Sequoia 2WD V8-4.6L (1UR-FE) (2010)
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 the 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: Testing and
Inspection/Programming and Relearning.
NEXT -- Continue to next step.
2. CHECK FOR SHORT TO GND IN CAN BUS WIRE (DLC3 BRANCH WIRE)
(a) Disconnect the H93 No. 1 junction connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPAIR OR REPLACE CAN BRANCH WIRE CONNECTED TO DLC3
OK -- Continue to next step.
3. CONNECT CONNECTOR
(a) Reconnect the H93 No. 1 junction connector.
NEXT -- Continue to next step.
4. CHECK FOR SHORT TO GND IN CAN BUS WIRE (NO. 2 JUNCTION CONNECTOR SIDE)
