SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRSsection {24) before performing repairs or service.
1. Remove the driver's dashboard lower cover and knee bolster (see section 20),
2. Disconnect the 10P connector from the integrated control unit.
3. Remove the integrated control unit from the under,dash fuse/relay box.
4. lnspect the connector and socket terminals to be sure they are all makjng good contact.
. lf the terminals are bent, loose or corroded, repair them as necessary, and recheck the system..lftheterminalslookOK,makethefollowinginputtestsattheconnectorandthefuse/relayboxsocket.
- lf any test indicates a problem, find and correct the cause, then recheck the system.- lf all the input tests prove OK, the control unit must be faulty; replace it.

Disconnect the connectors from the daytime run-
ning lights control unit.
Inspect the connector and socket terminals to be
sure they are all making good contact.
lf the terminals are bent, loose or corroded. repair
them as necessary, and recheck the system.
lf the terminals look OK, make the following
input tests at the connector,- lf any test indicates a problem, find and correct
the cause, then recheck the system.- lf all the input tests prove OK, the control unit
must be faulty; replace it.
