DTC P1815 MANUAL MODE SWITCH
Revision: 2005 July 2005 FX
DTC P1815 MANUAL MODE SWITCHPFP:34901
DescriptionACS002QA
Manual mode switch is installed in A/T device. It sends manual mode switch, shift up and shift down switch
signals to TCM.
TCM sends the switch signals to unified meter and A/C amp. By CAN communication line. Then manual mode
switch position is indicated on the A/T indicator. For inspection, refer to AT- 1 8 9 , "
A/T INDICATOR CIRCUIT" .
CONSULT-II Reference Value in Data Monitor ModeACS002QB
On Board Diagnosis LogicACS002QC

This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “P1815 MANU MODE SW/CIR” with CONSULT-II is detected when TCM moni-
tors Manual mode, Non manual mode, Up or Down switch signal, and detects as irregular when impossi-
ble input pattern occurs 1 second or more.
Possible CauseACS002QD

Harness or connectors
(These switches circuit is open or shorted.)

Manual mode select switch (Into control device)

Manual mode position select switch (Into control device)
DTC Confirmation ProcedureACS002QE
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing 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 “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” 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 AT- 1 7 3 , "
Diagnostic Procedure" .

3. Read out ON/OFF switching action of “MANU MODE SW”, “NON M-MODE SW”, “UP SW LEVER”, “DOWN SW LEVER”.
Without CONSULT-II
Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the
position mutually coincide when the selector lever is shifted to the “+ (up)” or “- (down)” side (1st ⇔ 5th gear).
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING ITEM
Check the following items.

Manual mode switch. Refer to AT- 1 7 4 , "Component Inspection" .
