Normalization:
If the systems battery is disconnected or dead, the following systems should be
checked for normal operation. If systems are inoperative or erratic then normalization
will have to be performed.
Potential systems requiring normalizing are:
• ESP
• AAC - automatic air conditioning
• Windows and sunroof
• Left front seat
• Right front seat
• Steering wheel and mirrors
Adding additional electric accessories:
When adding accessories always use a power supply that is fused through the
pre-fuse boxes. This will ensure that the BCM can monitor the current
consumption accurately.
DO NOT CONNECT ACCESSORIES DIRECTLY TO BATTERY TERMINALS
