7. Raise the front of the vehicle, and make sure it is
securely supported.
8. Set the parking brake, and block the rear wheels
securely.
9. Start the engine, cancel the TCS, then shift to 2
position, and drive for more than 5 seconds.
10. Measure the voltage PCM connector terminals C11
and A25 or A26.
Check for loose terminal fit in the PCM
connectors. If necessary, substitute a known-good
PCM and recheck.
Go to step 11.
11. Turn the ignition switch OFF.
12. Disconnect the 2nd clutch pressure switch
connector.
13. Turn the ignition switch ON (II).
14. Measure the voltage between the 2nd clutch
pressure switch connector terminal and body
ground.
Go to step 15.
Repair open in the wire between the 2nd
clutch pressure switch and the PCM.
15. Measure the resistance between the 2nd clutch
pressure switch connector terminal and body
ground.
Check for loose terminal fit in the PCM
connectors. If necessary, substitute a known-good
PCM and recheck.
Replace the 2nd clutch pressure switch (see
page 14-135).
