Smart Tire Error Codes & Troubleshooting

Question came up about error codes, so I pulled the owner's manual & under troubleshooting it lists 4 possible error codes:
Code...ItemFailing...Fault........................ ........Action
E1...Sensor(s)/Receiver...Not transmitting, RF section malfunction.....If no transmission rec'd w/in 5 min. of driving refer to "Troubleshooting" before contacting dealer
E2...Receiver &/or Display...EPROM fault...Refer to "Troubleshooting" before contacting dealer
E3...Receiver &/or Display...Oscillator fault...Refer to "Troubleshooting" before contacting dealer
E4...Receiver &/or Display...Internal bus fault...Refer to "Troubleshooting" before contacting dealer

E1- This error may occur in certain vehicles where the receiver unit is powered even when the ignition is turned off. Cases include vehicles where the cigarette lighter outlet is powered w/out the vehicle running. Other possible causes may be broken tire sensors or malfunctioning Receiver unit. Mismatches in tire sensor ID may also cause this problem.
E2- Indicates a problem with the data in Receiver &/or Display units. Causes include- corrupted custom profile, corrupted factory profile. The following may help to identify the problem better: Power the unit on & off; if error clears-> Operating w/incorrect setting, contact dealer. If error persists-> Receiver (or Display) may have to be replaced.
E3 & E4- These errors will usually indicate internal fault. Try powering unit off & on. If errors persist the unit may have to be replaced.

the manual is a bizarrely small size. I will try to get it scanned this week & added to the ACA Technical Library.

Here is a link to a thread w/leads on service parts. The Bob Dickman tire link is still live.
Sensors on my rig are 101-1-5-xxxxxxx serial numbered; guessing the initial numbers are a model#.
