DIAGNOSTIC CODE 7-6 Test 4 Checking for an internal short to ground, or voltage in the pump
Do not check continuity between Deutsch pins A, E and F.
If there is continuity with another pin, continue with the next step. If there is no continuity, proceed to Test 8. 2. Visually inspect the pins and crimps in injection pump harness for the cause of the open.
If there is a repairable condition, repair. Retest to be sure the problem has been corrected. Figure 281 — Continuity between Deutsch Pin A and Pins B, C, D, G, H and J (example)
1. Check continuity: Choose one of the following pins: Deutsch pin A, E or F. Check continuity between the pin you chose and each of the remaining pins (not including the original three selected) on the pump connector (one at a time). For example, if you choose pin A, check continuity between pin A and pins B, C, D, G, H, and J; but not between pin A and pins E or F. Also check continuity between the pin you chose and the case.
If there is not a repairable condition, send the pump to a certified pump shop for repair of the pump or integral jumper harness. Then retest to be sure the problem has been corrected.
