DTC P0826 MANUAL MODE SWITCH CIRCUITPFP:34901
DescriptionBCS001JN
Manual mode switch is installed in CVT control device. The manual mode switch sends shift up and shift down
switch signals to TCM.
TCM sends the switch signals to unified meter and A/C amp via CAN communication line. Then manual mode
switch position is indicated on the shift position indicator. For inspection, refer to CVT-159, "
Diagnostic Proce-
dure" .
CONSULT-II Reference ValueBCS001JO
On Board Diagnosis LogicBCS001JP
Diagnostic trouble code “P0826 MANUAL MODE SWITCH” with CONSULT-II is detected when TCM monitors
Manual mode, Non manual mode, Up or Down switch signal, and then detects irregular with impossible input
pattern for 1 second or more.
Possible CauseBCS001JQ

Harness or connectors
(These switches circuit is open or shorted.)
(TCM, and unified meter and A/C amp circuit are open or shorted.)
(CAN communication line is open or shorted.)

Manual mode select switch (Built into CVT control device)

Manual mode position select switch (Built into CVT control device)
DTC Confirmation ProcedureBCS001JR
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine.
4. Move selector lever to “M” position.
5. Drive vehicle for at least 2 consecutive seconds.
6. If DTC is detected, go to CVT-115, "
Diagnostic Procedure" .

Is any malfunction detected by self-diagnosis?
YES >> Check the malfunctioning system.
NO >> GO TO 6.
6. CHECK MANUAL MODE SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect CVT device connector and unified meter and A/C amp connector.
3. Check continuity between CVT device harness connector termi-
nals and unified meter and A/C amp harness connector termi-
nals.
4. Check continuity between CVT device harness connector termi-
nal and ground.
5. If OK, check harness for short to ground and short to power.
6. Reinstall any part removed.
OK or NG

2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >>INSPECTION END
NG >> Repair or replace damaged parts.

This self-diagnosis has the one trip detection logic. When malfunction A is detected, DTC is not
stored in ECM memory. And in that case, 1st trip DTC and 1st trip freeze frame data are displayed.
1st trip DTC is erased when ignition switch OFF. And even when malfunction A is detected in two
consecutive trips, DTC is not stored in ECM memory.
