Is the resistance less than 5 ohms?
Yes | No |
|---|---|
GO to B13 . | REPAIR the open circuit. Clear the PCM DTCs. REPEAT the self-test. |
B12 CHECK THE INJPWR_M PID
• Ignition OFF.
• PCM Power Relay connector connected.
• PCM connector connected.
• Ignition ON, engine OFF.
• Access the PCM and monitor the INJPWR_M (VOLT) PID.
• Record the INJPWR_M PID value.
• Ignition OFF.
• Record the INJPWR_M PID value.
Is the INJPWR_M PID voltage reading above 10.5 V with ignition ON and 0 V with the ignition OFF?
Yes | No |
|---|---|
GO to B13 . | REPAIR the circuit. Clear the PCM DTCs. REPEAT the self-test. |
