Pinpoint Test

1. Using a scan tool, perform the LTM self-test.

Is DTC B117C the only DTC present? 

1. Yes: GO to 2  .
2. No: DIAGNOSE all other LTM DTCs  first. REFER to DTC Chart: Liftgate or Trunk Module (LTM) .

1. Disconnect: Power Liftgate Latch.
2. Ignition ON.
3. Measure:

   Power Liftgate Latch Assembly			Ground
   C4339			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   6	CPR67 (VT)		-	Ground
   4	CPR68 (YE)		-	Ground

Are the voltages greater than 11 volts? 

1. Yes: INSTALL a new power liftgate latch. REFER to LIFTGATE LATCH . CLEAR the DTCs  . REPEAT the LTM self-test.

   If DTC B117C returns, GO to  5.

2. No: GO to 3  .

1. Ignition OFF.
2. Disconnect: LTM C4174B.
3. Measure:

   LTM			Ground
   C4174B			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   13	CPR67 (VT)		-	Ground
   2	CPR68 (YE)		-	Ground

Are the resistances greater than 10, 000 ohms? 

1. Yes: GO to 4  .
2. No: REPAIR the circuit in question.

1. Measure:

   LTM			Power Liftgate Chime
   C4174B			C4339
   Pin	Circuit	Measurement / Action	Pin	Circuit
   13	CPR67 (VT)		6	CPR67 (VT)
   2	CPR68 (YE)		4	CPR68 (YE)

Are the resistances less than 3 ohms? 

1. Yes: INSTALL a new power liftgate latch. REFER to LIFTGATE LATCH . CLEAR the DTCs  . REPEAT the LTM self-test.

   IF DTC B117C returns, GO to 5  .

2. No: REPAIR the circuit in question.

1. Ignition OFF.
2. Disconnect and inspect all LTM connectors.
3. 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
4. Reconnect all the LTM connectors. Make sure they seat and latch correctly.
5. Operate the system and determine if the concern is still present.

Is the concern still present? 

1. Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs  address this concern, INSTALL a new LTM. REFER to Liftgate/Trunk Module (LTM) .
2. No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
