Dash Integration Module (DIM)
Reverse Lockout Relay Drive: Display indicates ON when the dash integration module grounds the
control circuit of the reverse lockout relay.
Ignition 0: Display indicates ON when the ignition 0 input circuit of
the module receives a battery signal from the ignition switch
Ignition 1: Display indicates ON when the ignition 1 input circuit of
the module receives a battery signal from the ignition switch
Rear Integration Module (RIM)
Brake to Shift Output: Displays indicates ON when the body control module applies power
to the automatic transmission shift lock control power feed circuit.
Ignition 0: Display indicates ON when the ignition 0 input circuit of
the module receives a battery signal from the ignition switch
Ignition 1: Display indicates ON when the ignition 1 input circuit of
the module receives a battery signal from the ignition switch
Powertrain Control Module (PCM)
Ignition Voltage: Displays 0.0-25.5 V. This parameter is the system
voltage measured by the PCM at the PCM ignition input when the ignition switch
is in the RUN position.
IMS (Transmission Internal Mode Switch) Range: Displays Park, Park/Reverse, Reverse, Reverse/Neutral, Neutral,
Neutral/Drive 4, Drive 4, Drive 4/Drive 3, Drive 3,
Drive 3/Drive 2, Drive 2, Drive 2/Drive 1,
Drive 1, Invalid or Open. The IMS Range display represents a decoded
status of the four inputs from the IMS. This range includes all possible
in-between gear states as well as the detent gear states. The combination
of IMS inputs to the PCM are used by the PCM in order to determine what
position the manual valve is in at any time.
IMS (Internal Mode Switch) States A/B/C/P: Displays LOW or HI for the state of each of the four inputs from
the IMS. LOW displayed indicates a low voltage signal (0 volts) being
monitored at the PCM. HI displayed indicates a high voltage signal (B+)
being monitored at the PCM.
