Overall Function Check
EBS00MMB
Use this procedure to check the overall function of the park/neutral position (PNP) switch circuit. During this
check, a 1st trip DTC might not be confirmed.
WITH GST
1.
Turn ignition switch “ON”.
2.
Check voltage between ECM terminal 80 (PNP switch signal)
and ground under the following conditions.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure
EBS00MMD
1.
INSPECTION START
Do you have CONSULT-II?
Yes or No
Yes
>> GO TO 2.
No
>> GO TO 3.
2.
CHECK PNP SWITCH SIGNAL
With CONSULT-II
1.
Turn ignition switch “ON”.
2.
Select “A/T”, then “DATA MONITOR” mode with CONSULT-II.
3.
Select “P/N POSI SW” signal and check its indication under the
following conditions.
OK or NG
OK
>> GO TO 5.
NG
>> GO TO 4.
3.
CHECK PNP SWITCH
Without CONSULT-II
Confirm that the PNP switch signal is sent to TCM correctly.
Refer to
AT-105, "DTC P0705 PARK/NEUTRAL POSITION SWITCH"
OK or NG
OK
>> GO TO 5.
NG
>> GO TO 4.
4.
CHECK PNP SWITCH CIRCUIT
Check the PNP switch circuit.
Refer to
AT-105, "DTC P0705 PARK/NEUTRAL POSITION SWITCH"

5.
CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT-I
1.
Turn ignition switch “OFF”.
2.
Disconnect TCM harness connector.
3.
Disconnect fuse block (J/B) No. 1 harness connector.
4.
Check harness continuity between TCM terminal 48 and fuse
block (J/B) No.1 terminal 17D.
Refer to Wiring Diagram.
5.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 7.
NG
>> GO TO 6.
6.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors F105, M135
●
Harness for open or short between TCM and fuse block (J/B) No. 1
>> Repair open circuit or short to ground or short to power in harness or connectors.
7.
CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT-II
1.
Check harness continuity between fuse block (J/B) No. 1 terminal 1E and ground.
Refer to Wiring Diagram.
2.
Also check harness for short to power.
OK or NG
OK
>> GO TO 8.
NG
>> Repair open circuit or short to power in harness or connectors.
8.
CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT-III
1.
Disconnect ECM harness connector.
2.
Check harness continuity between ECM terminal 80 and fuse block (J/B) No. 1 terminal 19D.
Refer to Wiring Diagram.
3.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 10.
NG
>> GO TO 9.
9.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness connectors F105, M135
●
Joint connector-17
●
Harness for open or short between ECM and fuse block (J/B) No. 1
>> Repair open circuit or short to ground or short to power in harness or connectors.
