Battery Reconnect Procedure
WARNING:
If the battery has been on bench charge, the cells may be giving off explosive hydrogen gas. Avoid creating sparks and if in doubt, cover the vent plugs or covers with a damp cloth.
CAUTION:
Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or damage to sensitive electrical equipment.
NOTE:
Whether one or both cables were disconnected, a minimum of 30 seconds MUST elapse between disconnection of the first cable and connection of the last cable. A clean final connection must be made. Do not allow temporary contact.
- Always reconnect the battery positive lead first and the negative battery cable last, ensuring that there is a good electrical contact and the battery terminals are secure. Tighten the battery cable clamp to specification. See TORQUE SPECIFICATIONS .
- Reset the clock.
- Enter the radio security code.
- Following reconnection of the battery, the engine should be allowed to idle until it has reached normal operating temperature as the stored idle and drive values contained within the ECM have been lost. Allow the vehicle to idle for a another 3 minutes. Drive the vehicle at constant speeds of approximately 30, 40, 50, 60 and 70 MPH for 3 minutes each. This may cause a driveability concern if the procedure is not carried out. This will allow the ECM to relearn idle values.
