DIAGNOSTICS SFI SYSTEM (2AZ−FSE)
AVENSIS Supplement (RM 1045E)
S If communication is still impossible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.
4. INSPECT BATTERY VOLTAGE Battery voltage: 11 to14V
If voltage is below 11 V, recharge the battery before proceeding.
5. CHECK CHK ENG
(a) The CHK ENG c om es on when t he ignit ion swit ch is turned to ON and the engine is not running.
HINT:
If the CHK ENG is not illuminated, troubleshoot the CHK ENG
circuit (see page 05 −25 1).
(b) When the engine is started, the CHK ENG should not illu- minate. If the lamp remains on, the diagnosis system has
detected a malfunction or abnormality in the system.
