Powertrain Control Module (PCM) C175
| Pin Number (s) | Circuit Designation/Description | Normal Condition/Measurement |
|---|---|---|
| 20 | 585 (VT) Generator monitor (GEN MON). | This circuit is for serial communication and is pulse width modulated (PWM). Any testing of this circuit would be for an open, short to ground or short to power. Both ends of the circuit must be disconnected before testing may occur. |
| 45 | 586 (RD/PK) Generator communication (GEN COM). | This circuit is for serial communication and is pulse width modulated (PWM). Any testing of this circuit would be for an open, short to ground or short to power. Both ends of the circuit must be disconnected before testing may occur. |
