The Time is Incorrect [10/2023 - ]: Procedure

  1. CHECK FOR OPEN IN CAN BUS WIRE 
    1. Disconnect the G167 clock assembly connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition Resistance: Malfunction
      G167-4 (TX+1) - G167-5 (TX-1) Cable disconnected from negative (-) auxiliary battery terminal 54 to 69 Ω Below 53 Ω: Short in line
      Higher than 70 Ω: Open in CAN main bus line
      G167-4 (TX+1) - Body ground Cable disconnected from negative (-) auxiliary battery terminal 200 Ω or higher Below 200 Ω: Ground short
      G167-5 (TX-1) - Body ground Cable disconnected from negative (-) auxiliary battery terminal 200 Ω or higher Below 200 Ω: Ground short
      G167-4 (TX+1) - +B Cable disconnected from negative (-) auxiliary battery terminal 6 kΩ or higher Below 6 kΩ: +B short
      G167-5 (TX-1) - +B Cable disconnected from negative (-) auxiliary battery terminal 6 kΩ or higher Below 6 kΩ: +B short

      Result

  2. CHECK FOR OPEN IN CAN BUS WIRE 
    1. Disconnect the G169 central gateway ECU (network gateway ECU) connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      G169-10 (CAVH) - G167-4 (TX+1) Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω
      G169-5 (CA8H) - G167-4 (TX+1) Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω
      G169-11 (CAVL) - G167-5 (TX-1) Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω
      G169-6 (CA8L) - G167-5 (TX-1) Cable disconnected from negative (-) auxiliary battery terminal Below 1 Ω

      Result

      Proceed to
      OK
      NG

    Result: 

    OK 

    REPLACE CENTRAL GATEWAY ECU (NETWORK GATEWAY ECU). Refer to  REMOVAL [10/2023 - ] 

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

  3. CHECK FOR SHORT TO GND IN CAN BUS WIRE 
    1. Disconnect the G169 central gateway ECU (network gateway ECU) connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      G167-4 (TX+1) - G167-5 (TX-1) Cable disconnected from negative (-) auxiliary battery terminal 200 Ω or higher
