Pinpoint Test G: DTC B10DA:86 Or DTC U0101:00

G1 CHECK THE BATTERY STATE OF CHARGE
- Ignition OFF.
- Check the battery state of charge with the battery condition test. Refer to BATTERY, MOUNTING AND CABLES .
- Does the battery pass the battery condition test?
  - Yes: GO to G2.
  - No: INSTALL a new battery. REFER to BATTERY, MOUNTING AND CABLES .
G2 CHECK FOR MODULE COMMUNICATION ON THE HS-CAN
- Connect the scan tool.
- Ignition ON.
- Carry out the network test using the scan tool.
- Is the scan tool unable to communicate with any of the modules on the HS-CAN?
  - Yes: REFER to MODULE COMMUNICATIONS NETWORK to diagnose the module that is not communicating with the scan tool.
  - No: GO to G3.
G3 INSPECT THE HS-CAN CIRCUITRY
- Ignition OFF.
- Inspect all of the HS-CAN circuitry, including the pin crimps, connector fit, corroded/bent/pushed-out/damaged pins and splice integrity in the 4 splices and 36 connections (8 connectors) between the TCM and the IPC.
- Does the HS-CAN circuitry pass the component inspection?
  - Yes: GO to G4.
  - No: REPAIR the HS-CAN circuitry as necessary. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
G4 CHECK FOR CORRECT TCM OPERATION
- Disconnect all the TCM connectors.
- Check for:
  - corrosion
  - damaged pins
  - pushed-out pins
- Connect all the TCM connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
  - Yes: INSTALL a new TCM. REFER to AUTOMATIC TRANSAXLE/TRANSMISSION - ELECTRONICALLY CONTROLLED CONTINUOUSLY VARIABLE TRANSMISSION (ECVT) . RESET the parameters in both the IPC and the TCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset . CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation. If the concern is still present, GO to G5.
  - No: The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
G5 CHECK FOR CORRECT IPC OPERATION
- Disconnect all the IPC connectors.
- Check for:
  - corrosion
  - damaged pins
  - pushed-out pins
- Connect all the IPC connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
  - Yes: INSTALL a new IPC. REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . RESET the parameters in both the IPC and the TCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset . PROGRAM the PATS keys into the new IPC. REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment . CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
  - No: The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
