ACCEL/Tap Function Inoperative

  1. Turn ignition off. Unplug 10-pin connector from servo. While pressing SET-ACCEL switch, measure resistance between servo harness connector pins No. 5 (Light Blue/Black wire) and No. 6 (Dark Green/Orange wire). Rotate steering wheel through full range while making measurement. If resistance is 646-714 ohms, switch is okay. Go to next step. If resistance is not 646-714 ohms, replace switch.
  2. Check for continuity between servo harness connector pins No. 6 (Dark Green/Orange wire) and No. 10 (Red/Light Blue wire). If continuity exists, repair switch ground circuit (Dark Green/Orange wire). If continuity does not exist, substitute known good servo assembly. Retest system.
