(5) Measure the voltage between terminal 61 and ground.
• The voltage should measure below battery positive volt-
age.
(6) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?
YES : Go to Step 11.
NO : Go to Step 15.
STEP 15. Check PCM connector B-21 for loose, corroded
or damaged terminals, or terminals pushed back in the
connector.
Q: Are the connector and terminals in good condition?

STEP 17. Check the transmission range switch.
Measure the resistance between the terminals for each trans-
mission range as indicated in the table below.
NOTE: For vehicles with sport mode, four positions (P, R, N, D)
are used.
Q: Is the measured resistance less than 2 ohms for each
transmission range?
YES : Go to Step 18.
NO : Replace the transmission range switch. Refer to
