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.

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
