Bosch OBD1300 Scan Tool

This code indicates that the vehicle's self-test completed successfully without finding any active problems during the Key On, Engine Running (KOER) test. It means the Powertrain Control Module (PCM) has passed the diagnostic check.

Code 12 means the engine control module (ECM) is not receiving a signal indicating the engine's rotational speed. This is often expected when the engine is not running, but if displayed during a test with the engine off, it indicates a problem.

This confirmation message appears after the 'Erase Codes' function has been completed. It indicates that all diagnostic trouble codes (DTCs) have been successfully cleared from the vehicle's memory.

This message appears after you initiate a function like 'Erase Codes'. It indicates the scan tool has successfully sent the command to the vehicle's control module.

This message indicates that the Cylinder Balance Test has detected a problem with one or more engine cylinders. The tool will display a list of the failed cylinders.

This error message appears during the Cylinder Balance Test if the throttle pedal is moved after the initial press and release, or if noise from the throttle position sensor interferes with the test.

This code, often displayed with 'Sys Pass' or 'No Faults Detected', indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has successfully completed the Key On, Engine Off (KOEO) diagnostic test without identifying any issues.

An error message indicates a problem that needs attention. This can happen if the connection is not secure or if the vehicle's computer needs to be reset.

The scan tool beeps and displays a 'FAULT PRESENT' message when it detects an intermittent electrical fault during a Wiggle Test. This indicates a problem with a sensor or wiring connection.

The scan tool has reached its limit for stored vehicle profiles. You need to delete an existing profile to add a new one.

This message confirms that the diagnostic trouble codes stored in the vehicle's continuous memory have been successfully erased. This is typically done after servicing a known fault.

This message appears when the scan tool has completed its search for diagnostic trouble codes (DTCs) and found none in the vehicle's computer.

This message appears when you attempt to erase codes. It informs you that only 'memory codes' (Continuous Memory Codes) can be cleared without repairing the fault. KOEO and KOER codes require the fault to be fixed first.

This message indicates that the scan tool is currently processing the 'Erase Codes' command and communicating with the vehicle's control module. It requires a short period to complete.

This message appears when attempting to run the KOEO (Key On, Engine Off) self-test function multiple times without cycling the ignition. The Ford system restricts self-tests to one per ignition cycle.

A beep sound accompanies each time the STO (Self-Test Output) signal goes low during the STAR Test Mode. This indicates the scan tool is receiving a signal related to the vehicle's self-test.

This message displays on the scan tool screen while the Key On, Engine Off (KOEO) Slow Codes test is actively retrieving diagnostic trouble codes (DTCs) from the vehicle's Powertrain Control Module (PCM).

This indicates that the Throttle Position Sensor (TPS) or the pedal position is reporting a value that is outside the expected range. This can affect engine performance and diagnostics.

This message indicates that the throttle position sensor (TPS) or the accelerator pedal position is reporting a value outside the expected range during a self-test. This can affect engine performance and idle control.

The scan tool is not getting power from the vehicle's OBD-II port. This means it cannot communicate with the car's computer systems.
