1 |
Was “Engine and Emission Control System Check” performed?
|
Go to Step 2.
|
|
2 |
Starter signal check
1)
Start engine, measure voltage between “E119-35” terminal of ECM connector and vehicle body ground.
Is voltage 0 – 1 V?
|
Intermittent trouble. Check for intermittent referring to
Intermittent and Poor Connection Inspection
. If OK, substitute a known-good ECM and recheck.
|
Go to Step 3.
|
3 |
Wire circuit check
2)
Check for proper connection to relay box at “BLK/YEL”, “BLK/RED” and “BLK” wire terminals.
3)
Disconnect connectors from starting motor.
4)
Measure voltage between “E119-35” terminal of ECM connector and vehicle body ground with ignition switch turned ON.
Is voltage 0 – 1 V?
|
Go to Step 4.
|
For A/T vehicle, “BLK/YEL” or “BLK/RED” wire shorted to power circuit.
For M/T vehicle, “BLK/YEL” wire shorted to power circuit.
If wires are OK, substitute a known-good ECM and recheck.

4 |
Wire circuit check
1)
Measure voltage between “BLK/RED” wire terminal of relay box connector and vehicle body ground with ignition switch turned ON.
Is voltage 0 – 1 V?
|
Replace relay box. If OK, substitute a known-good ECM and recheck.
|
Faulty ignition switch, check ignition switch referring to
Ignition Switch Inspection
. If ignition switch is OK, check “BLK/YEL” and/or “BLK/RED” wire (between ignition switch and relay box) for short to power circuit.
