FRONT CYLINDER HV COIL CONNECTOR
1. Injection load relay (Black-Green)
2. Control unit (Sky Blue)
H.V. COIL
Primary winding resistance: 520 ÷ 620 mOhm
Secondary resistance: 6830 ÷ 7830 Ohm
Check if there is voltage for 2 seconds, switching to "ON" between pin 1 of the coil connectors and
ground lead.
Check the continuity between pin 2 of the cylinder 1 coil connector and pin 38 of the engine connector
control unit.
Check the continuity between pin 2 of the cylinder 2 coil connector and pin 10 of the engine connector
control unit.
Inspecting the spark plug shielded cap
Measure the shielded cap resistance.
Electric characteristic
Resistance:
5 KΩ
If different values are measured (<1; >20KΩ), replace the shielded cap.
N.B.
A SHIELDLESS CAP OR SPARK PLUG CAN ADVERSELY AFFECT THE INJECTION SYSTEM.
FOR INFORMATION ON THE SPARK PLUG, SEE THE «SPECIFICATIONS» AND «MAINTE-
NANCE» CHAPTERS.
Spark advance
The ignition advance is determined electronically on the basis of parameters known by the control unit.
For this reason it is not possible to declare the reference values based on the engine rpm.
The ignition timing value is detectable any time using the diagnostic tester.
