LeSabre V6-231 3.8L VIN L SFI (1992)
DIAGNOSTIC AIDS:
While observing knock signal on the "Scan," there should be an indication that knock is present when detonation can be heard. Detonation is most likely
to occur under high engine load conditions.
NOTE: If the ESC circuit is routed to close to the secondary ignition wires, induced voltage may cause a false knock signal.
