Accessing OBD 1 Codes
Ensure ignition switched OFF.
Bridge data link connector (DLC) terminals GND and TEN Fig. 1 .
Connect LED test lamp between terminals FEN and B+ Fig. 1 .
NOTE: Connect LED test lamp positive connection to DLC terminal B+.
Switch ignition ON.
Count LED flashes. Note trouble codes. Compare with trouble code table.
Two digit trouble codes are displayed as follows:
Long flashes indicate the ‘tens’ Fig. 2 [A].
Short flashes indicate the ‘units’ Fig. 2 [C].
For example: Trouble code 12 displayed Fig. 2 .
Four digit trouble codes are displayed as follows:
Each trouble code consists of four groups.
A long flash indicates the start of each group Fig. 3 [A].
Short flashes indicate the digits of each group Fig. 3 [B].
No short flashes in a group indicate ‘0’.
For example: Trouble code 0120 displayed Fig. 3 .
Switch ignition OFF. Rectify faults as necessary.
Accessing Mazda OBD codes with OBD tools
Erasing Codes
Ensure ignition switched OFF.
Disconnect battery earth lead for at least 30 seconds.
Depress brake pedal for at least 20 seconds.
Reconnect battery earth lead.
Repeat checking procedure to ensure no data remains in ECM fault memory.
WARNING: Disconnecting the battery may erase memory from electronic units (e.g. radio, clock).
