Protege & Protege5

WARNING: This page is about a different car, the 2003 Mazda Protege5, 2003 Mazda Protege, 2003 Mazda MX-5 Miata, 2003 Mazda MPV, and 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect clutch switch harness connector. Remove clutch switch. Using ohmmeter, check continuity between clutch switch terminals. With clutch rod released, continuity should be present. With clutch rod depressed, continuity should not be present. If continuity is as specified, check for open or short circuit. Go to next step. If continuity is not as specified, replace clutch switch.

Open Circuit Inspection

Disconnect PCM 104-pin harness connector and install 104-Pin Breakout Box (49-UN01-130) to PCM harness connector only. See Figure. Check for continuity in following circuits:
- Check for open in signal circuit between clutch switch harness connector terminal "B" (White/Green wire) and breakout box terminal No. 6 through common connector.
- Check for open in ground circuit between ground and clutch switch harness connector terminal "A" (Black wire).
If continuity is present, go to next step. If continuity is not present, repair open circuit in suspect wire or replace wire harness. See appropriate WIRING DIAGRAM under ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS.

Short Circuit Inspection

Check for continuity to ground in signal circuit between clutch switch harness connector terminal "B" (White/Green wire) and breakout box terminal No. 6 through common connector.
If continuity is present, repair short circuit to ground in White/Green wire between clutch switch harness connector terminal "B" and PCM 104-pin harness connector terminal No. 6 through common connector or replace wire harness.
