Inspection/Maintenance Monitor Test
(Mode $01)
The
Inspection/Maintenance Monitor Test ($01)
lets you view the Drive Cycle Procedures for all
monitors supported by the vehicle. A Drive Cycle
for a monitor requires that the vehicle is driven in
such a way that all the required “Enabling Criteria”
for the monitor to run and complete its diagnostic
testing are met. You can use the tablet to view the
Drive Cycle procedures for a selected Monitor.

Oxygen Sensor (Mode $05)
The
Oxygen Sensor (Mode $05)
lets you view the test results of the vehicle’s two or more O2 sensors. These
sensors are designed to help identify problems that can reduce fuel efficiency or increase emissions. Each O2
sensor has a unique name that identifies its location in the exhaust system – cylinder bank location (bank 1 or
bank 2) and its location in relation to the catalytic converter (
upstream
or
downstream
). Please reference the
vehicle’s service manual for further information.
NOTE:
Service Mode $05 is not supported in ISO 15765-4 (CAN) applications
– it includes the majority of 2008 and older vehicles. For CAN applications, the
functionality of Service Mode $05 was implemented in Service Mode $06.
