Resistance Too High. Intermittent Fault

Resistance too high. Intermittent fault

Intermittent fault




- Ignition off.

Warning! Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected non-deployed pyrotechnic seat belt tensioner. This could deploy the seat belt tensioner!

Caution! Do not touch the terminal pins in the SRS control module. There is a risk of static discharge. This could damage the SRS control module.

Check the connectors for the SRS module and seat belt tensioner for contact resistance and oxidation according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults and for loose connections according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the female and male parts of the connectors for the SRS control module and the seat belt tensioner. The cable terminals must not be damaged or pressed back.
Check the cable between the SRS and the terminal of the seat belt tensioner connector according to the following:

for diagnostic trouble code (DTC) SRS-0064,
front left seat belt tensioner terminals #5A(5), #6A(6) and connector terminals #1, #3.

for diagnostic trouble code (DTC) SRS-006C,
front right seat belt tensioner terminals #5C(1), #6C(2) and connector terminals #1, #3.

for diagnostic trouble code (DTC) SRS-0074,
rear left seat belt tensioner terminals #16A(16), #15A(15) and connector terminals #1, #3.

for diagnostic trouble code (DTC) SRS-007C,
center rear seat belt tensioner terminals #17A(17), #18A(18) and connector terminals #1, #3.

for diagnostic trouble code (DTC) SRS-0084,
rear right seat belt tensioner terminals #16C(12), #15C(11) and connector terminals #1, #3.
for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Remedy as necessary.

Other information:
- To access / replace the SRS control module and connector, see Supplemental restraint system module (SRS), replacing Service and Repair.
- To access the connector for the seat belt tensioner, see Seat belts, replacing Seat Belts, Replacing.
- To connect the breakout box, see Connecting the breakout box Connecting the Breakout Box, Supplemental Restraint System Module (SRS).
- With the ignition off and the seat belt tensioner connector disconnected, the resistance between the seat belt tensioner connector terminals #1 and #3 (SRS control module side) should be approximately 22 kohms.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).

Do you want to view the information again?

Yes - Attempt New Test

No - Exit fault-tracing
