Interactive Self-Test
- This test determines integrity of amplifier and will check to see if amplifier is receiving all inputs. As each switch is operated and each circuit input is received by amplifier, a code will be output (test light will flash). If test light flashes indicated code, circuit is okay.
- If code does not flash, malfunction is present. See INTERACTIVE SELF-TEST CODES table. To start Interactive Self-Test, locate amplifier secured to right side of steering column.
- Connect a 12 volt test light between Green/White wire terminal and open terminal of amplifier connector. See Fig 1 . Ensure ignition and cruise control are off. Turn ignition on.
- On automatic transmission models, move shift lever to DRIVE or REVERSE. Move cruise control switch to RESUME position and hold there. Turn ON/OFF switch to ON position. Release RESUME lever. System is now in Interactive Self-Test. If a repair is made, quick test should be repeated to verify repair.
