DTC 0502 BATTERY VOLTAGEZD30DDTi
Diagnostic Procedure (Cont'd)
EC-1147

System Description
These circuit lines are used to control the smooth shifting up and down of A/T during the hard acceleration/
deceleration.
Voltage signals are exchanged between ECM and TCM (Transmission control module).
ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.
