- Always turn the key OFF and isolate both ends of a circuit
whenever testing for shorts or continuity.
- Never measure voltage or resistance directly at the processor connector.
- Always disconnect solenoids and switches from the harness before measuring
for continuity, resistance or energizing by way of a 12-volt source.
- When disconnecting connectors, inspect for damaged or pushed-out pins, corrosion,
loose wires, etc. Service if required.
