G7 CHECK THE GENERATOR MONITOR CIRCUIT FOR AN OPEN
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C175B-26 | C102B-1 |
Is the resistance less than 3 ohms?
Yes | GO to G8 |
|---|---|
No | REPAIR the circuit. |
G8 CHECK THE GENERATOR B+ INTERNAL RESISTANCE
Disconnect Generator C102B. Disconnect Generator C102C. Measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
Generator B+ Terminal | Generator case |
Is the resistance greater than 25K ohms?
Yes | GO to G9 |
|---|---|
No | INSTALL a new generator. REFER to: Generator - 5.0L 32V Ti-VCT (414-02 Generator and Regulator, Removal and Installation). |
G9 CHECK THE RESISTANCE OF THE VOLTAGE REGULATOR INTERNAL CIRCUITS
Measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
Generator pin 1 (Component Side) | Generator case | |
Generator pin 2 (Component Side) | Generator case | |
Generator pin 3 (Component Side) | Generator case |
Are the resistances greater than 10,000 ohms?
Yes | GO to G10 |
|---|---|
No | INSTALL a new generator. REFER to: Generator - 5.0L 32V Ti-VCT (414-02 Generator and Regulator, Removal and Installation). |
G10 COMPARE THE GENMON PID (PARAMETER IDENTIFICATION) AND THE GENCMD PID (PARAMETER IDENTIFICATION)
Connect PCM C175B. Connect a fused jumper wire:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C102B-1 | C102B-2 |
Start the engine. Using a diagnostic scan tool, view PCM Parameter Identifications (PIDs). Using the active command, set the PID GENVDSD to 14 volts. Monitor the PCM Parameter Identifications (PIDs) GENMON and GENCMD. Perform a wiggle test of the generator wiring and connections.
Do the Parameter Identifications (PIDs) read within 5% of each other?
Yes | REMOVE the fused jumper wire. INSTALL a new generator. REFER to: Generator - 5.0L 32V Ti-VCT (414-02 Generator and Regulator, Removal and Installation). |
|---|---|
No | REMOVE the fused jumper wire. GO to G11 |
