Possible Causes

(A14) PCM FUSED B+ CIRCUIT

(A41) PCM FUSED IGNITION SWITCH OUTPUT CIRCUIT

(Z12) PCM GROUND CIRCUITS

DIAGNOSTIC PROCEDURE - CHECKING PCM POWER AND GROUND CIRCUIT

TEST ACTION
1
NOTE: The battery must be fully charged before continuing.
Turn the ignition off.Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Using a 12-volt test light connected to ground, probe the (A14) PCM Fused B+ circuit in the Pinout Box.Does the test light illuminate brightly?
  1. Yes --> Go To 2
  2. No --> Repair the (A14) Fused B+ circuit.

    Perform POWERTRAIN VERIFICATION TEST VER - 1 NGC .
2 Turn the ignition off.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.

Turn the ignition on.
Using a 12-volt test light connected to ground, probe the (A41) PCM Fused Ignition Switch Output circuit in the Pinout Box.
Does the test light illuminate brightly?
  1. Yes --> Go To 3
  2. No --> Repair the (A41) Ignition Switch Output circuit

    Perform POWERTRAIN VERIFICATION TEST VER - 1 NGC .
3 Turn the ignition off.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.

Using a 12-volt test light connected to battery voltage, probe the (Z12) PCM ground circuits in the Pinout Box.
Does the test light illuminate brightly?
  1. Yes --> Test Complete.
  2. No --> Repair the (Z12) PCM ground circuits.

    Perform POWERTRAIN VERIFICATION TEST VER - 1 NGC .
