Refer to Section 417-01, for Sun Load Sensor Pinpoint Test.
NOTE:
Activation of the battery saver supply (J3/3, refer Section

the ignition on and the battery saver supply active, the BEM reads the
signals from the sensor. The BEM transmits the sunload data over the
CAN bus to the climate control module. This sensor also controls the
Auto Headlight on function. Refer to Auto Headlight section.
NOTE:
DTC’s will not be available for invalid data signalled with the
ignition switch in either the accessories or the start position. The
output voltage from the sunload sensor is available at pin (J2/1. refer
section 419-10), it is in the range of five to zero volts.
