TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2176/76: Receiver Error
C2176/76 - Receiver Error
DESCRIPTION
The signals are transmitted to the tire pressure warning antenna and receiver on the body as radio waves and then sent to the tire pressure warning ECU.
WIRING DIAGRAM
INSPECTION PROCEDURE
NOTICE:
* When replacing the tire pressure warning ECU, read the IDs stored in the ECU using Techstream and write them down before removal.
* It is necessary to perform initialization Initialization after registration Registration of the transmitter IDs into the tire pressure warning ECU after the ECU have been replaced.
PROCEDURE
1. CHECK TIRE PRESSURE WARNING ECU
(a) Measure the voltage according to the value(s) in the table below.
Standard voltage:
NG -- CHECK HARNESS AND CONNECTOR (ECU - RECEIVER)
OK -- Continue to next step.
2. CHECK WIRE HARNESS (ECU - RECEIVER)
(a) Disconnect the E60 ECU connector.
(b) Disconnect the N34 receiver connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. REPLACE TIRE PRESSURE WARNING ANTENNA AND RECEIVER
NEXT -- Continue to next step.
4. CHECK DTC
(a) Check for DTC Reading and Clearing Diagnostic Trouble Codes.
OK:
DTC is not output.
HINT
* It is necessary to register IDs when replacing the tire pressure warning ECU Registration.
* Read the IDs on the DATA LIST before removing the tire pressure warning ECU. Register the ID in the new tire pressure warning ECU.
NG -- REPLACE TIRE PRESSURE WARNING ECU
OK -- END
5. CHECK HARNESS AND CONNECTOR (ECU - RECEIVER)
(a) Disconnect the E60 ECU connector.
(b) Disconnect the N34 receiver connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
Result:
C -- REPAIR OR REPLACE HARNESS OR CONNECTOR AND REPLACE TIRE PRESSURE WARNING ECU
A -- REPLACE TIRE PRESSURE WARNING ECU
B -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
