Engine Control Module (System Overview): Description and Operation (page 27 of 42) – Volvo XC90 AWD L6-2.9L Turbo VIN 91 B6294T (2004)

The emissions warning lamp in the Driver Information Module (DIM) has a warning symbol. This warning symbol varies depending on the market and
model year. The warning symbols are:

-

"Engine symbol" (not USA, model year 2001-)

-

"CHECK ENGINE" (MIL - Malfunction Indicator Lamp, USA only).

-

"Lambda symbol" (not USA, model year 1999-2000).

The warning symbol lights when the ignition key is turned to position II and goes out when the engine is started if the engine management system does
not detect any faults.
The warning lamp is directly connected to the engine control module (ECM).
The warning lamp will light if there is a fault in one of the parameters in the engine management system. The warning lamp will also light in response to
a request transmitted via the Control area network (CAN) if there is a fault in one of the following systems which affects emissions:

-

transmission control module (TCM)

-

brake control module (BCM).
