Pad, Heater: Removal
Disable the airbag system before attempting any front seat diagnosis or service. Disconnect and isolate the negative battery (ground) cable and wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.
On all models, the front passenger seat bottom contains an Occupant Detection Sensor (ODS) to provide information to the Occupant Restraint Controller (ORC).
