TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionBCS0011O
Torque converter clutch solenoid valve is activated, with the gear in D4 , D3 and 33 , by TCM in response to
signals sent from vehicle speed and the ECM (throttle opening). Lock-up piston operation will then be con-
trolled.
Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
CONSULT-II Reference ValueBCS0011P
On Board Diagnosis LogicBCS0011Q
Diagnostic trouble code “T/C CLUTCH SOL/V” with CONSULT-II or 7th judgement flicker without CONSULT-II

DTC Confirmation ProcedureBCS0011S
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
After the repair, perform the following procedure to confirm that the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II and
wait at least 1 second.
3. Start engine and maintain the following condition for at least 5
consecutive seconds.

LINE PRESSURE SOLENOID VALVEPFP:31940
DescriptionBCS0012I
Line pressure solenoid valve regulates oil pump discharge pressure to suit the driving condition in response to
a signal sent from TCM.
The line pressure duty cycle value is not consistent when the closed throttle position switch is ON. To
confirm the line pressure duty cycle at low-pressure, accelerator (throttle) should be open until the
closed throttle position switch is “OFF”.

A/T SHIFT LOCK SYSTEM

A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionBCS0014Z

The electrical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, selector lever cannot be shifted from “P” to any other position unless
brake pedal is depressed.
With the key removed, selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless selector lever is placed in “P”.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside key cylinder, respectively.
Shift Lock System Electrical Parts LocationBCS00150
NOTE:
This emergency lever insures that when battery is off ignition key cannot be removed.Inthe situation like this,
by operating this lever, ignition key can be removed.
