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. 11 (7.5 A) fuse in the auxiliary under-hood fuse/relay box
- An open or high resistance in the wire
1 WHT Disconnect gauge control module connector A (32P) Check for continuity between terminal No. 1 and gauge control module connector A (32P) terminal No. 12:
There should be continuity.An open in the UART wire Check for continuity to ground:
There should be no continuity.A short to ground in the UART wire
