CHECK AT THE ENGINE CONTROL MODULE (ECM)

M1131153502104

1. Disconnect the ECM connectors B-10 and B-11,

and connect check harness special tool
MB992110 between the ECM 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: *

: The average voltage through an analog

voltmeter is described in this service manual
(because the average voltage would be not con-
stantly shown on a digital voltmeter).

NOTE: *

: Vehicles for Canada, the headlight, tail-

light, etc. remain lit even when the lighting switch is
in "OFF" position but is no problem for checks.
