What causes a c0327 4WD trouble code?
A C0327 4WD trouble code relates to the transfer case shift motor and can caused by any of the following: What is a transfer case motor? 4HI and 4LO. The motor is equipped with an analog sensor that signals back to the transfer case shift control module (TCCM) whether it has actually completed the commanded shift properly.
How does the TCCM work on a c0327 4WD?
The transfer case motor mounts to the transfer case and engages with the transfer case sector shaft. The TCCM provides a 5-volt reference signal and a low reference circuit (like a ground but with a set voltage drop).
Can a DTC c0327 be duplicated in any position?
If DTC C0327 can be duplicated in any position, check the scan tool data for the Encoder Signal Voltage going high or low. If the Encoder Signal Voltage is going high, check the Encoder Low Reference circuit for an open or high resistance.
What to do when DTC c0327 4WD Lite sets?
If the encoder Signal Voltage is going low, check the 5 Volt Reference and Encoder Signal circuits for an open or high resistance. Check the C151 connector on the left fenderwell for possible poor connection. If DTC C0327 sets when making a shift into 4 HIGH only or during a slip event in auto 4WD, inspect the Transfer Case fluid for contamination.
What’s the c0327 code on my truck?
It’s throwing a c0327 code. I bought this truck with the problem and I can’t figure it out. So this is what happens when I start my truck the lights on the 4wd all light up then they all go out then the 4wd service light comes on. So I replaced the switch on the dash, the TCCM (transfer case shift module) and transfer case shift motor.
