WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
PROCEDURE
1. |
DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL |
(a) Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and branch wire.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See page ).
|
2. |
CHECK FOR OPEN IN CAN BUS WIRE (NAVIGATION RECEIVER ASSEMBLY BRANCH WIRE) |
(a) Disconnect the G37 navigation receiver assembly connector. |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection |
Switch Condition |
Specified Condition |
---|---|---|
G37-9 (CANH) - G37-10 (CANL) |
Ignition switch off |
54 to 69 Ω |

REPAIR OR REPLACE NAVIGATION RECEIVER ASSEMBLY BRANCH WIRE OR CONNECTOR (CANH, CANL) |
|
3. |
CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER ASSEMBLY - BATTERY AND BODY GROUND) |
(a) Connect the cable to the negative (-) battery terminal. NOTICE: When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See page ). |
|
(b) Disconnect the G6 and G37 navigation receiver assembly connectors.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection |
Condition |
Specified Condition |
---|---|---|
G6-7 (GND) - Body ground |

Vehicle Speed Signal Error (Test Mode DTC) (C2191/91)
DESCRIPTION
The tire pressure warning ECU receives a vehicle speed signal from the combination
meter. This DTC is stored upon entering test mode and cleared when a vehicle speed
signal of 20 km/h (12 mph) is detected for 3 seconds or more. This DTC is sto ...
Telematics Transceiver Malfunction (B15A8)
DESCRIPTION
This DTC is stored when an error in EEPROM or PLL IC is detected during the DCM
(Telematics Transceiver) self-check. The EEPROM (Electrically Erasable Programmable
Read-Only Memory) stores the various data to operate Safety Connect. The PLL IC ...
