Technician Safety Information

IGNITION SYSTEM
- Ignition systems present a shock hazard, exercise care when performing spark test and always use non-conductive ignition wire pliers.
- Never pierce ignition leads or insulator boots to connect timing lights or analyzers. Use proper adapters.
- When removing a spark plug wire, twist boot one quarter turn and pull on boot only, never the lead itself.
- To disable ignition system, unplug primary connections only. NEVER disconnect secondary leads to disable ignition system.
- In case of poor performance (such as misfiring), avoid driving and correct problems as soon as possible.
- Do not disconnect spark plug wires with engine running.

BATTERY

NOTE: Before removing battery ground, access trouble codes. Powertrain Control Module (PCM) memory is erased when ground cable is removed.

- Batteries produce explosive hydrogen gas. Avoid creating sparks near battery.
- Ensure battery is properly connected prior to attempting to start engine.
- Do not disconnect battery when engine is running.
- Disconnect battery cables when charging battery.
- Disconnect the battery ground when replacing electronic components.
