Outline
•
The OBD (on-board diagnostic) test inspects the integrity and function of the headlight auto leveling system
and output the results when reqested by the specitic tests.
•
OBD test also:
— Provides a quick inspection of the headlight auto leveling system.
— Is usually performed at the start of each deagnostic procedure.
— Provides verification after repairs to ensure that no other faults occurred during service.
•
Diagnostic DTC can be read/cleared, using the
SST
(WDS or equivalent).
•
The OBD test is divided into 3 tests:
— Read/clear diagnostic results, PID monitor and record and active command modes.
Read/clear diagnostic results
•
This function allows you to read or clear DTCs in the auto leveling control unit (main) memory.
Reading DTCs Procedure Using WDS or equivalent
1. Connect WDS or equivalent to the vehicle DLC-2
16-pin connector.
2. Turn the ignition switch to ON (Engine OFF) or
start engine.
3. Retrieve DTC by WDS or equivalent.
Clearing DTCs Procedures Using WDS or equivalent
1. After repairs have been made, perform the
reading DTCs procedure.
2. Turn the ignition switch to ON (Engine OFF) or start engine.
3. Erase DTC by WDS or equivalent.
4. Ensure that the customer
′
s concern has been resolved.
PID/Data Monitor and Record Procedure
1. Connect WDS or equivalent to the vehicle DLC-2
16-pin connector.
2. Turn the ignition switch to ON (Engine OFF) or
start engine.
3. Access and monitor PIDs by WDS or equivalent.
Note
•
The data monitor function monitors the
calculated values of input/output signals in
the auto leveling control unit (main) and the
auto leveling control unit (sub), and it does
not directly display monitored value faults as
faults in input/output parts themselves. If a
monitored value is not within the
specification it will be necessary to inspect input/output parts separately by such means as DTC
inspection or the active command modes function.
