Diagnosing Low Line TPMS
Diagnosing TRW/Lear Low Line Tire Pressure Monitoring warning light ON conditions with certain Diagnostic Trouble Codes stored in Memory
requires particular attention. The following procedure can assist in proper diagnosis for the wheel sensor concerns.
^ Install TPMS tool to diagnose DTC's, retrieve DTC C1313, C1312, etc.
^ Select "Current Data" on the TPMS tool.
^ Using the worksheet record sensor ID for all Four (4) Sensors from the "Current data" Screen.
^ Ping each wheel and record these sensor ID's on the worksheet.
^ Match wheel sensor ID, against the ID recorded from the exciter tool/ECU. The missing sensor ID should be checked for correct setting and battery
level, replace sensor if necessary.
NOTE:
DO NOT replace or diagnose components in a position based on the DTC information. Always locate the sensor ID on the vehicle with the hand-tool. A
commen mistake is Code C1312 is set and the technical replaces that sensor thinking it was in the left Front, the wheel and tire may be located in the
Right Rear. When and it the tires are rotated the original configuration is no longer valid.
