11) With ignition switch OFF, disconnect contact
coil connector located near the base of the
steering column.
2) Check proper connection to contact coil at
terminals in ªCº connector.
3) If OK then connect Special Tool (B) to contact
coil connector disconnected at step 1).
4) With ignition switch ON, is DTC 21 current?Go to step 2.Go to step 3 on the
next page.
21) With ignition switch OFF, disconnect SDM.
2) Check proper connection to SDM at terminals
ªA6º and ªA7º.
3) Release shorting bar in SDM connector,
referring to the figure below.
4) If OK then measure resistance between ªA6º
and ªA7º terminals with connected Special Tool
(B).
5) Is resistance 3.5 or less?Substitute a known-
good SDM and
recheck.Repair high resistance
or open in ªGº or ªG/Rº
wire circuit.
