Scan Tool Testing and Procedures

Switch Monitor Function:






NOTE: This test requires use of Mazda Special Service Tools (SST). To determine if aftermarket "Scan" tools will perform this function, check with manufacturer.

1. Warm engine to operating temperature and switch ignition "OFF."
2. Connect Self-Diagnosis Checker (SST #49 H018 9A1) to check connector (Green: 6-pin) and negative battery terminal.
3. Connect a jumper wire between test connector (Green: 1-pin) and ground.
4. Turn ignition switch "ON." Check if monitor lamp illuminates when each switch is made to function as described on Switch Check Chart.

CAUTION: When any switch is activated, monitor lamp will stay "ON." Do not start engine.

If malfunctions are detected, check individual switches with this chart and refer to COMPONENT TESTING if required:
