 WTEC III ELECTRONIC CONTROLS TROUBLESHOOTING MANUAL
DIAGNOSTIC CODES
SOLenoid OFF (SOL OFF) Response
-- All solenoids are commanded off (turning solenoids "A" and "B" off electrically causes them to be
on hydraulically).
Return to Previous Range (RPR) Response
-- When the speed sensor ratio or C3 pressure switch tests associated with a shift are not successful,
the ECU commands the same range as commanded before the shift.
Neutral No Clutches (NNC) Response
-- When certain speed sensor ratio or C3 pressure switch tests are not successful, the ECU commands
a neutral condition with no clutches applied.
"Cateye" -- The forward slash segments and the middle horizontal segments (-\-) may be on under the
following conditions:
-- RSI link fault is active (code 23 12 or 23 14)
-- When two COP timeouts occur within two seconds of each other (reference code 69 33)
-- Shift selector display line fault is active (23 16)
All Segments Displayed -- All display segments will be illuminated if a severity 1 diagnostic code is
present during initialization, or if an electrical code for solenoids A, B, C, D, E, or G is logged before
initialization completes.
