DTC Confirmation Test (Using Generic Scan Tool)

NOTE: Use the following test to check overall function of PNP switch circuit. During this test, DTC may not be confirmed.
CAUTION: DO NOT use ECM ground terminals when measuring voltage.
  1. Turn ignition on. Backprobbing at ECM, measure voltage between body ground and ECM terminal No. 44 (Blue wire) PNP switch signal circuit. See Figure and Figure .
  2. With transmission in Park or Neutral, voltage should be about zero volts. With transmission in any other position, battery voltage should exist. If voltage is as specified, system is okay at this time. If voltage is not as specified, go to DIAGNOSTIC PROCEDURE .
