Renault PA0 Quickshift / Tecshift Diagnostic Fault Codes
The table below contains Renault PA0 robotised gearbox diagnostic fault codes and short recommended checks.
It applies to Renault Trafic II Phase 2 and Renault Master II Phase 3 systems with Vdiag 05 or 09.
Important: This is a diagnostic reference. A fault code does not automatically mean that the complete gearbox actuator must be replaced.
| Fault Code | Description | What to Check / Do |
|---|---|---|
| DF002 | Transmission control unit fault | Check gearbox ECU fuses, the 52-pin connector, permanent and ignition power supplies, grounds and wiring. If the fault remains, test or replace the control unit. |
| DF005 | Hydraulic pressure sensor circuit | Check the 30 A pump fuse, hydraulic-fluid level, pressure-sensor connector and wiring. Test pump operation. Replace the pressure sensor or pump unit if required. |
| DF039 | Engine speed information fault | Diagnose the engine-injection system. Check the gearbox ECU, injection ECU connectors and engine-speed signal wiring. |
| DF046 | Multiplexed idle-speed request fault | Test the CAN/multiplex network and diagnose the engine-injection system. |
| DF048 | Vehicle speed information fault | Check gearbox input speed, engine-speed information, clutch condition, speedometer operation, ABS connection and wiring. Perform a road test. |
| DF057 | Gearbox input-speed sensor circuit | Check sensor installation, connector and wiring. Verify vehicle-speed and engine-speed signals. Check clutch condition. Replace the sensor if necessary. |
| DF062 | CAN communication fault | Perform a complete CAN/multiplex network test. Check wiring, connectors, ECU power supplies and communication between control units. |
| DF065 | Hydraulic pump relay circuit | Diagnose DF005 first if present. Check the pump relay, relay socket, power supply, wiring, hydraulic pressure and pump motor. |
| DF066 | Starter relay circuit | Check the starter relay, relay socket, power supply, gearbox ECU connector and wiring. Test the relay with Renault CLIP command AC013. |
| DF067 | Gear lever position switch circuit | Check the gear-lever switch, connector and wiring. Verify lever-switch states ET043, ET044, ET045 and ET046 with Renault CLIP. |
| DF068 | Clutch position sensor circuit | Check sensor mounting, connector, wiring and the potentiometer mechanism. Inspect the clutch hydraulic circuit for leaks. Replace the sensor if necessary. |
| DF069 | Selection position sensor circuit | Check the sensor connector and wiring. Inspect the mechanical connection between the selection cylinder and potentiometer for wear, looseness or seizure. |
| DF070 | Engagement position sensor circuit | Check the sensor connector and wiring. Inspect the engagement cylinder-to-potentiometer linkage for excessive play, damage or seizure. |
| DF071 | Clutch solenoid valve circuit | Check the clutch-solenoid connector, ground and control wiring. Replace the clutch solenoid valve if the electrical circuit is correct. |
| DF072 | Engagement solenoid valve 1 circuit | Check the solenoid connector, ground and control wiring. Replace engagement solenoid valve 1 if necessary. |
| DF073 | Engagement solenoid valve 2 circuit | Check the solenoid connector, ground and control wiring. Replace engagement solenoid valve 2 if necessary. |
| DF074 | Selection solenoid valve 1 circuit | Check the solenoid connector, ground and control wiring. Replace selection solenoid valve 1 if necessary. |
| DF075 | Selection solenoid valve 2 circuit | Check the solenoid connector, ground and control wiring. Replace selection solenoid valve 2 if necessary. |
| DF076 | Clutch control fault | Check for clutch overheating, glazing and slipping. Inspect fluid level, hydraulic leaks, clutch actuator operation and the clutch solenoid valve. |
| DF077 | Gearbox control fault | Repair clutch and position-sensor faults first. Check the selection linkage, hydraulic pressure, solenoids, pressure accumulator, clutch cylinder and actuator. Perform gearbox learning after repair. |
| DF078 | Hydraulic control fault | Check that the pump starts at approximately 40 bar and stops at approximately 50 bar. Check fluid level, hydraulic leaks, pump condition and pressure accumulator. |
| DF080 | Battery voltage fault | Check the gearbox fuse, battery voltage, alternator output, battery terminals, engine grounds and ECU connectors. |
| DF082 | Brake switch and stop-lamp circuit | Check the stop-lamp fuse, brake-switch connector, switch installation and adjustment. Test the switch with the pedal pressed and released. |
| DF107 | Multiplexed engine-speed information fault | Repair DF062 first if present. Diagnose the injection system and engine-speed signal. |
| DF108 | Multiplexed actual engine-torque information fault | Repair DF062 first if present. Diagnose the injection system and engine-torque data. |
| DF144 | Multiplexed coolant-temperature information fault | Repair DF062 first if present. Diagnose the injection system and coolant-temperature sensor circuit. |
| DF145 | Multiplexed accelerator-pedal position fault | Repair DF062 first if present. Diagnose the injection system and both accelerator-pedal sensor tracks. |
| DF146 | Multiplexed engine-torque information fault | Repair DF062 first if present. Diagnose the injection system and engine-torque data. |
| DF148 | Multiplexed secondary brake-switch information fault | Repair DF062 first if present. Check the stop-lamp fuse, brake switch, adjustment, connector and wiring. |
| DF152 | Multiplexed total mileage information fault | Perform a complete CAN/multiplex network test. |
| DF153 | Reverse-lamp command circuit | Check the reverse-lamp relay, relay socket, power supply, gearbox ECU connector and wiring. Test with Renault CLIP command AC094. |
| DF183 | UCH body-control-module message absent | Perform a CAN/multiplex network test and check communication with the UCH body control module. |
| DF184 | Instrument-cluster message absent | Perform a CAN/multiplex network test and check communication with the instrument cluster. |
| DF186 | Injection ECU message absent | Repair DF062 first if present. Test the CAN network and communication with the injection ECU. |
| DF188 | Robotised gearbox system operation fault | Diagnose and repair all other present faults first. Clear the fault and road-test the vehicle. |
| DF189 | Gear-position learning fault | Run Renault CLIP command VP008. Confirm ET061 shows learning completed, then engage and verify every gear. Check actuators or internal gearbox mechanics if learning fails. |
| DF190 | Clutch-position learning fault | Run Renault CLIP command VP017. Cycle the ignition and confirm ET064 shows learning completed. |
