MID 144 SID 250 SAE
J1587/1708 Information Link,
Check
Special tools: J-39200
NOTE!
•
Read off the other fault codes for the VECU.
•
Check the particular connectors during the fault
tracing for oxidation and switch resistance. For
detailed circuit information, refer to “VNL, VNM Elec-
trical Schematics,” Group 37.
Appropriate Tests in the VCADS
Pro Tool
The following test(s) are useful for closely examining the
component’s function:
N/A
No test currently available.
Check of Subsystem
1
Turn the ignition key to the ON posi-
tion.
2
Using a voltmeter, back the probe
connector PC (Green, 5–pin) at con-
nectors PC1 and PC2 with the
connector installed in the VECU.
Note: This may require the use of volt-
meter function MIN/MAX.
Measuring points
Expected value
PC1 / Alternate ground
0-5 V DC
PC2 / Alternate ground
0-5 V DC
PC1 / PC2
2-5 V DC
Note: The voltage of the information
link varies and is dependent on the
number of electronic control units and
traffic on the information link.
