DESCRIPTION:

When system voltage is applied to the DERM it will perform "Turn-ON" tests followed by "Continuous Monitoring" tests. If no faults are detected, the DERM will perform a "Steering Column Resistance Test". When a fault is detected, the DERM will store a current code and illuminate the "INFL REST" warning lamp. The DERM will clear current codes (with the exception of code 51) when the fault is no longer detected or when the ignition switch is cycled. The code will then be stored as a history code until cleared.

TEST DESCRIPTION: Number(s) below refer to circled number(s) on the diagnostic chart.

14. Checks for intermittent open in the 36VLR Wiring CKT 236.

15. Checks for intermittent open between fuse #12 and the arming sensor CKT 1139.
