Important Information

Propulsion Control Module (PCM) Overview

IMPORTANT: Refer also to Section 2B ‑ PCM 112 and Engine Control Overview.
The propulsion control module requires 9.5 VDC minimum to operate. If the PCM should fail, the engine will stop running.
The inputs to the PCM can be monitored and tested by using the computer diagnostic system (CDS G3).
CDS G3 Interface Kit
The PCM controls the following functions and components:
• Electronic shift control
• Electronic throttle control
• Main power relay

66165
Measures RPM on spark ignition (SI) engines, ohms, amperes, AC and DC
voltages; records maximums and minimums simultaneously, and accurately
reads in high RFI environments.
4516
Provides a visual indication of spark/coil efficiency.
7513
Tests the fuel pump pressure; can be used to relieve fuel pressure.
2807
Test probes adapt test meter leads to harness connections without damaging
harness terminals. May be used with Computer Diagnostic System (CDS).
