THIS DOCUMENT SUPERSEDES THE RETAILER TECHNICAL JOURNALS 19468 and 19316, DATED 07-29-2008 and 07-01-2008 respectively. RTJ 19468 is for parts information and this information can be found in VIDA as well as in this RTJ. RTJ 19316 is no longer valid and the new information can be found in VIDA as well as in this RTJ. PLEASE UPDATE YOUR FILES.
DESCRIPTION:
The purpose of this RTJ is to update the information concerning the criteria to switch off the low tire pressure message and give some additional basic information about the TPMS system and thereby help in fault tracing in order to take the right corrective actions.
TPMS description:
TPMS is a monitoring system for the driver to keep the right tire pressure in the tires. The sensors begin transmitting the signals to the Upper Electronic Module (UEM) when the vehicle's speed is higher than 40 km/h (25mph).
The driver will get a message in the Driver Information Module (DIM) if the tire pressure drops a certain percentage from the recommended tire pressure. Recommended tire pressure is present in the owner's manual and in the fuel filler lid (model specific).
If vehicles with TPMS are driven with the "comfort pressure" set there will be unnecessary tire pressure warnings to the driver (in the DIM) in cold weather conditions. Volvo does not recommend using comfort pressures due to the sensitivity of TPMS.
Criteria to switch on the low tire pressure message:
^ The tire pressure has dropped more that 22% of the recommended pressure see the Table 1 in the attached document.
Criteria to switch off the low tire pressure message:
^ The tire pressure must the filled up at least to 95% of the recommended pressure AND then the vehicle needs to be driven for 5 minutes at a speed higher than 40 km/h (25mph).
OR
^ Fill the pressure to at least 95% of the recommended pressure with ignition on.
Fault tracing:
^ Fault trace according to VIDA by using CSC LI this will guide you to a smart tool that will help you to find the faulty sensor.
OR
^ Use Diagnostic/reference information/UEM and the stored DTC in VIDA.
Note!
When using the special tool to ping the sensor make sure that the tool used matches the tool in the attachment (see Photo 1).
MATERIALS:
A snap-in transmitter has been introduced during structure week 2007W48 in production. This part can be used on all cars that are fitted with Schrader style TPMS (all vehicles in this RTJ).
PN 30748991 = Old PN before 2007W48
PN 31200923 = New PN after 2007W48
SERVICE:
If a customer claims of having a "Low tire pressure warning" message in the DIM fill the tire pressure to the recommended pressure and make a test drive with the criteria above.
