up, idle. (cut the
fuel supply to
each injector in
turn and check
cylinders which
don't affect
idling)

condition is
changed by

CHECK AT THE ENGINE CONTROL MODULE (ECM)

M1131153502342

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. 81 or No. 93).

TERMINAL VOLTAGE CHECK CHART

NOTE: *

1

: The average voltage through an analog voltmeter is described in this service manual (because the

average voltage would be not constantly shown on a digital voltmeter).
NOTE: *

2

: Vehicles for Canada, the headlight, taillight, etc. remain lit even when the lighting switch is in "OFF"

position but is no problem for checks.
NOTE:

*

3: If the battery is fully charged, the output reading may be incorrect.
