Conformity check

INSTRUCTIONS

Only carry out this conformity check after a complete check with the diagnostic tool (reading of faults and verification of configurations).

Application conditions: engine off with ignition on (12 V battery supply), AIR CONDITIONING OFF (passenger compartment HVAC unit stopped and air conditioning compressor not engaged).

NOTE: To check that the temperature parameters are consistent (without a thermometer), simply read these parameters when the vehicle is cold (in the morning). The temperatures should be almost equal (interior, exterior and engine coolant).

The diagnostics of the states, parameters and commands listed in this check are interpreted in the technical notes for the ECU supplying the information (see the preliminaries chapter).

Sub-function: cold loop
