Data list / active test
1. DATA LIST
(a) While the intelligent tester is connected to the DLC3
with the ignition switch in the ON position, the ABS
data list can be displayed. Follow the prompts on
the tester screen to access the DATA LIST.
2. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the intelligent te ...
Air-fuel ratio (a/f) and heated oxygen (ho2)
sensor heater monitors (front a/f and rear ho2 sensor
type)
(a) Preconditions
The monitor will not run unless:
The MIL is OFF.
(b) Drive Pattern
(1) Connect an intelligent tester to the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Clear the DTCs.
(4) Start the engine.
(5) Allow the engine to idle for 10 minutes or more.
