Tundra 2WD V6-4.0L (1GR-FE) (2005)
Resistance: 10 kOhms or higher
HINT: Measure the resistance while lightly shaking the wire harness vertically and horizontally.
5. VISUAL CHECK AND CONTACT PRESSURE CHECK
a. Disconnect the connectors at both ends.
b. Check for rust or foreign material, etc. in the terminals of the connectors.
c. Check crimped portions for looseness or damage and check that the terminals are secured in the lock portion.
HINT: The terminals should not come out when pulled lightly from the back.
d. Prepare a test male terminal and insert it in the female terminal, then pull it out.
NOTE: When testing a gold-plated female terminal, always use a gold-plated male terminal.
HINT: If a test terminal is pulled out more easily than others, there may be poor contact in that section.
6. CHECK OPEN CIRCUIT
For an open circuit in the wire harness in Fig. 1, perform a continuity check (step (a) below) or a voltage check (step (b) below).
a. Check the continuity.
1. Disconnect connectors A and C and measure the resistance between them.
In the case of Fig. 2:
Between terminal 1 of connector A and terminal 1 of connector C -> 10 kOhms or higher (open)
Between terminal 2 of connector A and terminal 2 of connector C -> Below 1 Ohms
An open circuit exists in the wire harness between terminal 1 of A and terminal 1 of C.
