DR - Testing Notes


DESCRIPTION
The Powertrain Control Module (PCM) uses the Cylinder Identification (CID) signal information for fuel injector synchronization. The CID signal is generated by a hall-type Camshaft Position (CMP) sensor with a 50% duty cycle and an amplitude that varies from 0.4 volts to B(+).

NOTE
You should enter this Pinpoint Test only when you have been directed here from Diagnostic Routines.

REMEMBER
This Pinpoint Test is intended to diagnose only the following:

- Harness circuits: CID(+), CID(-), CID, SIG RTN, VPWR

- CMP sensor

- PCM
