Dodge Dakota (ND). Manual — part 106
C1035-REAR WHEEL SPEED COMPARATIVE PERFORMANCE (340) (CONTINUED)
For a complete wiring diagram Refer to Section 8W.
•
When Monitored:
With the ignition on, no system under voltage or over voltage condition present, no open or shorted wheel
speed sensor DTCs set, vehicle not under high acceleration, and vehicle speed greater than 0.
•
Set Condition:
This DTC will set if either one wheel is sensed above a predetermined range for 5000 msec while the other
wheels are below 20% of maximum velocity of all wheels OR if more than one wheel is sensed at below 20%
of maximum velocity of all wheels while at least one wheel is sensed above a predetermined range. The con-
dition must exist for 2 minutes for this DTC to set.
If the number of missing sensors changes at any update, the fault monitor is reset.
