Diamante Sedan V6-3.5L SOHC (1999)
Standard wave pattern
Wave Pattern Observation Points
Point: Condition of wave pattern build-up section and maximum voltage (Refer to abnormal wave pattern examples 1 and 2.)
Examples of Abnormal Wave Patterns
-
Example 1
Wave pattern during engine cranking
CAUSE OF PROBLEM
Open-circuit in ignition primary circuit
WAVE PATTERN CHARACTERISTICS
Top-right part of the build-up section cannot be seen, and voltage value is approximately 2 V too low.
-
Example 2
Wave pattern during engine cranking
CAUSE OF PROBLEM
Malfunction in ignition power transistor
WAVE PATTERN CHARACTERISTICS
Power voltage results when the ignition power transistor is ON.
