ON-BOARD DIAGNOSTIC [DISCHARGE HEADLIGHT]
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 SST (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 SST (WDS or
equivalent).
Note
• The data monitor function monitors the
calculated values of input/output signals in
the discharge headlight control unit (LH) and
the discharge headlight control unit (RH),
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.
