Unlike North American OBD-II equipped TAs (equipped with OBD interface ports), DTCs on E-OBD equipped vehicles must read the 4-digit EOBD DTCs via a grey or black DIAGNOSIS connector mounted to the firewall.
Step 1: With the ignition in the OFF position, use a jumper wire to connect the TEN and GRD terminals.
Step 2: Connect a test light to the B+ and FEN terminals.
Step 3: Turn the ignition to the ON (not START) position.
Step 4: If there are any stored DTCs, the test light will flash the four digit code followed by a four second pause, then a different four digit code if other DTCs are present. If only one code is stored, it will be repeated after a four second pause.
Step 5: Return the ignition to the OFF position before disconnecting the test light or jumper wire.
Step 6: To clear codes, disconnect the negative battery terminal for 45 seconds and reconnect.
