DTC is Not Output from Diagnostic Output Terminal (For Vehicle Not Equipped with Air Bag System)
Wiring Diagram
1. Main fuse 4-1. Ground terminal
2. Main relay 4-2. Diagnostic output terminal
3. Immobilizer Control Module 5. To ECM
4. Immobilizer diagnostic coupler (Vehicle not equipped with immobilizer indicator lamp) [A]: In cabin
Troubleshooting
Step Action YES NO
1
1) Check voltage between “G38-2” terminal and body ground with ignition switch turned ON.
Is it 10 – 14 V?
Go to Step 2.
“B1/B” wire open.
2
1) Connect voltmeter between “G38-10” terminal and body ground.
Does voltmeter indicator deflect?
Go to Step 3.
Poor “G38-2”, “G38-10” or “G38-8” connection. “B” wire of “G38-8” terminal open. “P/G” wire between “G38-10” terminal and diagnostic output terminal of immobilizer diagnostic coupler short. If wire and connections are OK, substitute a known-good Immobilizer Control Module and recheck. See NOTE.
3
1) Connect voltmeter between diagnostic output terminal of immobilizer diagnostic coupler and body ground.
Is it possible to read DTC by checking deflection of voltmeter indicator?
“B” wire of ground terminal for immobilizer diagnostic coupler open.
“P/G” wire between “G38-10” terminal and diagnostic output terminal of immobilizer diagnostic coupler open.
NOTE:
After replacing with a known-good Immobilizer Control Module, register ECM/Immobilizer Control Module code in ECM and Transponder code and ECM/Immobilizer Control Module code in Immobilizer Control Module by performing procedure described in Procedure after Immobilizer Control Module Replacement:M13A Model .
