of the camshaft, the return spring rotates the camshaft back to the Park position, and the locking pin retains the CMP actuator sprocket to the camshaft

You need to find out what code is stored in the ABS control module, if the light is on there is a DTC an the system is disabled ! Don't know if auto part stores can pull ABS codes or not , You'll have to check it out . Personally I say take it to a ASE certified repair shop if you don't know anything about anti lock brakes !
?€¢
Electronic Brake Control Module (EBCM) -- The EBCM controls the system functions and detects failures.

The EBCM contains the following components:

?€¢
System Relays -- The inlet and outlet solenoid relay is energized when the ignition is ON and no ABS DTCs are present. It supplies battery positive voltage to the solenoid valves, the pump motor relay is energized and supplies battery positive voltage to the pump motor when ABS is activated.

?€¢
Brake Pressure Modulator Valve (BPMV) -- The BPMV contains the hydraulic valves and pump motor that are controlled electrically by the EBCM. The BPMV uses a 4 circuit configuration with a diagonal split. The BPMV directs fluid from the reservoir of the master cylinder to the left front and right rear wheels and fluid from the other reservoir to the right front and left rear wheels. The diagonal circuits are hydraulically isolated so that a leak or malfunction in one circuit will allow continued braking ability on the other.

This system can store 10-12 DTC's for something simple as wheel speed sensors to wiring problems to a malfunction of the EBCM . Some of these problems you would need a professional type scan tool ! The antilock brake system on your vehicle is the

Important: There is a rubber isolator located under the BPMV and on the mounting studs. The rubber isolators protect the BPMV and the EBCM from vehicle vibrations.

?€¢
The BPMV contains the following components:

-
Pump Motor

-
Inlet Valves (one per wheel)

-
Outlet Valves (one per wheel)

?€¢
Wheel Speed Sensors (WSS) -- As the wheel spins, the wheel speed sensor produces an AC signal. The EBCM uses this alternating current signal to calculate wheel speed. The wheel speed sensors are replaceable only as part of the wheel hub and bearing assemblies.

?€¢
Traction Control Switch (w/NW7) -- The TCS is manually disabled or enabled using the traction control switch.

?€¢
Stop Lamp Switch - The EBCM uses the stop lamp switch as an indication that the brake pedal is applied

Error logs are a great thing. They will help you find intermittent problems and start you off in a general direction of where a problem could be. There is a great level of detail on the justcommodores site on checking error codes logged by the engine management system, but this does not detail anything about the abs system. The abs warning light is not as common as the check engine warning light. Reading through the posts, I haven't found any detail on checking error codes logged by the abs system.

So here it is. For those of you familiar with checking the engine error codes, this procedure is so simple its not funny.

Basically, to check the engine error log, you bridge the 5th (ground) and 6th pins in the ODB connector under the steering wheel.

To check the ABS error log, using the same trusty calibrated paper clip, you simply bridge pins 5 and 12 of the connector.

To find pins 5 and 12, start at the top left hand corner. That is pin one. Going to the right, you count pin 2,3,4 etc. Once you get to the end, jump back to the start of the bottom left level of pins and keep counting. Pin 5 is about halfway along the top row, pin 12 is a little left of the middle in the bottom row.

Reading the error codes is the same procedure (counting the flashes), except now, the ABS light flashes (as opposed to the engine light when checking the engine codes).

The ABS log also uses code 12 firstly, with any errors logged shown after that. If no errors are logged, the 12 will flash again.

Error codes for the ABS error log (VR/VS) are as follows:

12 Diagnostic system operational
21 Right hand front wheel speed sensor fault
23 Right hand front wheel speed sensor continuity fault
25 Left hand front wheel speed sensor fault
27 Left hand front wheel speed sensor continuity fault
28 Wheel speed sensor frequency error
31 Right hand rear wheel speed sensor fault
33 Right hand rear wheel speed sensor continuity fault
35 Left hand rear wheel speed sensor fault
37 Left hand rear wheel speed sensor continuity fault
41 Right hand front inlet solenoid valve circuit fault
42 Right hand front outlet solenoid valve circuit fault
45 Left hand front inlet solenoid valve circuit fault
46 Left hand front outlet solenoid valve circuit fault
55 Rear inlet solenoid valve circuit fault
56 Rear outlet solenoid valve circuit fault
61 Pump motor relay circuit fault
63 Valve relay circuit fault
71 ABS control module internal fault

The above guide has been verified on a VR/VS. Checking the error log on all models prior to VR/VS is the same for the engine log, and I would assume that the same can be said for the ABS log, would be happy if someone could verify this for me.

The code P0014 is for Camshaft Positon Sensor Actuator Bank 1. The possible causes are incorrect camshaft timing, wiring problems (harness/wiring) in intake timing control valve solenoid system; continuous oil flows to VCT piston chamber or failed timing valve control solenoid(stuck open).
The code P0015 is for Camshaft Position -Timing Over-******** (Bank 1). Your problem will probably be that the timing will be slightly out, due to wear (stretch) of the timing chain; this will all be linked to the overall cold start issue and the timing position. Get that timing checked, or push for the full fix for the cold start timing issue.

• ABS pump runs longer than 2 minutes.
• Vehicle is driven with parking brake on longer than 30 seconds.
• One rear wheel is locked.
• Wheel speed sensor does not transmit a signal.
• Vehicle is driven on extremely rough road.
• Low battery voltage.

RWAL Fault codes
Codes for Dodge RWAL, Ford RABS and GM RWAL applications are similar but have a few differences:

1. Should not occur (replace the controller if it does)
2. Open isolation valve circuit or defective ABS module
3. Open dump valve circuit or defective ABS module
4. Grounded or closed RABS or RWAL valve switch
5. Excessive actuations of dump valve during ABS braking
6. Erratic speed sensor signal
7. Shorted isolation valve or defective ABS module
8. Shorter dump valve or defective ABS module
9. High resistance or open speed sensor circuit (resistance should be 1000 to 2500 ohms)
10. Low speed sensor resistance (Dodge & Ford only)
11. Open speed sensor circuit (GM only)
12. Stop lamp switch circuit (Dodge & Ford)
13. ABS module speed processor (Dodge & Ford only)
14. ABS module program (Dodge & Ford only)
15. ABS module RAM memory failure (Dodge & Ford)

To manually clear a stored fault code on GM and some Dodge trucks with RWAL, remove the ABS fuse or disconnect the battery for 5 seconds. Ford RABS codes will automatically clear when the ignition is turned to the off position.
