The section between included a few other failure points including connectors 237 & 145 as well as splices 234 & 236. With some highlighters, I mapped out all the communication codes visually between modules on my communication network wire schematic.Īs you can see from above, my issue is most likely between splices 312 & 313 and splices 129 & 131. With some highlighters, I mapped out all the communication codes between modules on my CAN communication network wire schematic. A list of trouble codes can be hard to wrap your head around so I found a way to visualize them for this job. I also looked for common or shared module powers and grounds. My next step was the most important process I did to diagnose this truck. Looking at the CAN communication network wire schematic, I noted all common wire connectors, splices, and junctions. Since this vehicle’s issues were not present, I started to do a process of elimination.

U0115 – Lost Communication With ECM/PCM.

U0121 – Lost Communication With ABS Control Module.

U0253 – Lost Communication With Accessory Protocol Interface Module.

U0100 – Lost Communication With ECM/PCM.

U0155 – Lost Communication With Instrument Panel Cluster (IPC) Control Module.

U0151 – Lost Communication With Restraints Control Module.

During a few long test drives, the cluster would momentarily reset but the failure never lasted long enough to test the data bus. The only damage that was present was on the side mirror. This includes structural, modules, and wire harnesses. My next step included a visual inspection looking for any damage caused by falling from a hoist. This can be very helpful during the failure to know which modules I could communicate with before. By doing this now, it will confirm all the modules that are present with this truck and also confirms my scan tool has the capability to communicate with all of them. This made it an ideal time to check which modules I am able to communicate with as well. The customers concerns were not present while I was scanning for codes. It appears all the modules are pointing fingers at each other. This Ford had all the codes listed below, which you can see are all network “U” codes. The no-start can happen multiple times a day to once a week. The cluster issue is random while driving and can last for a fraction of a second up to 40 minutes.Īlmost always my first step in a diagnosis is to scan all modules for codes. Another concern is while driving, the dash gauges (cluster) will all go dead, malfunction lights come on, and error messages will display on the dash LCD panel. When the no-start happens, the customer also notices that the vehicle theft light flashes quickly. Turn the key to the OFF position and remove the key.Ĩ.Vehicle was dropped from a hoist and now has a intermittent no-start. Turn the key to the ON position for 6 seconds.ħ. Turn the key to the OFF position and disconnect the scan tool.Ħ.

If only the ECU was replaced, go to Step 9.įrom the scan tool, select: Ignition Key Code Erase and follow the on-screen instructions.ĥ. Make sure you have at least 2 vehicle keys, prior to carrying out the Immobilser parameter reset.

NOTE: If the Instrument cluster or the Intrument cluster and the ECU were replaced, updated or reconfigured, follow Steps 4-9.Īll vehicle keys are erased during the parameter reset procedure. From the scan tool, select: Parameter Reset and follow the on-screen instructions.Ĥ.

From the scan tool, follow the on-screen instructions to ENTER SECURITY ACCESS.ģ. Turn the key from the OFF position to the ON position.Ģ. Obtain a good scanner/programmer with suitable IDS softwareġ. To do a PATS Parameter Reset - follow these instructions

GEM Module - The Integrated Keyhead Transmitter (IKT) is your coded (PATS) ignition keys Please note :- This procedure does not erase the Integrated Keyhead Transmitter (IKT) identification codes (Transmitter Identification Codes (TICs) from the

To solve this problem, using a scanner with suitable IDS software & 2 coded (PATS) ingition keys, you do a PATS Parameter Reset for instrument cluster & ECU I was informed that when replacing the instrument panel or ECU or both, it is the immobilser which causes the engine not to start. The re-coding of the instrument cluster can be done yourself which a good scanner & IDS software ! On connects from 2006 to present, the immobiliser is part of the instrument cluster - Hence why they require re-coding when replaced. On connects from 2003-2006 the immobiliser is built into the PCM (engine ECU) Info regarding immobiliser (PATS) on the connects:D
