SHIFT POSITION INDICATOR CIRCUIT
SHIFT POSITION INDICATOR CIRCUIT
DescriptionINFOID:0000000005397979
TCM sends the switch signals to combination meter vi
a CAN communication line. Then selector lever position
is indicated on the shift position indicator.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005397980
Diagnosis ProcedureINFOID:0000000005397981
1.CHECK INPUT SIGNALS
With CONSULT-III
1. Start engine.
2. Select “MAIN SIGNALS” in “DATA MONITOR” m ode for “TRANSMISSION” with CONSULT-III and read
out the value of “RANGE”.
3. Check that the following three pos itions or indicators are same.
- Actual position of the selector lever
- “RANGE” on CONSULT-III screen
- Shift position indicator in the combination meter
OK or NG
OK >> INSPECTION END
NG >> Check the following.

and DI-4
.
Actual position changes, but the shift position indicator in the com-
bination meter does not change.
Actual position differs from the shift position indicator in the com-
bination meter.
Shift position indicator in the combination meter does not indicate
specific position only.
Check the combination meter.
