2010 RXTiS - (I've searched and read most post on this issue but haven't found exactly what I'm looking for yet....?)
Problem - Getting codes P1661, U16A4, U16A5, U0129 and IBR not working in water but works sometimes on lift.
1. Ski in really good condition, only 150 hours ridden mostly slow by senior adult and only had driveshaft failure issue to date.....which I replaced with new style and all was good.
2. Used ski about a month ago with no issues.
3. Found a bird nest up in the pump tunnel and cleaned out...went to Override IBR to help cleaning but found battery dead...only 5.5 vdc.
4. Replaced battery with new tested battery.
5. Now IBR is not working correctly.
Symptoms -
1. IBR and Engine lights in dash, no R/N/F, no trim indication.
2. IBR will not Override or work.
3. Trim will not work.
4. iS works but when manually motored down all the way the actuator keeps running till motored back up a bit.
5. Engine starts and runs fine.
Troubleshooting -
1. Checked all fuses and connections around the battery, since I had to pull on those wires to get battery replaced.
2. Checked all bird nest debris had been removed for the reverse and trim linkages.
3. Checked the main wire connection under the dash.
4. Moving the wiring near battery will sometime allow the IBR Override to work and everything starts functioning normal, even when engine started on the boat lift, but when I put it in the water it malfunctions again.
I believe I probably pulled a wire too hard when replacing the battery, but which one?
Any help would be appreciated.
Question - Will the codes clear themselves once the problem is corrected....maybe after several start cycles with no problem?
P1661 - ECM iBR MALFUNCTION
U16A4 - ECU TIMED OUT WAITING FOR iBR ON CAN BUS
U16A5 - ECU TIMED OUT WAITING FOR iBR ON CAN BUS
U0129 - CAN COMMUNICATIONS BETWEEN ERROR AND WCM iBR
