With Service Wire

DTC Clearance (Using Service Wire)






a. Connect the 2 service wires to terminal Tc and AB of DLC1.
b. Turn the ignition switch to ACC or ON and wait for approx. 6 seconds.
c. Starting with the Tc terminal, ground alternately terminal Tc and terminal AB twice each in cycles of 1.0 seconds. Make sure that the terminals are grounded. Ensure the terminal Tc remains grounded.

HINT: When alternately grounding terminals Tc and AB, release ground from one terminal and immediately ground the other terminal within an interval of 0.2 seconds.

If DTCs are not cleared, repeat the above procedure until the codes are cleared.

d. Several seconds after doing the clearing procedure, the SRS warning light will blink in a 50-msec cycle to indicate the codes which have been cleared.
