TCM terminal data are reference values, measured between each terminal and ground.
Diagnostic ProcedureBCS001H4
1. CHECK STARTER RELAY
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “TRANSMISSION” with CONSULT-II and check monitor
“STRTR RLY OUT”, “STRTR RLY MON”(PNP relay) ON/OFF.
Without CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between the TCM connector terminal and
ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. DETECT MALFUNCTIONING ITEM
Check the following:

Starter relay. Refer to PG-77, "STANDARDIZED RELAY" .

Open or short-circuit in the harness between TCM and the stater relay. Refer to CVT-57, "Wiring Diagram
— CVT — STSIG" .

Ground circuit for the starter relay. Refer to SC-15, "Wiring Diagram — START —" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.
3. CHECK DTC
Perform “DTC Confirmation Procedure”. Refer to CVT-56, "
DTC Confirmation Procedure" .
OK or NG
OK >>INSPECTION END
NG >> GO TO 4.

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.

TCM terminal data are reference values, measured between each terminal and ground.
Diagnostic ProcedureBCS001I4
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
3. Start vehicle and read out the value of “VSP SENSOR”.
OK or NG
OK >> GO TO 8.
NG >> GO TO 2.
2. CHECK SECONDARY SPEED SENSOR
With CONSULT-II
1. Start engine.
2. Check power supply to output speed sensor (secondary speed sensor) by voltage between TCM connec-
tor terminals 10, 19 and 42. Refer to CVT-31, "
Circuit Diagram" .
3. If OK, check the pulse when vehicle cruises.
OK or NG
OK >> GO TO 8.
NG >> GO TO 3.
