- Disconnect the battery or batteries. Refer to Battery Disconnect
.WARNING: Battery acid and battery acid fumes are extremely dangerous and can cause severe burns and explosion. To help reduce the risk of personal injury:
- Wear appropriate goggles and protective clothing.
- Always properly ventilate the area where the service is being performed.
- Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces.
- To avoid arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last.
- If acid contacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.
- Remove the DOC and DPF assembly. Refer to Removal and Installation .
- Loosen the DPF differential pressure sensor tube nuts.WARNING: During regeneration, exhaust gas temperature could reach 800°C (1500°F), and exhaust system surface temperature could exceed 700°C (1300°F), which is hot enough to ignite or melt common materials, and to burn people. The exhaust and exhaust components can remain hot after the vehicle has stopped moving. To avoid the risk of fire, property damage, burns or other serious personal injury, allow the exhaust system to cool before beginning this procedure or repair and make sure that no combustible materials are located where they are likely to come in contact with hot exhaust or exhaust components.CAUTION: To avoid possible damage or performance issues with the Diesel Particulate Filter (DPF) differential sensor:
- Ensure the DPF tubes are connected to the correct port.
- Ensure the DPF tubes slope downward to drain condensation away from the DPF differential pressure sensor.
- Remove the quick-disconnect fittings (A) from the DPF differential pressure sensor (1) and remove the DPF differential pressure sensor tubes (2).
