Refer to the CAN protocol
document as published on the
Dana TM4 extranet site
Disconnect the VMU
interface harness
connector from the MCU.
Does the Device communicating
with the MCU comply with the CAN
protocol document used for the MCU,
including shutdown sequence ?
Set the CAN protocol
of the device
communicating with
the MCU.
No
Yes
Inspect the VMU
interface connector
integrity of the MCU.
Is there
any evidence of an
integrity loss on VMU/
ECU interface
connector on
MCU ?
Refer to the
Verify
Connector Integrity
subtree (STT01).
With a multimeter in resistance mode, measure the
resistance between the CAN High and CAN Low and
between CAN high and chassis and CAN low and
chassis for each CAN inputs ports of the VMU/ECU
interface connector of the MCU :
Connector type 1
CAN 1 low (pin
A
) to CAN 1 high (pin
B
)
CAN 2 low (pin
C
) to CAN 2 high (pin
D
)
CAN 1 low (pin
A
) to Ground
CAN 1 high (pin
B
) to Ground
CAN 2 low (pin
C
) to Ground
CAN 2 high (pin
D
) to Ground
Connector type 2
CAN 1 low (pin
9
) to CAN 1 high (pin
16
)
CAN 2 low (pin
2
) to CAN 2 high (pin
10
)
CAN 1 low (pin
9
) to Ground
CAN 1 high (pin
16
) to Ground
CAN 2 low (pin
2
) to Ground
CAN 2 high (pin
10
) to Ground
Are
all measurements
comply with the « CAN
port measurements »
table ?
No
No
A
With a multimeter in resistance mode, measure
the resistance between CAN High and CAN Low
and between CAN high and chassis and CAN low
and chassis for each CAN pins of the VMU/ECU
interface harness :
Connector type 1
CAN 1 low (pin
A
) to CAN 1 high (pin
B
)
CAN 2 low (pin
C
) to CAN 2 high (pin
D
)
CAN 1 low (pin
A
) to Ground
CAN 1 high (pin
B
) to Ground
CAN 2 low (pin
C
) to Ground
CAN 2 high (pin
D
) to Ground
Connector type 2
CAN 1 low (pin
9
) to CAN 1 high (pin
16
)
CAN 2 low (pin
2
) to CAN 2 high (pin
10
)
CAN 1 low (pin
9
) to Ground
CAN 1 high (pin
16
) to Ground
CAN 2 low (pin
2
) to Ground
CAN 2 high (pin
10
) to Ground
Yes
Switch OFF the auxiliary
batteries switch.
