Reducing Agent (AdBlue(R)) Consumption or Quality Checking







Reducing Agent (AdBlue(R)) Consumption or Quality Checking

Observe all safety precautions: => [ Safety Precautions ] Safety Precautions

View clean working conditions: => [ Clean Working Conditions ] Clean Working Conditions

Prior to repair work, perform a preliminary check to verify the condition. Refer to => [ Preliminary Check ] Preliminary Check.

The AdBlue(R) (reducing agent) may irritate skin or eyes. If the fluid comes into contact with skin, rinse/flush the affected area immediately with plenty of water.

The AdBlue(R) can decompose if opened for extended periods, or stored near hot sources. Always store in cool dry place. Do not leave container opened for any extended period. Do not use if the fluid has a strong ammonia odor or has any crystallization formed inside the container, it is aged and should NOT be used as damage to the system could occur. AdBlue(R) is colorless and nearly odorless when in a fresh state.

Reducing agent quality check:

- Check the reducing agent in tank for staleness or aging. The filler cap is located under the spare tire in the rear cargo area. Remove the cap and look for signs of crystallization inside the tank or having a strong ammonia odor. If the reducing agent has gone stale (strong odor), drain the fluid from the tank and refill. If a heavy crystallization condition exists, the tank assembly should be removed and flushed with clean warm water and thoroughly drained. Dry completely as water will contaminate the reducing agent. Refill with fresh AdBlue(R).

Reducing agent quantity (consumption) check:

- The reducing agent consumption codes are rationality tests based on the reaction of the NOx sensors to an increase or decrease of the reducing injection amount. First, make sure the quality check was performed and the reducing agent is not diluted or stale. If any NOx sensor codes are set, refer to those procedures first.
