Pinpoint Test D: VAPS Module & Harness Check

VAPS Harness Connector Check

Ensure ignition is off. Disconnect connector from control module. Connect ohmmeter between circuit No. 57 (Black wire) and ground. Check resistance. If resistance is less than 15 ohms, go to next step. If resistance is greater than 15 ohms, repair harness and repeat step 1).

VAPS Harness and Connector Check

Remove VAPS connector from module. Connect voltmeter ground lead to circuit No. 57 (Black wire). Turn ignition on. Check and record voltage at each terminal in connector. See VAPS HARNESS CIRCUIT VOLTAGE .

If voltage in each circuit is not as specified, repair harness as necessary and repeat step 2). If voltage in each circuit is as specified, go to next step.

VAPS Harness and Connector Test

Turn ignition off. Using ohmmeter, check and record resistance between ground circuit No. 57 (Black wire) and each remaining circuit. See VAPS HARNESS CIRCUIT RESISTANCE .

VAPS HARNESS CIRCUIT RESISTANCE

Circuit No. (Wire Color)	Function	Ohms
200 (Brown)	Diagnostic	Open
298 (Purple/Orange)	Power	3.6
495 (Tan)	Actuator	Open
496 (Orange)	Actuator	Open
497 (White)	Actuator	Open
498 (Pink)	Actuator	Open
606 (White/Light/Blue)	Diagnostic	Open
676 (Pink/Orange)	Speed Sensor	0.6
679 (Gray/Black)	Speed Sensor	195

If resistance for each circuit is as specified, go to next step. If resistance is not as specified, repair harness as necessary and go to PINPOINT TEST A , step 2).

Actuator Electrical Check

Using ohmmeter, check and record resistance between circuits No. 495 (Tan wire) and No. 496 (Orange wire). See Figure. Check resistance between circuits No. 497 (White wire) and No. 498 (Pink wire). If resistance is 43-70 ohms, replace VAPS module and go to PINPOINT TEST A , step 2). If resistance is greater than 70 ohms or less than 43 ohms, repair harness and go to PINPOINT TEST A , step 2).

VAPS Harness & Connector Check

Ensure all doors and hood are closed. Turn ignition off. Connect ohmmeter positive lead to circuit No. 57 (Black wire). See Figure. Ground ohmmeter negative lead. Check resistance. If resistance is less than 15 ohms, go to next step. If resistance is greater than 15 ohms, repair harness and go to PINPOINT TEST A , step 1).

VAPS Harness & Connector Check

Ensure ignition is off. Connect voltmeter positive lead to circuit No. 298 (Purple/Orange wire) and negative lead to circuit No. 57 (Black wire). See Figure. Turn ignition on. Check voltage. If voltage is 12 volts or more, go to next step. If voltage is less than 12 volts, repair harness and connectors and go to PINPOINT TEST A , step 1).

Continuity Check

Using ohmmeter, check continuity of circuit No. 606 (White/Light Blue wire) between DLC and control module connector. See Figure and Figure. If continuity exists, replace VAPS module and go to PINPOINT TEST A , step 1). If circuit is open, repair harness and go to PINPOINT TEST A , step 1).

Data Link Connector (DLC) & VAPS Harness Check

Ensure doors and hood are closed. Turn ignition off. Disconnect VAPS harness from control module. Using ohmmeter, check resistance in circuit No. 606 (White/Light Blue wire) between DLC and VAPS control module connector. See Figure and Figure. Resistance should be 2 ohms or less.
Using voltmeter, check voltage in circuit No. 606 (White/Light Blue wire) between DLC and VAPS control module connector. Voltage should be less than 0.1 volt.

Using ohmmeter, check resistance in circuit No. 200 (Brown wire) between DLC and VAPS control module connector. Resistance should be 2 ohms or less.

Using voltmeter, check voltage in circuit No. 200 (Brown wire) between DLC and VAPS control module connector. Voltage should be less than 0.1 volt.

If voltage and resistance readings are as specified, go to PINPOINT TEST A , step 2). If resistance and voltage readings are not as specified, repair harness and go to PINPOINT TEST A , step 2).
