*NO CRANK CONDITION (CONTINUED) 3. EXCESSIVE RESISTANCE IN THE BATTERY CIRCUIT Turn the ignition off. Check the Battery Cables for excessive resistance using the service information procedure. Did either Battery Cable have a voltage drop greater than 0.2 of a volt? Yes >> Repair the excessive resistance in the Battery circuit. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) No >> Go To 4 4. STARTER RELAY Turn ignition off. Remove the Starter Relay from IPM. CAUTION: The Parking Brake must be on and the Transmission must be in park for a vehicle equipped with WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands Did the Starter Motor crank the engine? Yes >> Go To 5 No >> Go To 7 5. (F924) FUSED IGNITION SWITCH OUTPUT CIRCUIT Ignition on, engine not running. Using a 12-volt test light, probe the (F924) Fused Ignition Switch Output circuit in the Starter Relay connector. While observing 12-volt test light, hold ignition key in the start position. Does the test light illuminate brightly? Yes >> Go To 6 No >> Repair the excessive resistance in the (F924) Fused Ignition Switch Output circuit. Inspect related fuses and repair as necessary. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) 6. (T752) STARTER RELAY CONTROL CIRCUIT OPEN Turn the ignition off. Remove the Starter Relay from the IPM. Disconnect the C3 PCM harness connector. Measure the resistance in the (T752) Starter Relay Control circuit from the Relay terminal to the appropriate termi- Is the resistance below 5.0 ohms? Yes >> Replace the Starter Motor Relay. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) No >> Repair the open in the (T752) Starter Relay Control circuit. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) HB ENGINE ELECTRICAL DIAGNOSTICS 9 - 1051 |
