Starter Interlock Switch Inspection
WARNING: This page is about a different car, the 2004 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not reuse the starter interlock switch if it is removed from the vehicle even once. Please replace with a new starter interlock switch when installing.
- Disconnect the negative battery cable.
- Disconnect the starter interlock switch connector.
- Inspect for continuity between terminals of the starter interlock switch using an ohmmeter. See Fig 1. There should be continuity with the clutch pedal depressed between (A) and (B) terminals, and there should not be continuity when released. If not as specified, replace the starter interlock switch.
