Test 7A - Repairing Security Indicator Light Circuit

NOTE: For connector terminal identification, refer to CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see appropriate chassis wiring diagram in the WIRING DIAGRAMS article.

Turn ignition on. If security indicator light is constantly on, go to TEST 7B. If security light is not on constantly, disconnect VTA module. Connect jumper wire between security light control circuit terminal No. 17 (Black/Orange wire) of VTA module connector and vehicle ground.
If security light illuminates, replace VTA module. If security light does not illuminate, disconnect Mechanical Instrument Cluster (MIC) Natural color connector. Remove instrument cluster. See INSTRUMENT PANEL article in the ACCESSORIES/SAFETY EQUIPMENT section. Visually inspect condition of instrument cluster circuit board. Replace circuit board if damaged. Perform TEST VER-1 .
If circuit board is okay, inspect security indicator light bulb. Replace bulb if open (NG). Perform TEST VER-1 . If security indicator light bulb is good, check fused battery feed voltage at terminal No. 10 (Pink wire) of MIC Natural color connector.
If voltage is less than 10 volts, repair open fused battery feed circuit (Pink wire). Perform TEST VER-1 . If voltage is more than 10 volts, repair open security indicator light control (Black/Orange wire). Perform TEST VER-1 .
