SHIFT POSITION INDICATOR CIRCUIT
Revision: June 20062007 Versa
SHIFT POSITION INDICATOR CIRCUITPFP:24810
DescriptionUCS006XM
TCM sends the switch signals to combination meter via CAN communication line. Then selector lever position
is indicated on the shift position indicator.
CONSULT-II Reference ValueUCS006XN
Diagnostic ProcedureUCS006XO
1. CHECK INPUT SIGNALS
With CONSULT-II
1. Start engine.
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II and read out the value of
“SLCT LVR POSI”.
3. Check that the following three positions or indicators are same.
–Actual position of the selector lever
–“SLCT LVR POSI” on CONSULT-II screen
–Shift position indicator in the combination meter
OK or NG
OK >>INSPECTION END
NG >> Check the following.
SHIFT POSITION INDICATOR SYMPTOM CHART
Item name Condition Display value
SLCT LVR POSIWhen setting selector lever to “N” or “P” positions. N · P
When setting selector lever to “R” position. R
When setting selector lever to “D” position. D
When setting selector lever to “2” position. 2
When setting selector lever to “1” position. 1
Items Presumed location of trouble
Actual position does not change.Park/neutral position (PNP) switch

Refer to AT- 9 7 , "DTC P0705 PARK/NEUTRAL POSITION
(PNP) SWITCH" .
A/T main system (Fail-safe function actuated)

Refer to AT- 8 2 , "SELF-DIAGNOSTIC RESULT MODE" and
AT- 9 0 , "
Diagnostic Procedure Without CONSULT-II" .
Shift position indicator in the combination meter does not indicate
any position.
Perform the self-diagnosis for A/T and the combination meter.

Refer to AT - 8 2 , "SELF-DIAGNOSTIC RESULT MODE" and DI-
5, "COMBINATION METERS" . Actual position changes, but the shift position indicator in the
combination 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.

Refer to DI-5, "COMBINATION METERS" .
