Battery Sensor Input Test

NOTE: Before testing, make sure the battery ground cable is installed correctly, and make sure there is continuity between the battery negative terminal and ground terminal G1.

Disconnect the 2P connector (A) from the battery sensor (B).

Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
- If the terminals look OK, go to step 3.

With the 2P connector still disconnected, do the following input tests.

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, replace the battery sensor.

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
2	ORN	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. 12 (7.5 A) fuse in the under-hood fuse/relay box An open or high resistance in the wire
1	LT BLU	Disconnect the gauge control module 32P connector	Check for continuity between terminal No. 1 and gauge control module 32P connector terminal No. 12: There should be continuity.	An open in the UART wire
