Test 13C - Bus Short To Battery
- Turn ignition off. Using external ohmmeter, measure resistance between terminals No. 3 (Violet/Brown wire) and No. 4 (Yellow wire) on Compass Mini-Trip Computer (CMTC) connector. If resistance is less than 5 ohms, repair short between Violet/Brown wire and Yellow wire. If resistance is 5 ohms or greater, go to next step.
- Measure resistance between terminals No. 4 (Yellow wire) and No. 5 (White/Black wire) on CMTC connector. If resistance is less than 5 ohms, repair short between Yellow wire and White/Black wire. If resistance is 5 ohms or greater, go to next step.
- Using scan tool in ohmmeter mode, measure resistance at terminal No. 2 (Black wire) on CMTC connector. If resistance is 5 ohms or greater, repair open Black wire. If resistance is less than 5 ohms, replace CMTC.
NOTE:
For connector terminal identification, refer to CONNECTOR IDENTIFICATION
. For wiring diagrams, refer to WIRING DIAGRAMS
. After each repair, perform TEST VER-1A
.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
