DTC 16 - Passenger Initiator Circuit Resistance Low: Description

During INITIATOR ASSEMBLY RESISTANCE TEST, DERM grounds DRIVER-SIDE LOW terminal B8 and turns on passenger current source at PASSENGER-SIDE HIGH terminal A7. This causes a known amount of current to flow through passenger initiator circuit. By monitoring difference between voltage at PASSENGER-SIDE HIGH terminal A7 and PASSENGER-SIDE LOW terminal B7, DERM calculates combined resistance of passenger inflator module, passenger inflator module jumper, harness wiring circuits No. 1403A and 348B, and connector terminal contact.
