TSB 14-0020 - DTC P1A18, P1A19, P0AEE, P0BCD When Using Engine Block Heater

[larryh]

I am using the scanner and software described in: http://fordfusionhybridforum.com/topic/8074-dtc-p1a18-p1a19-p0aee-p0bcd-when-using-engine-block-heater-under-investigation/?p=73590

 

The formulas for the PIDs for my software are posted here: (The site is not letting me post the link. See the following post).

They are not quite right. Some of the values are 2's complement numbers and should be written as (signed(a)*256) + b rather than (a*256) + b.

 

The corresponding Scan Gauge codes are here: http://fordcmaxenergiforum.com/topic/1293-scangauge-x-gauges-programming-c-max-ffh/?p=8210

This site is not allowing me to post the web address with the formulas for the PIDs for my software above. I'll try it here. No matter what I do, it keeps deleting the link.

 

Let's see if this works:

The XGauge codes in that thread don't work for monitoring temps of MG1 or MG2. When I asked Ashley about XGauge codes, the official response was that Ford does not support ScanGauge use and won't share that data.

 

Where do you get the coding needed for your torque app?

Well those PIDs work for me to provide the motor and generator inverter temperatures. They are providing reasonable values at least. The formulas from my second post above are as follows:

 

ModeAndPID Name Min Max Unit Formula Header

224801 Hv Battery State-of-Charge 0 300 % (((A*256)+B)*(1/5))/100 0

22480D Hv Battery Voltage 0 300 Volts (((A*256)+B))/100 0

224800 Hv Battery Temp 0 300 F (A*18-580)/10 0

224815 Maximum Discharge Power Limit 0 300 kW (A*25)/10 0

224816 Maximum Charge Power Limit 0 300 kW (A*25)/10 0

224841 Average Battery Module Voltage 0 300 Volts (((A*256)+B)*(1/10))/10 0

22DD04 Inside Car Temp 0 300 F (A*18-400)/10 0

224810 Battery Age 0 300 months (((A*256)+B)*(1/20))/10 0

221E1C Transmission Temp 0 300 F (((A*256)+B)*(9/8)+320)/10 0

22480B Hv Current 0 300 amps (((A*256)+B)*(1/5))/10 0

224832 Motor Electronics Coolant Temp 0 300 F (A*18+320)/10 0

22F41F Engine run time 0 300 minutes (((A*256)+B)*(25/16))/10 0

22481E Generator Inverter Temp 0 300 F (((A*256)+B)*18+320)/10 0

224824 Motor Inverter Temp 0 300 F (((A*256)+B)*18+320)/10 0

As I mentioned previously, some of them should be (signed(a)*256) + b. The ranges are also incorrect.

I just recorded the sensor data for a bunch of PIDs for my 60 mile commute home today. I now have to figure out how to get them out of BlueStacks so that I can read them.

Using the ScanGauge doesn't read anything when the rents aluminate from using the block heater. I show 2 codes in ET Mode: C15900 & C46B86

Scan Gauge doesn't show any DTCs? When the Service Engine Soon light is on, I see the three codes that I indicated in the earlier post in this thread. Now, I usually turn the car on before plugging in the EBT so that the light does not come on--the car has to be off for three hours before the light will come on. I don't see any DTCs in ET mode. I attempted to ask FordService about the DTCs I observed with the scanner, but they refused to discuss DTCs read by the scanner.

I don't understand what you posted regarding ET Mode. I don't see any DTCs in ET mode.

The SGII will show DTCs when the CEL is on. In the hybrid, the yellow wrench comes on for the EBH issue, not the CEL. The codes shown in ET Mode are not read by the SGII as they are not standard DTCs.

 

I typed that last post using voice text on my iPhone and I didn't pay close enough attention to making sure that it understood me correctly. I fixed my post now.

So ET Mode shows all DTCs except OBD II DTCs? You need a scanner to read the OBD II DTCs?

I'm not sure. Check out the thread on ET Mode...

Larryh reports that there is now a TSB to fix this. TSB 14-0020. I cannot find the PDF of this TSB online.

I tried the EBH after applying TSB 14-0020 twice now. The SES light did not come on either time. For the second trial, the outside temperature was 70 F. The coolant temperature reach 149 F. The inverter temperatures for the generator and motor were 87.8 F and 91.4F. The temperature differences between the inverter temperatures and the coolant temperature was more than 30 C, which was the threshold for turning on the Service Engine Soon light. The temperature thresholds were also exceeded for the first trial. The real trial will be this coming winter.
