STEP 9. Measure the switch output voltage at PCM
connector C-92 by backprobing. ("R" position)

Measure the voltage between terminal 108 and ground by
backprobing.

• When transmission range is "P", voltage should measure

0.5 volt or less.

• When transmission range is "R", voltage should measure

battery positive voltage.

• When transmission range is "N", voltage should measure

0.5 volt or less.

• When transmission range is "D", voltage should measure

0.5 volt or less.

• When transmission range is "3", voltage should measure

0.5 volt or less.

• When transmission range is "2", voltage should measure

0.5 volt or less.

• When transmission range is "L", voltage should measure

0.5 volt or less.

Q: Is the measured voltage within the specified range?

YES : Go to Step 14.
NO : Turn the ignition switch to the "LOCK" (OFF) position.

Go to Step 10.

STEP 10. Check intermediate connector C-96 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q: Are the connector and terminals in good condition?

YES : Go to Step 11.
NO : Repair or replace the damaged components. Refer to
