1333The ADC line is short-circuited to
GND.Ð
NOTE:
The on/off signal line of the shift on the fly system is
short±circuited to GND.The system enters into the fail-safe mode because of
fusing or system protection.
(If a short±circuit is observed on GND, the output to
the on/off signal line becomes 0V.)

Trouble Diagnosis Depending on The
Status of TOD Indicator
Functional check with TOD indicator light is conducted
prior to check on Charts A±H.
After the starter is switched on, check and see if the
status has become as tabulated below.
C07RW012
If the status is as tabulated above, there is no
problem. If not as tabulated above, inspect the
harness.
