NOTE:
AIC valve receives a signal from transmission range switch. DRIVE light will glow if system is working properly.
- If system is not working properly, check fuse No. 13 on 900 Series or fuse No. 9 on 9000 Series.
- With ignition on, check for battery voltage at White wire at switch, located at base of transmission selector lever. If no voltage is present, repair White wire back to fuse panel.
- Set transmission selector lever, in turn, to PARK and NEUTRAL positions. With ignition on, ensure no voltage appears at Orange wire on switch with lever in either position. With lever in all other positions, battery voltage should appear at Orange wire. If voltage is as specified, go to next step. Replace switch if it does not meet specification.
- Connect DVOM to pin No. 30 (Orange wire) at fuel injection ECU. Battery voltage should appear with switch in all positions but Park or Neutral. Repair Orange wire between switch and ECU if voltage does not appear.
