Is the resistance greater than 10,000 ohms?

Yes

REPAIR the DLC or REPAIR the circuit in question.

No

A capacitor internal to a module can still be draining, causing irregular resistance readings. WAIT 5 minutes. REPEAT the pinpoint test. If the concern is still present, REPAIR the circuit.

Disconnect modules one at a time until the resistance is greater than 3 ohms.

ABS module C135 CCM C1582 HUD module C2395 OCSM C3043 PSCM C1463A RCM C310B SCCM C226A VDM C4396

Did the resistance change to greater than 3 ohms with one of the modules disconnected?

Yes

For the ABS module, GO to AE21 For the CCM, GO to AE23 For the HUD module, GO to AE24 For the OCSM, GO to AE26 For the PSCM, GO to AE25 For the RCM, GO to AE27 For the SCCM, GO to AE28 For the VDM, GO to AE29

No

REPAIR the circuits.
