STEP
3 INSPECT RESISTANCE
• Check resistance between terminal component
No.1 (12-pin) terminal D (transaxle case side)
and body ground.
• Is resistance within 2.6—3.2 ohms?
(See K2–88 SOLENOID VALVE
4 INSPECT COUPLER COMPONENT (10-PIN)
FOR POOR CONNECTION
• Disconnect coupler component (10-pin)
connector.
• Check for poor connection (damaged, pulled-
out, terminals, corrosion, etc.).
• Is terminal okay?
5 INSPECT RESISTANCE
• Check resistance between coupler component
(10-pin) terminal L (part side) and body ground.
• Is resistance within 2.6—3.2 ohms?
(See K2–88 SOLENOID VALVE
6 INSPECT PRESSURE CONTROL SOLENOID
CONNECTOR FOR POOR CONNECTION
• Disconnect pressure control solenoid
connector.
• Check for poor connection (damaged, pulled-
out, terminals, corrosion, etc.).
• Is terminal okay?
7 INSPECT RESISTANCE
• Check resistance between pressure control
solenoid connector (part side) terminal A and
body ground.
• Is resistance within 2.6—3.2 ohms?
(See K2–88 SOLENOID VALVE
8 INSPECT TCM CONNECTOR FOR POOR
CONNECTION
• Disconnect TCM connector.
• Check for poor connection (damaged, pulled-
out, terminals, corrosion, etc.).
• Are terminals okay?
9 INSPECT TERMINAL COMPONENT NO.1 (12-
PIN) CIRCUIT FOR OPEN CIRCUIT
• Check continuity between TCM terminal 2Y
(harness-side) and terminal component No.1
(12-pin) terminal D (harness-side).
• Is there continuity between terminals?
10 INSPECT TERMINAL COMPONENT NO.1 (12-
PIN) CIRCUIT FOR SHORT TO POWER
• Turn ignition key to ON (engine OFF).
• Check voltage at terminal component No.1 (12-
pin) terminal D (harness-side).
• Is voltage 0 V?
11 INSPECT TCM CIRCUIT FOR SHORT TO
GROUND
• Turn ignition key to OFF.
• Check continuity between TCM terminal 2Y
(harness-side) and body ground.
• Is there any continuity?
12 VERIFY TROUBLESHOOTING OF DTC P0748
COMPLETED
• Make sure to reconnect all disconnected
connectors.
• Clear DTC from memory using WDS or
equivalent.
• Drive vehicle in D range and make sure that
gears shift smoothly from 1GR to 5GR.
• Is same DTC present?
