Checking IEGR wiring
1 NOTICE! Cut the current with the main switch.
2 Remove the valve cover.
3
Remove the connector from the IEGR solenoid.
4 Remove connector B from the EMS2.
5 Use multimeter 88890074 to do a resistance meas-
urement between connector B from the EMS2 to
the loosend connector.
Measurement points Nominal value
B30 – 1 (IEGR connector) R ≈ 0 Ω
B57 – 2 (IEGR connector) R ≈ 0 Ω
B60 – 2 (IEGR connector) R ≈ 0 Ω
B30 – 2 (IEGR connector) R ≈ ∞ Ω
B57 – 1 (IEGR connector) R ≈ ∞ Ω
B60 – 1 (IEGR connector) R ≈ ∞ Ω
IMPORTANT!
Be very
careful when measuring inside the connector,
to ensure that no pin is damaged.
Checking camshaft sensor wiring
Tools:
885675 Break-out cable
88890074 Multimeter
1 NOTICE! Cut the current with the main switch.
2 Remove the connector from the sensor. Connect
break-out cable 885675 to the connector.
3 Remove connector A from the EMS2.
4 Use multimeter 88890074 to do a resistance meas-
urement from the sensor connector to connector A
to verify that neither of the wires are broken or short
circuited.
Measurement points Nominal
value
1 (sensor conn.) – 38 (conn. A) R ≈ 0 Ω
2 (sensor conn.) – 37 (conn. A) R ≈ 0 Ω
1 (sensor conn.) – 2 (sensor conn.) R ≈ ∞ Ω
IMPORTANT!
Be very careful when measuring inside the connector,
to ensure that no pin is damaged.
