Step 1
- 1Disconnect the negative battery cable.
05U0TX-382 - 2Remove the knee protector, and disconnect the clock spring connectors (Orange and blue).
- 3Disconnect all D-sensor (CNT, LH and RH) connectors, and measure the resistance of each sensor.Resistance: Approx. 1.2 kΩ
05U0TX-383 - 4If not as specified, replace the sensor, then go to Step 3.
- 5If correct, go to Step 2.
Step 2
- 1Reconnect all D-sensor connectors.
05U0TX-384 - 2Disconnect the diagnostic module connector.
- 3Measure the resistance between the following terminal-wires of the diagnostic module connector and a body ground.
Step 2 Resistance check
1C (BR/G)
ResistanceApprox. 1.2 kΩ
ActionNext, check terminal-wire 1A (BR/R)
1C (BR/G)
ResistanceOther 1.2 kΩ
ActionReplace wire harness, then go to Step 3
1A (BR/R)
ResistanceApprox. 1.2 kΩ
ActionNext, check terminal-wire 2L (BR/B)
1A (BR/R)
ResistanceOther 1.2 kΩ
ActionReplace wire harness, then go to Step 3
2L (BR/B)
ResistanceApprox. 1.2 kΩ
ActionGo to Step 3
2L (BR/B)
ResistanceOther 1.2 kΩ
ActionReplace wire harness, then go to Step 3
Step 3
- 1Reconnect the diagnostic module connector.
- 2Reconnect the clock spring connector.
- 3Reconnect the negative battery cable.
- 4Turn the ignition switch ON, and monitor the warning lamp operation.
05U0TX-385 - 5If the warning lamp flashes ten times again, replace the diagnostic module.
