NOTE:
. Clean the areas where the driveshafts contact the
transmission (differential) thoroughly with sol-
vent or carburetor cleaner, and dry with com-
pressed air.
. Turn the right and left steering knuckle fully out-
ward, and slide each driveshaft into the differen-

Troubleshooting Procedures
(cont'd)
C. lf the inspection for a particular code requires voltage or resistance checks at the TCM or PCM connectors, removethe driver's side kick panel, and unbolt the TCM, and at the PCM connectors, remove the passenger's side kickpanel, and unbolt the PCM. Turn the ignition switch OFF, and connect the backprobe sets and a digital multimeteras described below. Check the system according to the procedure described for the appropriate code(s) listed onthe following pages.
