M12301000426USA0000010000

DESCRIPTIONS OF MONITOR METHODS

｠

With the mode other than SPORT MODE and with
the  accelerator  angle  is  smaller  than  6/8,  the
correlation  between  the  lock-up  and  low-reverse
brake linear solenoid valve control current and the
low-reverse  brake  pressure  switch  ON/OFF  is
abnormal.

TROUBLESHOOTING HINTS (THE MOST LIKELY
CAUSES FOR THIS CODE TO BE SET ARE:)

｠

Transaxle assembly powertrain parts failure

｠

Malfunction of the valve assembly (Malfunction of
hydraulic valve and hydraulic switch)

｠

Malfunction of the TCM

｠

Malfunction  of  the  lock-up  and  low-reverse  brake
linear solenoid valve (valve assembly)

｠

Malfunction  of  the  low-reverse  brake  pressure
switch (valve assembly)

｠

Malfunction of the low clutch pressure switch (valve
assembly)

｠

Malfunction of the low clutch linear solenoid valve
(valve assembly)

｠

Malfunction of the low-reverse brake shift solenoid
valve (valve assembly)

｠

Malfunction of the low clutch, low-reverse brake

 

DIAGNOSIS

STEP 1. Check the DTC.
Check  that  P0841  (Low-clutch  pressure  switch)  and  P0988
(Low-reverse brake pressure switch) are set.

Q:Is the DTC set?

YES:

 Check and repair the relevant DTC system.

NO:

 Go to Step 2.

STEP 2. Check the DTC.
