Control Unit Input Test
l. Bemove the driver's dashboard lower cover and the knee bolster (see section 20).
2, Disconnect the 5P 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 orcorroded, repairthem 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.
