HOW TO TROUBLESHOOT ECU CONTROLLED 

SYSTEMS

2005 CELICA   (RM1131U)

(2)

Disconnect connector ”B” and measure the resis-
tance between terminal 1 of connector ”A” and body
ground, and terminal 1 of connector ”B2” and body
ground.
In the case of Fig. 7:
Between terminal 1 of connector ”A” and body
ground 

→

 No continuity

Between terminal 1 of connector ”B2” and body
ground 

→

 Continuity (short)

Therefore, it is found out that there is a short circuit
between terminal 1 of connector ”B2” and terminal
1 of connector ”C”.

8.

CHECK AND REPLACE ECU

First check the ECU ground circuit. If it is faulty, repair it. If it is
normal, the ECU could be faulty, so replace the ECU with a nor-
mal functioning one and check that the symptoms appear.

(1)

Measure the resistance between the ECU ground
terminal and the body ground.

Resistance: 1 

Ω

 or less

(2)

Disconnect the ECU connector, check the ground
terminals on the ECU side and the wire harness
side for bend and check the contact pressure.
