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

Idle 
condition is 
changed by 
stopping 
selected 
cylinder: 
this can 
cause an 
unstable 
condition 
and the 
engine may

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.
