Cruise Control
Gontrol Unit Input Test
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 l4P connector from the control unit.
3. 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 inpul tests at the connecror.- 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.
