Pinpoint Test Q: U3003:62 - Abs Module

• Ignition ON.
• Using a diagnostic scan tool, carry out the ABS module self-test.

Is DTC U3003:16 or U3003:17 present? 

1. Yes: For DTC U3003:16 GO to Pinpoint Test A 

   For DTC U3003:17 GO to Pinpoint Test F 

2. No: GO to Q2 

• Review the results of the previous ABS module self-test.

Is DTC U0140:00 present in the ABS module? 

1. Yes: GO to Pinpoint Test D 
2. No: GO to Q3 

• Using a diagnostic scan tool, carry out the BCM self-test.

Is DTC U3003:16 and/or U3003:17 present in the BCM? 

1. Yes: DIAGNOSE the BCM Diagnostic Trouble Codes (DTCs).

   REFER to: BODY CONTROL MODULE (BCM) .

2. No: GO to Q4 

• Measure and record the voltage at the battery.
• Using a diagnostic scan tool, observe the ABS module VPWR_ABS and the BCM V_BATT Parameter Identifications (PIDs).

Do both Parameter Identifications (PIDs) display within 0.2 volt of the recorded battery voltage? 

1. Yes: The condition that caused the DTC to set is not present at this time. The DTC may have been set due to excessive resistance at the battery terminals or in the High Speed Controller Area Network (HS-CAN).

   INSPECT the battery terminals for dirt, corrosion and other foreign material that could cause excessive resistance. VERIFY the integrity of the module connectors and wiring. REPAIR as necessary.

2. No: If the ABS module VPWR_ABS Parameter Identification (PID) does not display within 0.2 volt of battery voltage, GO to Pinpoint Test A 

   If the BCM V_BATT Parameter Identification (PID) does not display within 0.2 volt of battery voltage, DIAGNOSE the BCM.
