Scoupe L4-1468cc 1.5L SOHC VIN J MFI (1994)
1.
Place auto lash adjuster in special service tool 09246-32300 as shown illlustrated.
2.
After the plunger has fallen 0.2. 0.5 mm (0.008 - 0.02 in), measure the subsequent falldown rate.
3.
The standard fall-down rate is 2.5 mm in 20 - 50 seconds. If the fall-down rate is out of specification, replace the auto lash adjuster.
Ignition System
Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data for the engine operation
conditions are mapped in the memory of the engine control module (ECM).
The engine conditions are detected by various sensors. Based upon these sensors and the ignition timing data, signals to interrupt the primary current are
sent by the ECM to the power transistor. Ignition timing is controlled in this manner.
Circuit Operation
When the power transistor in the ECM sends a signal to the ignition coil, the primary current is shut off and a high voltage is induced in the secondary
