TERMINALS OF ECU

1. COMBINATION METER ASSEMBLY

(a) Measure the voltage and resistance according to the value(s) in the table below.

- *1: for Manual Transmission
- *2: w/ Cruise Control
- *3: for Hydraulic Booster Type
- *4: for U.S.A.
- *5: w/ Active Traction Control
- *6: for A750E and A750F Automatic Transmission
