Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
---|---|---|---|---|
Passenger Air Bag OFF Indicator Control | B0680 02 | B0680 04 | B0680 01 | - |
Passenger Air Bag ON Indicator Control | B067F 02 | B067F 04 | B067F 01 | - |
Passenger Air Bag Disable Indicator Ground | - | B067F 04, B0680 04 | 1 | -- |
The passenger air bag ON/OFF indicators are used to notify the driver when the passenger presence system has enabled or disabled the passenger instrument panel air bag. When the ignition is turned ON, the ignition voltage is supplied to the passenger presence module. When the inflatable restraint sensing and diagnostic module (SDM) receives the appropriate serial data message from the passenger presence module the SDM will then provide voltage to the appropriate indicator.
• | The Vehicle is in Service mode |
• | Ignition Voltage is between 9-16 V |
The SDM detects improper voltage on the control circuit of the passenger air bag ON or OFF indicator
Passenger air bag ON and OFF indicators are disabled.
The condition for setting the DTC no longer exists.
SIR System Description and Operation
Control Module References for scan tool information
Note: The passenger air bag ON and OFF indicators may not operate as expected if there are supplemental inflatable restraint (SIR) DTCs. Repair all SIR DTCs before proceeding with this diagnostic.
Note: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected. • Passenger air bag disable on/off indicator. • Passenger air bag disable on/off indicator wiring harness.
If 10 Ω or greater
Repair the open/high resistance in the circuit.
If less than 10 Ω
If 11 V or greater
3.1. | Ignition OFF. Disconnect the X1 harness connector at the K36 SDM. Ignition ON. |
3.2. | Test for less than 1 V between the control circuit and ground. |
If 1 V or greater, repair the short to voltage on the circuit.
If less than 1 V, replace the K36 SDM.
If less than 11 V
If 4 V or less
5.1. | Ignition OFF. Disconnect the X1 harness connector at the K36 SDM. |
5.2. | Test for infinite resistance between the control circuit and ground. |
If less than infinite resistance, repair the short to ground on the circuit.
5.3. | Test for less than 2 Ω in each control circuit end to end. |
If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, replace the K36 SDM.
If greater than 4 V
If 11 V or greater
7.1. | Ignition OFF. Disconnect the X1 harness connector at the K36 SDM. Ignition ON. |
7.2. | Test for less than 1 V between the control circuit and ground. |
If 1 V or greater, repair the short to voltage on the circuit.
If less than 1 V, replace the K36 SDM.
If less than 11 V
If 4 V or less
9.1. | Ignition OFF. Disconnect the X1 harness connector at the K36 SDM. |
9.2. | Test for infinite resistance between the control circuit and ground. |
If less than infinite resistance, repair the short to ground on the circuit.
9.3. | Test for less than 2 Ω in each control circuit end to end. |
If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, replace the K36 SDM.
If greater than 4 V
Perform the Diagnostic Repair Verification after completing the repair.
