INSPECTION PROCEDURE
- HINT:
- According to the DATA LIST displayed by the intelligent tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor time.
- NOTICE:
- In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
Turn the ignition switch off.
Connect the intelligent tester together to the DLC3.
Turn the ignition switch on (IG).
Turn on the tester.
Select the item "Powertrain / ECT / Data List".
According to the display on the tester, read the "DATA LIST".
Item
| Measurement Item / Range (Display)
| Normal Condition
| Diagnostic Note
|
Neutral Position SW Signal
| PNP SW Status / ON or OFF
| Shift lever position is; P and N: ON Except P or N: OFF
| When the shift lever position displayed on the intelligent tester differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect.
|
Shift SW status (R Range)
| PNP SW Status / ON or OFF
| Shift lever position is; R: ON Except R: OFF
| When the shift lever position displayed on the intelligent tester differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect.
|
Shift SW status (D Range)
| PNP SW Status / ON or OFF
| Shift lever position is; D and S: ON Except D or S: OFF
| When the shift lever position displayed on the intelligent tester differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect.
|
1.CHECK HARNESS AND CONNECTOR (D, R POSITION CIRCUIT) |
Disconnect the park / neutral position switch connector.
Turn the ignition switch on (IG).
Measure voltage according to the value(s) in the table below.
- Standard voltage:
Tester Connection
| Specified Condition
|
RB (C1-1) - Body ground
| 10 to 14 V
|
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
2.CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ST RELAY) |
Disconnect the park/neutral position switch connector.
Remove the ST relay from the engine room relay block.
Measure the resistance between the terminals.
- Standard resistance:
Tester Connection
| Specified Condition
|
L (C1-9) - ST relay terminal 1
| Below 1 Ω
|
Install the ST relay.
Reconnect the park/neutral position switch connector.
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
Remove the ST relay from the engine room relay block.
Measure the resistance between the terminals.
- Standard resistance:
Tester Connection
| Specified Condition
|
3 - 5
| 10 kΩ or higher
|
3 - 5
| Below 1 Ω Apply battery voltage between terminals 1 and 2
|
4.CHECK HARNESS AND CONNECTOR (ST RELAY - BODY GROUND) |
Remove the ST relay from the engine room relay block.
Measure the resistance between the terminals
- Standard resistance:
Tester Connection
| Specified Condition
|
ST relay terminal 2 - Body ground
| Below 1 Ω
|
Install the ST relay.
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
5.INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY |
Measure resistance according to the value(s) in the table below when the shift lever is moved to each position.
- Standard resistance:
Shift Position
| Tester Connection
| Specified Condition
|
P
| 1 - 3 and 4 - 9
| Below 1 Ω
|
Except P
| 10 kΩ or higher
|
R
| 1 - 2
| Below 1 Ω
|
Except R
| 10 kΩ or higher
|
N
| 1 - 8 and 4 - 9
| Below 1 Ω
|
Except N
| 10 kΩ or higher
|
D, S, ''+'' and ''-''
| 1 - 7
| Below 1 Ω
|
Except D, S, ''+'' and ''-''
| 10 kΩ or higher
|
6.CHECK HARNESS AND CONNECTOR |
Connect the park/neutral position switch connector.
Disconnect the TCM connectors.
Turn the ignition switch to the ON position, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.
- Standard voltage:
Shift Position
| Tester Connection
| Specified Condition
|
R
| R (C56-15) - Body ground
| 10 to 14 V *
|
Except R
| Below 1 V
|
D
| D (C56-16) - Body ground
| 10 to 14 V
|
Except D
| Below 1 V
|
- HINT:
- *: The voltage will drop slightly due to lighting up of the back up light.
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
7.CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ECM) |
Disconnect the ECM connectors.
Turn the ignition switch off.
Measure resistance according to the value(s) in the table below.
- Standard resistance (Check for open):
Tester Connection
| Specified Condition
|
B (C1-4) - NSW (C56-11)
| Below 1 Ω
|
- Standard resistance (Check for short):
Tester Connection
| Specified Condition
|
B (C1-4) or NSW (C56-11) - Body ground
| 10 kΩ or higher
|
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
