D - Air Bag Light Does Not Come "ON" Steady During Crank
TABLE D "AIR BAG" WARNING LAMP DOES NOT COME "ON" STEADY DURING CRANKCIRCUIT DESCRIPTION
When the ignition switch is first turned "ON," "Ignition 1" voltage is applied from the "C-21" fuse to "Redundant Indicator Ignition 1 ," terminal "B2", and to the "AIR BAG" warning lamp which is connected to "SRS Indicator," terminal "Bi". The "C-22.C-23" fuses applies system voltage to the "Ignition 1" inputs, terminals "A9" and"A1O". The DERM responds by flashing the "AIR BAG" warning lamp seven times.When the engine is being cranked, "Starter" voltage is applied from the "C-i" fuse to the DERM at the "Crank" input. The DERM responds by grounding the "SRS Indicator" output until "Starter" voltage is removed from the "Crank" input. This results in the "AIR BAG" warning lamp being "ON" during cranking.After cranking, the DERM will flash the "AIR BAG" warning lamp six times.
CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the diagnostic table.
1. This test checks for a proper signal to the "Crank" input during cranking.
2. This test determines whether the lack of a proper crank signal is due to an open "Crank" input circuit or an open power feed to the "C-i" fuse.
3. This test checks for an open in the Body Harness.
4. This test checks for an open in the SRS harness.
