C001D Code: Right Rear Outlet Control
C001D: Right Rear Outlet Control
Save the complete ABS/ESC event and distinguish the right-rear ABS outlet valve before testing the hydraulic-control circuit.
DIAGNOSTIC FOCUS
The generic Scanator code list supports reader-facing terminology. The Mitsubishi document provides a bounded Outlander PHEV implementation mapping, not a universal valve procedure.
C0019: RR LH ABS OUT valve. Save the complete ABS/ESC scan, confirm the reporting module and VIN-specific valve mapping, then prove the power, connector, circuit, actuator or hydraulic branch required by the OEM procedure.
A C-code label does not prove a failed valve, HCU or control unit. Brake-system warnings require safe triage and qualified service when braking or stability behavior changes.
What Does the C001D Code Mean?
The generic Scanator list labels C001D as Right Rear Outlet Control. In the 2023 Mitsubishi Outlander PHEV brake-control index, GST C001D is associated with OEM DTC C1050-04 and the right-rear ABS outlet valve display. That is an application example, not a universal definition.
The inlet/outlet distinction describes two hydraulic-control branches at the right-rear circuit. It is not a wheel-speed-sensor label and does not identify an electric parking-brake actuator. A different platform may expose another suffix, display code or valve numbering.
Confirm the reporting module, full suffix, VIN, hydraulic-unit layout and current OEM test before choosing electrical, actuator or hydraulic checks. Do not import a Mitsubishi pinout, threshold or HCU replacement rule.
Preserve active/stored status, suffix, freeze-frame or event data and all companion ABS/ESC/voltage/network codes.
Match the scanner wording to the VIN-specific hydraulic unit and module documentation before testing.
Separate supply/ground, connector/terminal, harness, actuator and hydraulic branches with the prescribed tools.
C001D Symptoms, Severity, and Driving Safety
Record the lamp, status and operating conditions; a warning does not identify the failed component.
The controller may suspend TCS when the monitored brake-control path is unavailable.
Treat any changed braking feel as a safety issue; do not continue testing on public roads.
Timing is a clue only; inspect the disturbed connector and harness under the OEM procedure.
Stored versus active status changes the next step; preserve the complete event before clearing.
Shared power, network or sensor conditions may change the diagnostic order.
Brake and stability warnings are safety-relevant. Stop safely if pedal feel, steering, braking or stability control changes. No fixed safe driving distance can be established from this code.
C001D Causes and the Evidence That Separates Them
These are diagnostic branches, not a parts list. Choose among them from the complete event and failed test.
Power, ground, fuse or relay issue
The controller can lose a stable supply or ground while monitoring the named valve branch; this can be reported as a valve-control issue without proving the actuator itself is failed.
How to prove it: Check the VIN wiring diagram, feeds, grounds and voltage drop under the OEM procedure.
Check firstConnector or terminal fit problem
Inlet and outlet valves are distinct hydraulic-unit branches. A connector or terminal issue can interrupt one branch while wheel-speed sensing remains normal.
How to prove it: Inspect retention and corrosion, then perform the specified harness and terminal checks.
Check firstOpen or shorted valve branch
A harness fault can make the expected valve response unavailable without proving a failed HCU.
How to prove it: Compare the circuit to the vehicle-specific schematic and use only its specified measurements.
Verify directlyValve coil or actuator fault
The monitored valve may not respond electrically or mechanically in the documented application.
How to prove it: Use the supported actuator test and the OEM electrical/hydraulic procedure to separate coil, valve and unit branches.
Verify directlyHydraulic or mechanical restriction
A valve-control code can coexist with a hydraulic concern, but the DTC alone cannot prove pressure loss or contamination.
How to prove it: Follow the brake manufacturer’s pressure/bleeding procedure only with qualified equipment.
Verify directlyStored or application-mismatched record
A stored event or generic translation may not represent an active failure in this vehicle.
How to prove it: Compare active/stored status, full suffix, companion codes and VIN-specific service information before parts.
Final branchA valve label does not prove an HCU or module failure. Verify the architecture and active/stored state first.
Using JU2000 MAX During C001D Diagnosis
On a supported VIN, iCARZONE JU2000 MAX can preserve accessible ABS/ESC codes, available event data and supported live data before clearing C001D. Coverage and active tests vary by vehicle software.
Use the scan tool to identify the reporting module, OEM display code, status and companion codes. Circuit continuity, terminal fit, actuator behavior, hydraulic pressure and bleeding still require the correct external tools and service procedure.
Confirm VIN-specific ABS/ESC coverage and any required active test before purchase. The JU2000 MAX product page lists broader functions and TPMS equipment, but that is not proof of C001D support on every vehicle.
iCARZONE JU2000 MAX All-in-One Diagnostic & TPMS Kit
Preserve the complete brake-control event. Confirm exact VIN coverage and supported ABS/ESC functions before purchase.
Brake-system repair, hydraulic opening, actuator commands and calibration should follow qualified service procedures.
How to Diagnose C001D in 6 Steps
Use these six decisions with the current OEM procedure. Preserve the original event and stop when unsafe conditions prevent a valid test.
C001D Quick Diagnostic Path
-
1
Preserve the event
- Save status, suffix and companion codes
- Record the complete ABS/ESC event before clearing.
-
2
Identify the architecture
- Match valve name to VIN module
- Match C001D to the vehicle's actual ABS/ESC hydraulic-unit diagram and OEM display code. The generic label does not prove the physical valve location.
-
3
Check prerequisites
- Verify battery, fuses, feeds and grounds
- Use the prescribed supply and ground checks; do not import another vehicle’s values.
-
4
Inspect the branch
- Check connector, terminal and harness
- Inspect right-rear inlet/outlet connector and terminal retention, then separate the hydraulic-control branch from wheel-speed sensing and the parking-brake actuator.
-
5
Prove the fault
- Use supported scan and physical tests
- Use supported scan and VIN-specific electrical or hydraulic tests. A stored record may be treated differently from an active fault; clearing is not a repair.
-
6
Verify the repair
- Rerun the monitor safely
- Clear only after repair and repeat the required scan and brake-control verification.
How to Fix C001D and Verify the Repair
Repair a proven power or ground fault
Correct the demonstrated feed, fuse, relay or ground issue and repeat the OEM check.
Repair a proven connector or harness fault
Restore terminal fit or wiring only after the failed branch is documented.
Service a proven valve or actuator branch
Use the exact component and hydraulic procedure; a code alone is not authorization.
Replace or reprogram a unit only when proven
Follow VIN-specific module and calibration instructions after external branches pass.
Diagnostic allowance
VIN-specific quoteRequest an itemized ABS/ESC diagnostic allowance tied to the failed branch.
Parts and labor
VIN-specific quoteIdentify the VIN-specific component and separate parts, labor, fluid and taxes.
Hydraulic or programming setup
VIN-specific quoteInclude bleeding, calibration or programming only when the OEM repair requires it.
Verification
VIN-specific quoteRetain pre- and post-repair scans and the specified brake-system verification.
Request a VIN-specific estimate after the cause is proven; do not authorize an HCU or module from the C-code label alone.
Retain the original and final scan records and the test result that supports the repair.
C001D OEM Differences and DIY Limits
Use the cited Mitsubishi mapping only as a documented OEM example. Confirm the exact vehicle, controller, suffix and hydraulic layout before applying it.
Mitsubishi Motors North America TSB-23-35-002 covers the documented 2023 Outlander PHEV brake-control architecture. Its DTC index provides an application mapping only; it is not a universal C-code definition, pinout, threshold or repair instruction. The index maps C0019 to RR LH ABS OUT valve.
The source identifies C0019 as RR LH ABS OUT valve in that Mitsubishi application. It does not establish a universal meaning, threshold or replacement rule.
Valve numbering and control architecture vary. Do not transfer the Mitsubishi label or procedure to another vehicle without matching VIN documentation.
Brake system safety, hydraulic service and calibration instructions vary by OEM; current service information controls.
- Save the scan without clearing the event.
- Record warnings, pedal feel and recent service.
- Inspect only safe external areas with the vehicle secured.
- Ask the repairer which test result supports the proposed repair.
- Leave hydraulic opening, actuator commands and calibration to qualified service.
- Use the OEM brake safety procedure.
- Do not probe or bypass safety circuits.
- Stop if braking or stability behavior is abnormal.
