A professional workshop may charge a diagnostic fee each time a Peugeot warning light appears.

With a compatible Peugeot diagnostic scanner, users can perform initial fault-code checks, review live sensor data and identify the affected system before replacing parts.

This can help reduce unnecessary repairs and improve workshop efficiency.

OE-Level Full-System Diagnosis for Peugeot Vehicles

Scan Multiple Electronic Control Modules

The LAUNCH X431 Elite Peugeot scanner can communicate with supported electronic control units throughout the vehicle.

A full-system scan can help identify faults that may not appear through a basic engine-only code reader.

Typical systems may include:

• ECM or PCM

• TCM

• ABS

• SRS

• EPB

• BMS

• TPMS

• SAS

• BCM

• HVAC

• Instrument cluster

• Gateway

• Parking-assistance system

Read and Clear Diagnostic Trouble Codes

The scanner can read stored, pending and manufacturer-specific trouble codes from supported modules.

After the vehicle has been correctly inspected and repaired, the tool can clear eligible diagnostic trouble codes.

Clearing a fault code without repairing the underlying problem does not fix the vehicle. If the fault remains, the warning light may return.

Read ECU Information

The device can display available electronic control unit information, such as:

• ECU identification

• Module name

• Hardware number

• Software number

• Calibration information

• Control-unit version

• Vehicle configuration information

This information can be useful when diagnosing communication problems or replacing electronic modules.

View Freeze-Frame Data

Freeze-frame data records operating conditions when certain faults are detected.

Depending on the vehicle and control module, available information may include:

• Engine speed

• Vehicle speed

• Coolant temperature

• Intake-air temperature

• Throttle position

• Fuel-trim data

• Battery voltage

• Engine load

Freeze-frame data can help technicians understand when and how a fault occurred.

Peugeot Bidirectional Control and Active Tests

What Is Bidirectional Control?

Bidirectional control allows the diagnostic scanner to send commands to a supported vehicle control module.

Instead of waiting for a component to operate during normal driving, the technician can command the component to activate through the scanner.

This helps determine whether the fault comes from:

• The electronic control unit

• A wiring problem

• A sensor

• A relay

• An actuator

• The mechanical component itself

Supported Active Tests May Include

Depending on the Peugeot model and year, available active tests may include:

• Turn the cooling fan on or off

• Activate the fuel pump

• Operate the horn

• Switch exterior lights on or off

• Operate interior lighting

• Control the windshield wipers

• Test door locks

• Raise or lower supported windows

• Activate the air-conditioning compressor

• Test injectors

• Operate valves or solenoids

• Test electronic parking brake components

• Perform ABS pump activation

• Test instrument-cluster indicators

• Calibrate supported seats

• Operate the sunroof

• Test parking-assistance components

Why Active Testing Is Useful

Suppose a Peugeot cooling fan does not operate when the engine becomes hot.

With bidirectional control, the technician may command the fan to run.

If the fan responds, the motor and power circuit may be functional, and the fault may be related to a sensor, control command or operating condition.

If the fan does not respond, further inspection may be required for the fan motor, relay, fuse, wiring or control module.

This method can reduce diagnostic time and unnecessary component replacement.
