Indicator Input Test
SRS c o m p o n e n t s are located in this area. Review the SRS component locations, precautions, and procedures in the
SRS section before p e r f o r m i n g repairs or service (see page 23-28).
1. Remove the instrument panel (see page 20-84).
2. Remove the gauge assembly f r o m the dashboard (see page 22-68), then disconnect the gauge assembly B (22P)
and C (16P) connectors.
3. Inspect the connectors and connector terminals to be sure they are all making g o o d contact.
• If the terminals are bent, loose, or corroded, repair t h e m as necessary, and recheck the system.
• If the terminals look OK, make the f o l l o w i n g input tests at the gauge assembly B (22P) and C (16P) connectors.
- If a test indicates a p r o b l e m , find a correct the cause, then recheck the s y s t e m .
- If all the input tests prove OK, but the indicator is faulty, replace the printed circuit board.
