Diagnostic procedure
STEP INSPECTION ACTION
1 VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED
• Has FREEZE FRAME PID DATA been
recorded?
Yes Go to next step.
No Record FREEZE FRAME PID DATA on repair order, then
go to next step.
2 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Bulletins and/or on-
line repair information availability.
• Is any related repair information available?
Yes Perform repair or diagnosis according to available repair
information.
• If vehicle is not repaired, go to next step.
No Go to next step.
3 INSPECT TERMINAL COMPONENT NO.2 (8-
PIN) CONNECTOR FOR POOR CONNECTION
• Turn ignition key to OFF.
• Disconnect terminal component No.2 (8-pin)
connector.
• Check for poor connection (damaged, pulled-
out terminals, corrosion, etc.).
• Are terminals okay?
Yes Go to next step.
No Repair or replace terminals, then go to Step 12.
4 INSPECT INTERMEDIATE SENSOR
RESISTANCE
• Measure resistance between terminal
component No.2 (8-pin) (transaxle case side).
• Is resistance within 513—627 ohms between
terminal component No.2 (8-pin) terminal C
and D (transaxle case side)?
Yes Go to next step.
No Go to Step 8
5 INSPECT TCM CONNECTOR FOR POOR
CONNECTION
• Disconnect TCM connector.
• Check for poor connection (damaged, pulled-
out terminals, corrosion, etc.).
• Are terminals okay?
Yes Go to next step.
No Repair terminals, then go to Step 12.
6 INSPECT TERMINAL COMPONENT NO.2 (8-
PIN) CIRCUIT FOR OPEN
• Check terminal component No.2 (8-pin)
terminals (harness-side) and TCM terminals
(harness-side).
— C and 1K
— D and 1X
• Is there continuity?
Yes Go to next step.
No Repair or replace harness, then go to Step 12.
7 INSPECT TERMINAL COMPONENT NO.2 (8-
PIN) CIRCUIT FOR SHORT TO GROUND
• Check terminal component No.2 (8-pin)
terminal (harness-side) and body ground.
— C and body ground
— D and body ground
• Is there any continuity?
Yes Repair or replace harness, then go to Step 12.
No Go to Step 12.
8 INSPECT COUPLER COMPONENT (8-PIN)
CONNECTOR FOR POOR CONNECTION
• Disassemble the control valve body cover.
• Disconnect coupler component (8-pin)
connector.
• Check for poor connection (damaged, pulled-
out terminals, corrosion, etc.).
• Are terminals okay?
Yes Go to next step.
No Repair terminals, then go to Step 12.
9 INSPECT INTERMEDIATE SENSOR
RESISTANCE
• Measure resistance between coupler
component (8-pin).
• Is resistance within 513—627 ohms between
coupler component (8-pin) terminal D and C
(part side)?
Yes Repair or replace coupler component, then go to Step 12.
No Go to next step.
