SRS components are located in this area. Reviewthe SRS component locations (see page 23-'13) and precautions andprocedures (see page 23-14) in the SRS section before performing repairs or service.
1. Disconnect the 14P connector from the control unit.
2. Inspect the connector and socket terminals to be sure they are all making good contact.
. lf the terminals are bent, loose, orcorroded, repairthem as necessary, and recheckthe system.. lf the terminals look OK, go to step 3.

lf any test indicates a problem, find and correct the cause, then recheck the system. lf all the input tests prove OK,
the cruise control unit may be faulty. Substitute a known-good cruise control unit and retest. lf the system works
properly, replace the cruise control unit.

control actuator (B).
Remove the cover (A), and check the output linkage
(B) for smooth movement.

Connect battery power to the No, 2 terminal and
ground to the No. 1 terminal.
Check for a clicking sound from the magnetic clutch.
The output linkage should be locked.
lf the output linkage is not locked, replace the
