4.5 View Freeze Frame
Records and displays the vehicle conditions (e.g., engine speed, fuel system status, coolant temperature) at the exact moment an emission-related fault occurs.

4.6 O2 Sensor Test
Monitors and tests the operation of the oxygen (O2) sensors to identify problems that can affect fuel efficiency and vehicle emissions.
4.7 On-Board Monitor Test
Retrieves test results for emission-related powertrain components and systems that are not continuously monitored by the vehicle's computer.
4.8 EVAP System Test
Initiates a leak test for the vehicle’s Evaporative Emission Control System (EVAP system).
4.9 Battery Test
The OM129 offers an easy way to analyze the battery cell health status, view battery charging status, and detect faults and bad cells. It displays real-time voltage and voltage changes in a graph.
