What This Product Does
The unit provides an electrical switching function within the engine ignition assembly. Although described as an ignition switch unit, its application should not be confused with a steering-column switch that controls accessory power and starter engagement.
Functions
- Provides switching within the ignition system.
- Replaces a faulty unit where the vehicle application and six-pin connection match.
Technical Details
- Product reference: 92860270601.
- Brand: OE Match.
- Connection specification: 6 pin.
Symptoms of Fault
Ignition-system faults may cause difficult starting, intermittent failure to start, uneven running or stalling when hot. These symptoms are not conclusive evidence of a defective switching unit: wiring, connectors, power supplies and other ignition components can produce similar behaviour.
Why Replacement Matters
Renewal is appropriate when testing identifies the unit as the cause of an ignition fault. Establishing the cause before fitting a replacement helps avoid unnecessary parts changes. Inspect the connector and surrounding wiring, and confirm the vehicle specification and original reference rather than relying on appearance alone.
FAQs
Is this a replacement key barrel?
No. This listing concerns the six-pin engine ignition switching unit, not the mechanical lock barrel.
What should be checked before replacement?
Check battery condition, earth connections, connector condition and the relevant electrical signals before condemning the unit.
How many units does a 964 require?
The supplied diagram records two for its listed 964 engine applications. Confirm the repair requirement separately from the quantity being ordered.
