Pinpoint Test L: U0100:00
- L1 VERIFY THAT A VEHICLE SESSION CAN BE ESTABLISHED USING THE DIAGNOSTIC SCAN TOOL
- Ignition ON.
- Verify that a vehicle session can be established using a diagnostic scan tool.
Can a vehicle session be established?
Yes GO to L2 No REPAIR the communication fault. REFER to: Communications Network . - L2 RECHECK THE PAM (PARKING ASSIST CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Ignition ON.
- Using a diagnostic scan tool, clear the PAM Diagnostic Trouble Codes (DTCs).
- Operate the system and test for normal operation.
- Check the PAM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0100:00 present?
Yes GO to L3 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. - L3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the PCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes Refer to the appropriate Engine article for the procedure. No GO to L4 - L4 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0100:00 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Wait 10 seconds.
- Ignition ON.
- Using a diagnostic scan tool, retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0100:00 set in other modules?
Yes GO to L5 No GO to L6 - L5 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all PCM and related in-line 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 and related in-line connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
