WARNING:
Ultracapacitors should not be opened, disassembled, crushed, burned, charged over 5V, or exposed to high temperatures greater than 81.6°C (179°F). Ultracapacitors contain acetonitrile. If ultracapacitor leaks or ruptures it will emit flammable liquid and vapor with an aromatic ether-like odor. Harmful if inhaled or absorbed through the skin. Causes respiratory tract, eye, and skin irritation. May be harmful if swallowed. Can cause target organ damage. Arcing may also occur when charged and shorted, resulting in molten metal splattering and arc-flash hazards. To reduce the risk of personal injury and/or vehicle damage:
• Do not breath vapor or mist, assure adequate ventilation of area.
• Do not ingest.
• Do not eat, drink or smoke when using this product.
• Avoid contact with eyes, skin and clothing. In case of exposure to ultracapacitor contents, wash affected area for at least 15 minutes with generous amounts of water and seek medical attention.
• Keep away from heat sparks and flame.
• Remove jewelry before handling.
• Follow diagnostic and repair procedures to discharge the ultracapacitor and disconnect the negative battery terminal when requested.
1. Ignition OFF, disconnect the C1 Battery (disconnect negative cable of the battery).
2. Disconnect the X5 harness connector at the K176 Stop/Start Capacitor Control Module.
3. Test for less than 10 Ω between the ground circuit terminal A and ground.
   • If 10 Ω or greater 
   1. Ignition OFF.
   2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
   • Go to next step: If less than 10 Ω 
4. Reconnect the X5 harness connector at the K176 Stop/Start Capacitor Control Module.
5. Reconnect the C1 Battery.
