Resistance Too High
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, pyrotechnical airbag. This could deploy the airbag!
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 driver's airbag
- the contact reel
- the SRS control module.
check for contact resistance and oxidation. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Check for loose connections. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the cable terminals in the female and male sections of the connector. The cable terminals must not be damaged or pressed back.
Check the cable between SRS control module terminals #8B (36) and #7B (35) and driver's airbag connector (green) terminals #1 and #3 for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Hint: Check the integrated capacitor in the igniter connector: Measure the resistance.
With the ignition off, connect the test instrument probes between terminals #1 and #3 on the driver's airbag connector (green). The ohmmeter reading should rise rapidly to infinity.
Reverse the position of the ohmmeter positive and negative test probes. Connect them to the connector as in the previous measurement. The ohmmeter reading should drop rapidly to approximately 0 ohms and then increase to infinity.
Disconnect the connector from the contact reel. Check the contact reel wiring by connecting an ohmmeter between terminals #1 and #2 (driver's airbag side) and driver's airbag connector (green) terminals #1 and #3. The ohmmeter should read less than 2 ohms. Take the readings again while turning the steering slowly to full lock in each direction. The ohmmeter should read less than 2 ohms for all steering wheel positions.
Remedy as necessary.

- With the ignition off and the contact reel connector disconnected, the resistance between terminals #1 and #2 on the contact reel connector (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).
