Check the following connectors:
Check trouble symptom.
Check the harness wire between the
module connector.
There is probably a problem in
system. Carry out automatic transaxle troubleshooting.
(Refer to GROUP Troubleshooting)
Replace the ECM.
Code No. PG Assy Malfunction
[Comment]
Background
The transaxle control module monitors the pulse signals of the pulse generators
When the pulse generators "A" and
generator failure signal to the engine control module.
Check Area, Judgement Criteria
Pulse generator fail signal is input to the engine control module from the transaxle control
module.
Check the TCM. (Refer to GROUP
Code No. Solenoid Assy Malfunction
[Comment]
Background
The transaxle control module monitors the torque converter clutch solenoid, shift control
solenoid and pressure control solenoid.
When some one of these solenoids has failed, the transaxle control module inputs these
failure signals to the engine control module.
Check Area, Judgement Criteria
Torque converter clutch solenoid, shift control solenoid or pressure control solenoid fail
signal is input to the engine control module from the transaxle control module.
Check the TCM. (Refer to GROUP
Code No. Engine Coolant Temperature Level Input
Circuit Malfunction
[Comment]
Background
The transaxle control module uses the engine coolant temperature which is input from
the engine control module to carry out shift control.
If no engine coolant temperature signal is input from the engine control module, the transaxle
control module sends a trouble code to the engine control module.
Check Judgement Criteria
Transaxle control module (TCM) communication line trouble signal (engine coolant
temperature is not being input from engine control module) is input to the engine
control module (ECM).
