DTC U1000 CAN COMMUNICATION LINEPFP:31940
DescriptionECS008CZ
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 error detection ability. Many elec-
tronic 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 connected 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 LogicECS008D0
Possible CauseECS00CUO
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureECS008D1
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 “A/T” with CONSULT-II.
3. Wait at least 6 seconds or start engine and wait for at least 6
seconds.
4. If DTC is detected, go to AT- 9 9 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”
WITHOUT CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Wait at least 6 seconds or start engine and wait at least 6 seconds.
3. Perform self-diagnosis.
Refer to AT- 5 2 , "
Diagnostic Procedure Without CONSULT-II" .
4. If DTC is detected, go to AT- 9 9 , "
Diagnostic Procedure" .

DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCHPFP:32006
DescriptionECS004QW

The PNP switch assembly includes a transmission range switch.

The transmission range switch detects the selector lever posi-
tion and sends a signal to the TCM.

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 5 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. CHECK PNP SWITCH CIRCUIT (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to ON. (Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out P/N, R, D, 2 and 1 position switches moving selector
lever to each position.
Check that the signal of the selector lever position is indicated
properly.
OK or NG
OK >> GO TO 7.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING ITEM
Check continuity between PNP switch harness connector terminals.
OK or NG
OK >> GO TO 5.
NG >> GO TO 4.
4. CHECK MANUAL CONTROL CABLE ADJUSTMENT
Check PNP switch again with manual control cable disconnected from manual shaft of A/T assembly. Refer to
test group 1.
OK or NG
OK >> Adjust manual control cable. Refer to AT- 4 0 9 , "Control Cable Adjustment" .
