DTC P0798: Pressure Control Solenoid "C" Electrical (Shift Solenoid Valve SL3) [12/2012 - ]: Procedure
WARNING: This page is about a different variant/trim than selected.
- CHECK HARNESS AND CONNECTOR (SHIFT SOLENOID VALVE SL3 CIRCUIT)
- Disconnect the ECM connector.
*a Front view of wire harness connector
(to ECM) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition B77-11 (SL3+) - B77-10 (SL3-) 20°C (68°F) 5.0 to 5.6 Ω B77-11 (SL3+) - Body ground and other terminals Always 10 kΩ or higher B77-10 (SL3-) - Body ground and other terminals Always 10 kΩ or higher
Result:
OK
REPLACE ECM: REMOVAL [12/2012 - ]
Result:
NG
See step 2
- Disconnect the ECM connector.
- CHECK HARNESS AND CONNECTOR (WIRING HARNESS CONNECTOR - ECM)
- Disconnect the B78 wiring harness connector.
- Disconnect the B77 ECM connectors.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition B78-19 (SL3+) - B77-11 (SL3+) Always Below 1 Ω B78-18 (SL3-) - B77-10 (SL3-) Always Below 1 Ω B78-19 (SL3+) or B77-11 (SL3+) - Body ground and other terminals Always 10 kΩ or higher B78-18 (SL3-) or B77-10 (SL3-) - Body ground and other terminals Always 10 kΩ or higher
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 3
- INSPECT TRANSMISSION WIRE (SHIFT SOLENOID VALVE SL3)
- Remove the wiring harness connector.
*a Component without harness connected
(Transmission Wire) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition A-16 (SL3+) - A-15 (SL3-) 20°C (68°F) 5.0 to 5.6 Ω A-16 (SL3+) - Body ground Always 10 kΩ or higher A-15 (SL3-) - Body ground Always 10 kΩ or higher
Result:
OK
REPLACE WIRING HARNESS CONNECTOR: REMOVAL [12/2012 - 08/2017] , REMOVAL [08/2017 - ]
Result:
NG
See step 4
- Remove the wiring harness connector.
- INSPECT SHIFT SOLENOID VALVE SL3
- Remove shift solenoid valve SL3.
*1 Shift Solenoid Valve SL3 - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 5.0 to 5.6 Ω - Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.
OK
Measurement Condition Specified Condition - Battery positive (+) with a 21 W bulb → Terminal 1
- Battery negative (-) → Terminal 2
Valve moves and makes an operating noise
Result:
OK
REPLACE TRANSMISSION WIRE: REMOVAL [12/2012 - ]
Result:
NG
REPLACE SHIFT SOLENOID VALVE SL3: DISASSEMBLY [12/2012 - ]
- Remove shift solenoid valve SL3.
