With GST

  1. Turn ignition switch ON.
  2. Check voltage between ECM terminal 102 (PNP switch signal) and ground under the following conditions.
    CHECKING VOLTAGE CONDITION

    Condition (Gear position) Voltage V (Known good data)
    P or N position Approx. 0
    Except the above position BATTERY VOLTAGE (11 - 14V)
  3. If NG, go to DIAGNOSTIC PROCEDURE .

Specification data are reference values and are measured between each terminal and ground.

CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
