Diagnostic ProcedureBCS001HA
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis check. Refer to CVT-47, "
SELF-DIAGNOSTIC RESULT MODE" .
Is any malfunction of the
“U1000 CAN COMM CIRCUIT” indicated?
YES >> Check CAN communication line. Refer to CVT-53, "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK STOP LAMP SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
3. Read out ON/OFF switching action of the “BRAKE SW”.
OK or NG
OK >>INSPECTION END
NG >> GO TO 3.
3. CHECK STOP LAMP SWITCH
Check continuity between stop lamp switch harness connector termi-
nals 3 and 4. Refer to CVT-160, "
Wiring Diagram — CVT — NON-
DTC" .
Check stop lamp switch after adjusting brake pedal — refer to
BR-6, "
BRAKE PEDAL" .
OK or NG
OK >> Check the following. If NG, repair or replace damaged
parts.

Harness for short or open between battery and stop lamp switch.

Harness for short or open between stop lamp switch and unified meter and A/C amp.
NG >> Repair or replace the stop lamp switch.

“TRANSMISSION” with CONSULT-II.
3. Start vehicle and read out the value of “SEC PRESS”.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2. CHECK LINE PRESSURE
Perform line pressure test. Refer to CVT-33, "
LINE PRESSURE
TEST" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts. Refer to CVT-34,
"Judgement of Line Pressure Test" .
