WARNING: This page is about a different car, the 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
- Use 2 jumper wires. Connect one end of first jumper wire to DLC3 terminal Tc and one end of second jumper wire to DLC3 terminal AB. See Figure. Turn ignition switch to ON position. Wait about 6 seconds.NOTE: When alternately grounding terminals Tc and AB, release ground from one terminal and immediately ground the other terminal within 0.2 second. If time interval exceeds 0.2 second, DTCs will not be cleared.
- Starting with jumper wire connected to terminal Tc, apply body ground alternately to terminal Tc and terminal AB twice each, in cycles of 1/2 to 1 1/2 seconds (sequence is: Tc, AB, Tc, AB). Finally, keep applying body ground to terminal Tc until AIR BAG warning light flashes quickly, indicating DTCs are cleared.
