Safety measures
Consider the following in order to avoid personal injury and/or deterioration of the injection and ignition systems:
t  Do not touch or disconnect the ignition cables with the engine running or starting.
t  Disconnect and connect injection and ignition system cables, including the measuring equipment, only with ignition off.
If during a test cycle, it is necessary to use test and measuring equipment, consider the following:
t  Always install test and measuring equipment on the rear seat and have them operated by a second repairer.
If test and measuring equipment are operated from the passenger seat, the person seated there may be injured should the airbag activate in case of accident.

–  Disconnect the 4-pole connector from the Ignition transformer -N152--arrow-.
