TROUBLESHOOTING [GF4A-EL]
DTC P0760 Shift solenoid C circu it failure
DESCRIPTION
• Damaged wiring or connectors between shift solenoid C and powertrain control module
• Short or open circuit in shift solenoid C
• Short or open circuit in powertrain control module Internal transistor
POSSIBLE
CAUSE
• Damaged wiring or connectors between shift solenoid C and powertrain control module
• Short or open circuit in shift solenoid C
• Short or open circuit in powertrain control module internal transistor
STEP
INSPECTION ACTION
1 Are powertrain control module and shift solenoid
C connections at connector and connector pins
okay?
Yes Go to next step
No Repair or replace connector(s), then go to step 7
2
Check NGS tester display
• Connect NGS tester to data link connector
• Are shift solenoid C operation and NGS tester
display correct?
ty 01—40B POWERTRAIN CONTROL
MODULE (PCM) INSPECTION [KL]
Yes Go to step 7
No Go to next step
3
Check for continuity between terminals of shift
solenoid C and powertrain control module
• Disconnect negative battery cable
• Disconnect solenoid connector and powertrain
control module connector
• Is there continuity between terminals?
Yes Go to next step
No Repair or replace connectors and wiring, then go to step 7
4 Check for a short circuit between terminals of shift
solenoid C and powertrain control module.
• Disconnect solenoid and powertrain control
module connectors
• Connect ohmmeter between GND and shift
solenoid C connector terminal
• Is continuity present?
Yes Repair short circuit, then go to step 7
No Go to next step
5
Measure resistance at shift solenoid C terminal
•
Disconnect negative battery cable
•
Disconnect solenoid connector
•
Is resistance correct?

After diagnostic trouble code has been cleared,
recheck if diagnostic trouble code is shown
c r 0 1 -0 1 B ENGINE ON-BOARD DIAGNOSIS
[KL]
Yes
Return to step 2
No
Problem is a temporary poor connection of wiring or
connectors, and should be investigated further, then go to
next step
7 Erase diagnostic trouble code from memory. Can
code be output after performing “After Repair
Procedure”?
Yes Go to appropriate inspection procedure
No Finished
