Symptoms
Hard cold starts, a long crank before it fires, or an engine that cranks but won't start at all. A loose wire at the glow-plug bus bar or a burned trace inside the controller can stop everything.
The fix, step by step
- The controller learns how hot the plugs are by measuring their resistance and runs 6 V plugs on a 12 V system through two relays.
- That's why generic 6 V plugs (often CP-06 types) don't work with it.
- Delica.ca members fit Mitsubishi MD092392 or NGK 2161.
- Check the bus-bar connection first.
- On right-hand-drive vans the controller sits in the driver's-side B-pillar behind the seat-belt reel.
- One owner found a burned trace to the relay and bridged it with wire.
- Don't keep cranking a no-start engine to warm it up: that overheats the glow relay and controller.
Tools & part numbers
- Multimeter
- deep socket for the glow plugs
- anti-seize
