TITLE:
SRS Indicator On With No SRS DTC(s) Set

APPLIES TO:
1996-03 Accords, 1996-03 Civics, 2000-03 Insights, 1996-03 Odysseys, 2003 Pilots, 19960-1 Preludes, and 2000-03 S2000s.


SERVICE TIP:

If the SRS indicator comes on periodically, and you can't find any SRS DTC(s) that are set, check the alternator charge voltage the instant the indicator comes on. A bad voltage regulator can let the system voltage exceed the allowable voltage threshold of the SRS control unit.

To check for a bad voltage regulator, hook up a voltmeter to the battery or connect the PGM Tester to the 16P data link connector. Test-drive the vehicle at high rpm with various electrical loads turned on and off. Watch the voltmeter or, if you're using the PGM Tester, monitor BATTERY on the display. If the charge voltage is around 16 volts, replace the alternator.
