1.DEF: CONVERTER LOCK-UP CONTROL
NOTESOrder of priority in the event of more than one fault:
If there is a combination of the following faults:
–DF097 "Converter lock-up",
–DF086 "Sequence solenoid valve circuit "EVS2*""
–DF306 "Lock-up/brake 1 solenoid valve circuit",
deal first with faults DF086 "Sequence solenoid valve "EVS2*"" and DF306 "Lock-
up/brake 1 solenoid valve circuit".
Conditions for applying fault finding procedures to stored faults:
The fault is declared present after:
If in lock-up:
Lever in Manual position,
and difference in *slippage speed ≥ 40 + Vehicle speed / 2 for a certain time,
and EVS2* solenoid valve control status > 95 %.
In the event of slippage:
Lever in Manual position,
and difference in slippage speed ≥ 40 + slippage speed setpoint for a certain time,
and EVS2* solenoid valve control status > 95 %.
*slippage = engine speed - turbine speed
Effect on system:
Increase in oil temperature.
–In the event of engagement fault, lock-up inhibited.
–In the event of slippage fault, lock-up slippage inhibited.
Customer complaint:
Warning light on.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
