With LEXUS Hand-Held Tester
DESCRIPTION
ECM controls the function of immobilizer on this vehicle. Data of the immobilizer or DTC can be read form DLC3 of the vehicle. When a trouble occurs on immobilizer, MIL does not light up but DTC inspection is performed. Therefore when there seems to be a trouble on immobilizer, use LEXUS hand-held tester or SST to check and troubleshoot it.
Check the DTC (Using LEXUS hand-held tester)
1. Prepare the OBD II scan tool (complying with SAE J1978) or LEXUS hand-held tester.
2. Connect the OBD II scan tool or LEXUS hand-held tester to DLC3 under the instrument panel lower pad.
3. Turn the ignition switch ON and turn the OBD II scan tool or LEXUS hand-held tester switch ON.
4. Use the OBD II scan tool or LEXUS hand-held tester to check the DTCs and freeze frame data; note them down. (For operating instructions, see the OBD II scan tool's instruction book.)
