SHIFT SOLENOID VALVE A

SHIFT SOLENOID VALVE APFP:31940
DescriptionBCS00110
Shift solenoid valves A and B are turned ON or OFF by TCM in response to signals sent from PNP switch,
vehicle speed and ECM (throttle opening). Gears will then be shifted to the optimum position.

On Board Diagnosis LogicBCS00112
Diagnostic trouble code “SHIFT SOLENOID/V A” with CONSULT-II or 4th judgement flicker without CON-
SULT-II is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Possible CauseBCS00113

Harness or connector
(Solenoid circuit is open or shorted.)

CAN COMMUNICATION LINEPFP:31940
DescriptionBCS0012P
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicBCS0012Q
Diagnostic trouble code “CAN COMM CIRCUIT” with CONSULT-II or 12th judgement flicker without CON-
SULT-II is detected when TCM cannot communicate to other control units.
Possible CauseBCS0012R
Harness or connector
(CAN communication line is open or shorted.)

TCM Self-diagnosis Does Not ActivateBCS0014V
SYMPTOM:
A/T CHECK indicator lamp does not come on in TCM self-diagnostic procedure even if the lamp circuit
is good.
DESCRIPTION

PNP switch
PNP switch includes a transmission range switch. The transmission range switch detects the selector
lever position and sends a signal to the TCM.

3rd position switch
3rd position switch detects the 3rd position and sends a signal via CAN communication to the TCM.

Closed throttle position signal and wide-open throttle position signal.
ECM judges throttle opening based on a signal from accelerator pedal position (APP) sensor, and sends
the signal via CAN communication to TCM.

Stop lamp switch
Stop lamp switch detects the switch position (ON or OFF) and sends a signal via CAN communication to
the TCM.
DIAGNOSTIC PROCEDURE
NOTE:
The diagnostic procedure includes inspection for the park/neutral position (PNP) stitch, 3rd position switch,
stop lamp switch, closed throttle position signal and wide open throttle position signal circuit. Refer to AT- 1 6 1 ,
"PNP, 3RD POSITION SWITCH AND CLOSED THROTTLE, WIDE OPEN THROTTLE POSITION SIGNAL"
and AT- 1 6 7 , "BRAKE SIGNAL CIRCUIT" .
