F SELF-DIAGNOSIS FUNCTION
SELF-DIAGNOSIS FUNCTION
DESCRIPTION
The engine control unit (integrated with the EC-AT control unit) has built-in Self-Diagnosis function the same
as for the previous models. When trouble occurs in the main input devices or output devices, they are indi-
cated and retrieved from the engine control unit (ECU) as service code numbers.
When inspecting for service code(s) memorized in the ECU use the Self-Diagnosis checker and system selector
(SST).
Note
l The ECU constantly checks for malfunction of the in put devices. But, the ECU checks for
malfunction of output devices only in a three second period after the ignition switch is turned
ON and the TEN terminal of the diagnosis connector is grounded.

* After repairing a problem, turn the ignition switch OFF and disconnect the negative battery
cable at least 20 seconds to erase the service code numbers from the engine control unit (ECU)
memory.
