| General Procedures Disconnect WARNING:Batteries normally produce explosive gases which may cause personal injury, therefore do not allow flames, sparks or lighted substances to come near the battery. When charging or working near the battery always shield your face and protect your eyes. Always provide adequate ventilation. Failure to follow these instructions may result in personal injury. WARNING:Batteries contain sulphuric acid, avoid contact with skin eyes or clothing. Shield your eyes when working near the battery to protect against possible splashing of the acid solution. In case of acid contact with the skin or eyes, flush immediately for a minimum of 15 minutes and seek prompt medical attention. If swallowed, call a physician immediately. Failure to follow these instructions may result in personal injury. WARNING:Audio unit key code saving devices must not be used when working on supplemental restraint or fuel systems. When using these devices the vehicle electrical system is still live but with a reduced current flow. Failure to follow this instruction may result in personal injury. CAUTION:Make sure the engine is not running before disconnecting the battery ground cable to avoid damage to the vehicle electrical system. NOTE:Before disconnecting the battery make sure that no data is required from the powertrain control module (PCM), as battery cable disconnection will erase any fault codes and idle/drive values held in the keep alive memory (KAM). It is not necessary to disconnect or remove electronic control modules. NOTE:This procedure should be used to disconnect the battery while carrying out repairs that refer to the battery being disconnected. | | -

CAUTION:Make sure all electrical systems are switched OFF before connecting the battery ground cable to avoid damage to the vehicle electrical system. | | -
Connect the battery ground cable. | | | -
NOTE:This step is only required for vehicles with 1.8L direct fuel injection. NOTE:Do not press the accelerator pedal or attempt to start the engine during the 30 second initialization period as this will cause the initialization process to fail. Turn the ignition key to position II for 30 seconds to initialize the throttle body. | | | -
Enter the audio unit keycode and preset radio frequencies. | | | -
Reset the clock to the correct time. | | | -
NOTE:When the battery has been disconnected and connected, the stored idle and drive values contained within the powertrain control module (PCM) will have been erased. The following steps must be carried out to allow the PCM to relearn its idle and drive values. Start and run the engine at idle for three minutes. | | | -
When the engine reaches normal operating temperature, increase the engine speed to 1200 rpm and maintain for approximately two minutes. | | | -
Drive the vehicle for approximately five miles/eight kilometers of varied driving. | |
