- Using a diagnostic scan tool, clear the PAM Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Operate the system and test for normal operation.
- Check the PAM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any Diagnostic Trouble Codes (DTCs) present?
Yes If DTC U0100:87 is still present, GO to N4
For all other Diagnostic Trouble Codes (DTCs), REFER to PAM DTC Chart .No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - N4 CHECK FOR DIAGNOSTIC TROUBLE CODE (DTC) U0100:00 OR DIAGNOSTIC TROUBLE CODE (DTC) U0100:87 IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.

Is DTC U0100:00 or DTC U0100:87 set in any other module?
Yes GO to N5 No GO to N6 - N5 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the PCM connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the PCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
