Interlock System
Interlock Control Unit Input Test
SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS
section (24) before performing repairs or service.
'1. Remove the instrument panel lower cover (see section 20).
2. Disconnect the 8P connector from the interlock control unit.
3. Inspect the connector and connector 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 a test indicates a problem, find and correct the cause, then recheck the system
- lf all the input tests prove OK, substitute a known-good control unit, and recheck the system. lf the check is OK,
the control unit must be faulty; replace it.
NOTE: lf the shift lock solenoid clicks when the ign ition switch is tu rned ON (ll) while pressing the brake pedal withthe
shift lever in E position, the shift lock system is OK. lf the shift lever cannot be shifted from E position. test the A/T
gear position switch.
