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.

Actuator Cable Adiustment
1. Check that the actuator cable {A) moves smoothly
with no binding or sticking.
2. Start the engine.
3. Measure the amount of movement of the output
linkage (B) until the engine speed starts to increase.
At first, the output linkage should be located at the
fully closed position (C). The free play (D) should be
3.7510.5 mm (0.1510.02 in,).
4. lf the free play is not within specs, loosenthe
locknut (E). and turn the adjusting nut (F) untilthe
free play is as specified, then retighten the locknut

NOTE:. To check the clutch pedal position switch(see page 4-45).. To check the clutch interlock switch (see page 4-6).. Remove the driver's side floor mat before adjusting
the clutch pedal.. The clutch is self-adjusting to compensate for wear.. lf there is no clearance betweenthe mastercylinderpiston and push rod, the release bearing will be held
against the diaphragm spring. which can result in
clutch slippage or other clutch problems.
1. Loosen the clutch pedal position switch locknut (A),
and back off the clutch pedal position switch (B)
until it no longer touches the clutch pedal (C).
