5. Advanced Diagnostic Techniques with the Autel MP408

Once you’ve mastered the basics, you can move on to more advanced diagnostic techniques using the Autel MP408. These techniques will enable you to diagnose more complex issues and gain a deeper understanding of vehicle systems.

5.1. Diagnosing Sensor Issues

Sensors are critical components in modern vehicles, and diagnosing sensor issues requires a thorough understanding of their operation and signal characteristics.

Identify the Sensor: Determine the type of sensor you are testing (e.g., MAP sensor, TPS, O2 sensor).
Locate the Signal Wire: Refer to the vehicle’s wiring diagram to identify the sensor’s signal wire.
Connect the Test Leads:
- Connect the black test lead to a known good ground.
- Connect the red test lead to the sensor’s signal wire.
Analyze the Waveform:
- Check the sensor’s output voltage or frequency.
- Look for any anomalies in the waveform, such as flat lines, spikes, or dropouts.
- Compare the waveform to a known good waveform.
Example: Diagnosing a MAP Sensor

The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. A faulty MAP sensor can cause poor engine performance, reduced fuel economy, and diagnostic trouble codes (DTCs).
- Normal Operation: The MAP sensor’s output voltage should change as the engine’s vacuum changes.
- Fault Diagnosis: If the MAP sensor’s output voltage is flat or erratic, it may be faulty.

5.2. Diagnosing Actuator Problems

Actuators control various functions in a vehicle, such as fuel injection, ignition timing, and valve operation. Diagnosing actuator problems requires testing their response to control signals.

Identify the Actuator: Determine the type of actuator you are testing (e.g., fuel injector, ignition coil, solenoid).
Locate the Control Wire: Refer to the vehicle’s wiring diagram to identify the actuator’s control wire.
Connect the Test Leads:
- Connect the black test lead to a known good ground.
- Connect the red test lead to the actuator’s control wire.
Analyze the Waveform:
- Check the actuator’s pulse width and frequency.
- Look for any anomalies in the waveform, such as missing pulses or irregular patterns.
- Verify that the actuator is responding correctly to the control signals.
Example: Diagnosing a Fuel Injector

Fuel injectors control the amount of fuel delivered to the engine. A faulty fuel injector can cause misfires, poor performance, and DTCs.
- Normal Operation: The fuel injector’s pulse width should vary depending on the engine’s load and speed.
- Fault Diagnosis: If the fuel injector’s pulse width is too short or too long, or if there are missing pulses, the injector may be faulty.

5.3. Diagnosing Communication Issues (CAN, LIN, FlexRay)

Modern vehicles use various communication protocols, such as CAN, LIN, and FlexRay, to allow different electronic control units (ECUs) to communicate with each other. Diagnosing communication issues requires analyzing the data signals on these networks.

Identify the Network: Determine the type of network you are testing (e.g., CAN, LIN, FlexRay).
Locate the Network Wires: Refer to the vehicle’s wiring diagram to identify the network wires.
Connect the Test Leads:
- Connect the black test lead to a known good ground.
- Connect the red test lead to one of the network wires.
Analyze the Waveform:
- Check the signal voltage levels.
- Look for any anomalies in the waveform, such as missing signals or distorted patterns.
- Use the Autel MP408’s decoding functions to analyze the data being transmitted on the network.
Example: Diagnosing a CAN Bus Issue

The Controller Area Network (CAN) bus is a common communication protocol used in vehicles. A CAN bus issue can cause various problems, such as DTCs, warning lights, and system malfunctions.
- Normal Operation: The CAN bus signals should have a specific voltage level and waveform pattern.
- Fault Diagnosis: If the CAN bus signals are missing, distorted, or have incorrect voltage levels, there may be a problem with one of the ECUs or the wiring harness.
