Chart F, Inflatable Restraint Indicator Flashes 7 Times, Then Flashes Code 12: Description
WARNING: This page is about a different car, the 1991 Geo Storm, 1991 Geo Metro, 1990 Geo Storm, and 1990 Geo Metro. However, it is still accessible from the selected car via links, so may be relevant.
When ignition switch is first turned on, system voltage is applied through METER fuse to SIR INDICATOR HIGH B9 and to INFLATABLE RESTRAINT indicator light, which is connected to SIR INDICATOR LOW A1. SIR fuse also applies system voltage to IGNITION 1 inputs A3 and B3. DERM responds by flashing INFLATABLE RESTRAINT indicator light 7 times.
When engine is cranked, system voltage is applied to DERM at CRANK input. DERM grounds lamp circuit until system voltage is removed from CRANK input. This results in a steady INFLATABLE RESTRAINT indicator light during cranking.
After cranking, DERM will again flash INFLATABLE RESTRAINT indicator light 7 times if ignition switch is on.
NOTE:
Test numbers refer to test numbers on diagnostic chart. For circuit number identification, see WIRING DIAGRAMS
.
- Checks DIAGNOSTIC REQUEST circuit for voltage at ALDL connector.
- Checks if short to ground is in DIAGNOSTIC REQUEST circuit or DERM.
