connectors.
2) Check for proper connection to TCM at terminal
E203-11 and E203-8.
3) If OK, measure voltage between terminal
E203-8 of disconnected harness side TCM
connectors and ground.
Is it about 0 V?
3 Check pressure control solenoid circuit for short.
Measure resistance between terminal E203-11 or
disconnected harness side TCM connector and
ground.
Is it infinity?
4 Check pressure control solenoid circuit for short.
Measure resistance between terminal E203-8 and
E203-11 of disconnected harness side TCM
