(4) Measure the voltage between joint connector (CAN2)
terminal 19 and body ground.
OK: 4.7 volts or less
Q: Do all the voltages measure 4.7 volts or less?
YES : Go to Step 4.
NO : Go to Step 12.

(1) Disconnect joint connector (CAN3), and measure the
voltage at the wiring harness side of joint connector
(CAN3).
(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN3)
terminal 6 and body ground.
OK: 4.7 volts or less
(4) Measure the voltage between joint connector (CAN3)
terminal 19 and body ground.
OK: 4.7 volts or less
Q: Do all the voltages measure 4.7 volts or less?
YES <M/T> : Go to Step 5.
YES <TC-SST> : Go to Step 6.
NO : Go to Step 13.

STEP 5. Check the wiring harness between joint connector
(CAN3) C-127 and ECM connector B-10 <M/T> for a short to
power supply. Measure the voltage at joint connector
(CAN3) C-127.
(1) Disconnect joint connector (CAN3), and measure the
voltage at the wiring harness side of joint connector
(CAN3).
(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN3)
terminal 4 and body ground.
OK: 4.7 volts or less
(4) Measure the voltage between joint connector (CAN3)
terminal 15 and body ground.
OK: 4.7 volts or less
Q: Do all the voltages measure 4.7 volts or less?
YES : Check intermediate connector C-131, and repair if
necessary. If the intermediate connector is in good
condition, repair the wiring harness between joint
connector (CAN2) C-104 and joint connector (CAN3)
C-127.
NO : Go to Step 14.
STEP 6. Check the wiring harness between joint connector
(CAN3) C-127 and shift lever connector C-27 for a short to
power supply. Measure the voltage at joint connector
(CAN3) C-127.
(1) Disconnect joint connector (CAN3), and measure the
voltage at the wiring harness side of joint connector
(CAN3).
(2) Turn the ignition switch to the ON position.
(3) Measure the voltage between joint connector (CAN3)
terminal 7 and body ground.
OK: 4.7 volts or less
