Pinout Values and Diagnostic Parameters

CHECK AT THE ENGINE CONTROL MODULE (ECU) [M/T] OR THE POWERTRAIN CONTROL MODULE (PCM) [A/T]

1. Disconnect the ECM [M/T] or the PCM [A/T] connectors B-18 B-19 B-20 B-21 and B-22 and connect check harness special tool MB991923 between the ECM [M/T] connectors or the PCM [A/T] connectors.
2. Measure the voltage between each check harness connector terminal and check harness connector ground terminal (No.25 or No.29).

TERMINAL VOLTAGE CHECK CHART

NOTE:
*1: The average voltage through an analog voltmeter is described in this service manual (because the average voltage is too stable to be shown on a digital voltmeter).
*2: Vehicles for Canada, the headlight, taillight, etc. remain lit even when the lighting switch is in "OFF" position but this is no problem for checks.
