RESTRAINT CONTROL SYSTEM 9J1–33 DTC 21 Driver Deployment Loop Resistance High Step Action Yes No 1 Was the “SRS Diagnostic System Check" performed? Go to Step 2 Go to the “SRS Diagnostic System Check." 2 1. When measurements are requested in this chart use 5– 8840–0285–0 DVM with correct terminal adapter from 5– 2. Use scan tool data list function, read and record the driver deployment loop resistance. Is driver deployment loop resistance more than 4.4 ohms? Go to Step 3 Go to Chart A. 3 1. Ignition switch “OFF." 2. Disconnect driver air bag assembly yellow 2–pin connector located at base of steering column is seated properly. Is the 2–pin connector connected properly? Go to Step 4 Seat SRS coil assembly 2–pin connector properly. Go to Step 8 4 1. Disconnect and inspect the SRS coil assembly yellow 2–pin connector located base of steering column. 2. If OK, reconnect the SRS coil assembly yellow 2–pin connector. 3. Ignition switch “ON." Is DTC 21 current? Go to Step 5 Ignition switch “OFF." Go to Step 8 5 1. Ignition switch “OFF." 2. Disconnect SRS coil and passenger air bag assembly yellow 2–pin connectors located at the base of steering column and 3. Connect SRS driver / passenger load tool 5–8840–2421–0 and appropriate adapter to SRS coil and passenger air bag 4. Ignition switch “ON." Is DTC 21 current? Go to Step 6 Go to Step 7 6 1. Ignition switch “OFF." 2. There has been a increase in the total circuit resistance of the driver deployment loop. 3. Use the high resolution ohmmeter mode of the DVM while checking CKTs IB05–YEL/IB06–YEL/BLK, and SDM Was a fault found? Replace SRS harness. Go to Step 8 Go to Chart A. 7 1. Ignition switch “OFF." Disconnect SRS driver / passenger load tool from SRS coil Is DTC 21 current? Ignition switch “OFF." Replace SRS COIL ASSEMBLY. Refer to in this section. Go to Step 8 Ignition switch “OFF." Replace driver air bag assembly. Go to Step 8 8 Reconnect all components, ensure all component are properly mounted. Clear diagnostic trouble codes. Repeat the “SRS Diagnostic System Check." Go to Step 8. |
