Diagnostic procedure
STEP
1 VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED
• Has FREEZE FRAME PID DATA been
recorded?
2 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Bulletins and/or on-
line repair information availability.
• Is any related repair information available?
3 INSPECT TERMINAL COMPONENT NO.1 (12-
PIN) FOR POOR CONNECTION
• Turn ignition key to OFF.
• Disconnect terminal componentNo.1 (12-pin).
• Check for poor connection (damaged, pulled-
out, terminals, corrosion, etc.).
• Are terminals okay?
4 INSPECT RESISTANCE
• Check resistance between terminal component
No.1 (12-pin) terminal H (transaxle case side)
and body ground.
• Is resistance within 12—13.2 ohms?
(See K2–88 SOLENOID VALVE
5 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?
6 INSPECT RESISTANCE
• Check resistance between coupler component
(10-pin) terminal C (part side) and body
ground.
• Is resistance within 12—13.2 ohms?
(See K2–88 SOLENOID VALVE
7 INSPECT TCC SOLENOID VALVE
CONNECTOR FOR POOR CONNECTION
• Disconnect TCC solenoid valve connector.
• Check for poor connection (damaged, pulled-
out, terminals, corrosion, etc.).
• Is terminal okay?
8 INSPECT RESISTANCE
• Check resistance between TCC solenoid valve
connector (part side) terminal A and body
ground.
• Is resistance within 12—13.2 ohms?
(See K2–88 SOLENOID VALVE
9 INSPECT TCM CONNECTOR FOR POOR
CONNECTION
• Disconnect TCM connector.
• Check for poor connection (damaged, pulled-
out, terminals, corrosion, etc.).
• Are terminals okay?
10 INSPECT TERMINAL COMPONENT NO.1 (12-
PIN) CIRCUIT FOR OPEN CIRCUIT
• Check continuity between TCM terminal 2S
(harness-side) and terminal component No.1
(12-pin) terminal H (harness-side).
• Is there continuity between terminals?
