WARNING: This page is about a different variant/trim than selected.
NOTE:
Make all DVOM connections at component terminal rather than at cable or wire end.
- Disconnect the wiring from the fuel pump electrical connector. Connect remote starter switch between starter solenoid terminal "S" and positive battery post on passenger side. See Fig 1 .
- Connect positive DVOM lead to starter housing, and negative lead to negative battery post. Engage remote starter switch while observing DVOM. DVOM should indicate .2 volt or less. If DVOM indicates more than .2 volt, clean negative cable connections at battery and engine. Retest system.
- If voltage drop is still excessive, repair or replace appropriate negative battery cable and/or engine ground cable as necessary. Repeat starter ground circuit test after repair to ensure problem has been corrected.
NOTE:
Take reading at both negative battery posts individually. Record results from both negative posts.
