Toyota Corolla (E120): Ecm/pcm processor
Dtc p0606 ecm/pcm processor
Monitor description
The ecm continuously monitors its internal circuits. This self–check insures that the ecm is functioning properly.
If a malfunction is detected, the ecm will set the appropriate dtc and illuminate the mil.
The two cpus, main and sub cpu inside the ecm, perform continuous mutual monitoring. If there is difference between outputs from the two cpus that deviates from standard level ranges, the ecm concludes that there is a fault and sets a dtc.

Inspection procedure
Hint
: read freeze frame data using the hand-held tester or the obd ii scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air–fuel ratio was lean or rich, etc. At the time of the malfunction.

Circuit description
The speed sensor detects wheel speed and transmits the appropriate
signals to the ecu. These signals are used for control
of the abs control system. Each of the front and rear rotors has
48 serrations.
When the rotors rotate, the magnetic field generated by the permanent
magnet in the spe ...
On–vehicle inspection
1. Inspect brake booster
Airtightness check.
Start the engine and stop it after 1 or 2 minutes. Depress
the brake pedal several times slowly.
Hint:
if the pedal goes down farthest at the 1st time, but gradually
rises after the 2nd or 3rd time, the booster is airtight.
