Pinpoint Test 2

PINPOINT TEST 2: THE RESTRAINT CONTROL MODULE (RCM) DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

Step 1 - 2:

Normal Operation
The RCM communicates with the diagnostic tool through the ISO 9141 communications network circuit (LB/W). If circuit (LB/W) becomes open or shorted to ground, communications to that module will not be possible. Check circuit (LB/W) between the RCM 0810-101 and the DLC D-01. Total resistance values must not be more than 5 Ohms. If the resistance is more than 5 Ohms there is an open in the ISO network circuit, damage to the DLC D-01, or damage to the 0810-101.

Possible Causes
- ISO 9141 network circuit (LB/W) shorted to ground or open
- DLC D-01
- RCM 0810-101
- RCM
