Test F: The Battery Saver Does Not Deactivate After Time-Out
PINPOINT TEST F: THE BATTERY SAVER DOES NOT DEACTIVATE AFTER TIME-OUT
Normal Operation
The instrument cluster (IC) energizes the battery saver relay located in the central junction box (CJB), through circuit 1005 (VT/OG). The battery
saver relay provides voltage to circuit 705 (LG/OG). Circuit 705 (LG/OG) provides voltage to all demand lamps. The demand lamps are grounded
through circuit 57 (BK). The battery saver deactivates when the IC releases the ground from the relay on circuit 1005 (VT/OG), after time-out. The
battery saver relay is integral to the CJB.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
CJB
-
IC
