Pinpoint Test C : U201F:31
- C1 CHECK FOR COMMUNICATION WITH THE TPM MODULE
- Using a scan tool, perform network test.
Does the TPM module pass the network test?
Yes GO to C2. No REFER to Module Communications Network . - C2 CHECK THE TPM MODULE COMMUNICATION CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: TPM Module.
- Disconnect: RFA Module C2153E.
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C3641-3 Ground
Is any voltage present?
Yes REPAIR the circuit. No GO to C3. - C3 CHECK THE TPM MODULE COMMUNICATION CIRCUIT FOR AN OPEN OR SHORT TO GROUND
- Ignition OFF.
- Measure:
Positive Lead Measurement / Action Negative Lead C3641-3 Ground
Is the resistance less than 3 ohms between the TPM module and the RFA module; and greater than 10, 000 ohms between the TPM module and ground?
Yes INSTALL a new TPM module. REFER to Tire Pressure Monitoring System (TPMS) . CLEAR the DTCs. REPEAT the TPM module self-test. If the concern is still present, GO to C4. No REPAIR the circuit. - C4 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect and inspect all the RFA module connectors.
- Repair:
- corrosion (replace connector or terminals - clean module pins)
- damaged or bent pins - replace terminals/pins
- pushed-out pins - replace pins as necessary
- Connect all the RFA module connectors. Make sure they seat and latch correctly.
- Operate the system and verify the concern is still present.
Is the concern still present?
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 RFA module. REFER to Multifunction Electronic Modules . 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.
