HA7 - Check Resistance of Injector(s) and Harness - MFI Engines

- Key "OFF".

- Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.

NOTE: This erases the continuous memory.

- Install breakout box, leave PCM disconnected.

- Measure resistance of injector bank 1 between test pin 37 and test pin 58 at the breakout box. Record resistance.

- Measure resistance of injector bank 2 between test pin 37 and test pin 59 at the breakout box. Record resistance.

- Refer to Injector Resistance Specification Table 1.

- Is each resistance within specification?

Yes -- Go to HA12. HA12 - Check Injector Driver Signal

No -- Go to HA9. HA9 - Check Continuity of Fuel Injector Harness
