Test 13B - Bus Short To Battery
- Turn ignition off. Using external ohmmeter, measure resistance between terminals C11 (Yellow/Red wire) and C30 (Violet/Brown wire) on Powertrain Control Module (PCM) Gray connector. PCM is located at right corner of firewall. If resistance is less than 5 ohms, repair short between Yellow/Red wire and Violet/Brown wire. If resistance is 5 ohms or greater, go to next step.
- Measure resistance between terminals C11 (Yellow/Red wire) and C28 (White/Black wire) on PCM Gray connector. If resistance is less than 5 ohms, repair short between Yellow/Red wire and White/Black wire. If resistance is 5 ohms or greater, replace PCM.
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.
