Rogue Communication: SureTrack Community Fix

by Nick Taylor

Real Fixes from Mitchell 1’s SureTrack® expert information resource are documented issues from actual shop repair orders and community discussions. Read on to see how SureTrack can help you correct issues that are not easily diagnosed using OEM information alone. SureTrack is available at no additional cost in our ProDemand product.

Lack of communication with one or more modules in a vehicle can really slow down the diagnosis. SureTrack community member trannyman1 had a Nissan Rogue in the shop that wouldn’t drive and several codes. No communication with the TCM was the first problem. They posed the question to the community, and with the help of fellow community member Ericsautomotive and others, they were able to resolve the issue quickly.

The following Community Fix summarizes the interaction between members of the community that led to the solution.

Vehicle
2012 Nissan Rogue SV 2.5L

Title
Customer states that vehicle is not driveable.

Complaint
No communication with TCM, repaired wiring.

Diagnostic Steps Performed/Parts Replaced
Vehicle came in on the hook with no communication with the TCM and P1740, P0840, U1001, and U0101 codes in the ECM. I checked all powers and grounds to the TCM and they all load tested good. I checked pin fitment and all appeared good. I found a used TCM and installed. The codes cleared, and the TCM communicated. I pulled out of shop and started to drive it and the TCM stopped communicating and reset all of above codes. Next, I rechecked all powers and grounds, and checked resistance between CAN hi and CAN lo and it was 65 ohms. I scoped the CAN hi and CAN lo and had good square waves on both wires and they mirrored each other. I found that vehicle had an aftermarket remote start installed. I unplugged it from harness, still no communication. I checked CAN hi and CAN lo wiring between ECM and TCM and all appears good. I’m at a loss as what to check next other than another TCM? Any suggestions would be appreciated.

Best Answer from Community Member Ericsautomotive
I’ve seen a shorting solenoid take a TCM out on one of these.

Cause
I installed another used TCM and got communication. It then set P1740 and 840 codes as a hard fault. I checked the wiring harness for voltage drop and found the wires inside the harness between radiator and transmission were badly damaged inside the loom. There wasn’t any external damage?

Correction
Repaired wiring, Cleared the codes and drove it numerous times and all is well. Thanks for the responses.
