Ford Mustang (1999-2004) Service Manual: Exhaust System (Description and Operation)
WARNING: The normal operating temperature of the exhaust system is very high. Never attempt to repair any part of the system until it has cooled. Be especially careful when working around the three way catalytic converter. The temperature of the three way catalytic converter rises to a high level after only a few minutes of engine operation.
CAUTION: When repairing exhaust system or removing exhaust components, disconnect all heated oxygen sensors (HO2S) at the wiring connectors to prevent damage to the heated oxygen sensors and wiring harness. For additional information, refer to Section for location of the heated oxygen sensors.
The exhaust system:
- contains dual three-way catalytic converters.
- has a crossover pipe downstream of the three way catalytic converters (4.6L).
- has two upstream heated oxygen sensors mounted before the three-way catalytic converters.
- the production muffler and tailpipe assembly is a one-piece design exhaust system.

Pinpoint Test E: LFC 15/DTC B1916 - Driver Air Bag Circuit Shorted to
Battery or Ignition
Normal Operation
The restraints control module (RCM) checks for driver air bag circuit
shorts to battery or ignition by
monitoring the voltage of circuit 614 (GY/OG) and 615 (GY/WH) at pins 3 and
4. If the RCM detects a
short to battery or ignition on e ...
Pinpoint Test K: LFC 35/DTC B1935 - Passenger Air Bag Circuit Resistance
Low
Normal Operation
The restraints control module (RCM) monitors the resistance of the
passenger air bag ignitor by
measuring the resistance between pins 6 and 7. If the RCM detects low
resistance between these
pins, it will store a diagnostic trouble code ...
