GO TO point 24
28 - If connections are conform and the fuse is
burnt, proceed as follows: Disconnect the follow-
ing connectors:
- Air injection
- Fuel injection
- H.V. core.
- Voltage adjuster
GO TO point 29
29 - Remove the burnt fuse. Check the mass insu-
lation of the pin 15 supply line
1 - 15 = Ohm infinite
YES point 31NO point 30
30 - Restore the wiring insulation.
GO TO point 29
31 - Connect the specific tool to the ECU. Mount a
new 20A fuse. Check the presence of battery volt-
age between pin 15 and pin 1 ( the fuse does not
burn)
1 - 15 = V battery
YES point 33 NO point 32
32- The fuse is again burnt. Check the wiring more
accurately and, if necessary, replace the ECU.
GO TO point 31
33- Make a good visual check of the wiring to avoid
