Subsystem: passenger compartment ventilation
NOTESOnly carry out this conformity check after a full check with the diagnostic tool (fault
reading and configuration checks).
Test conditions: ignition on (12
volts APC), engine stopped, AIR CONDITIONING
SWITCHED OFF (passenger compartment blower switched off and air conditioning
compressor not engaged).
NOTE: To check that the temperature parameters are correct (without a thermometer),
read these parameters when the vehicle is cold (in the morning). The temperatures
should be approximately equal (interior, exterior and engine coolant). Fault finding
procedures for the statuses, parameters and commands listed in this check are
explained in the Technical Notes relating to the computer which generates the signal
(see the Introduction section).
