The smaller air
fuel ratio, the rich
return. The more

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: *
1
: 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: *
2
: 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.
