Pinpoint Test D: VAPS Module & Harness Check

  1. 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).

  2. VAPS Harness & Connector Check

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

    Circuit No. (Wire Color) Function Volts (DC)
    57 (Black) Ground Less Than .1
    150 (Dark Green/White) Speed Sensor (1)
    153 (Purple/Yellow) Actuator Less Than .1
    154 (Purple/Light Green) Actuator Less Than .1
    155 (Gray/Red) Actuator Less Than .1
    156 (Gray/Orange) Actuator Less Than .1
    200 (Brown) Diagnostic Less Than .1
    298 (Purple/Orange) Power Battery
    563 (Orange/Yellow) Speed Sensor (1)
    606 (White/Light Blue) Diagnostic Less Than .1
    Blank VIP Less Than .1
    (1) Specification is not available.

  3. VAPS Harness & Connector Test

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

    Circuit No. (Wire Color) Function Ohms
    200 (Brown) Diagnostic Open
    298 (Purple/Orange) Power 3.6
    150 (Dark Green/White) Speed Sensor 195
    153 (Purple/Yellow) Actuator Open
    154 (Purple/Light Green) Actuator Open
    155 (Gray/Red) Actuator Open
    156 (Gray/Orange) Actuator Open
    563 (Orange/Yellow) Speed Sensor 0.6
    606 (White/Light Blue) Diagnostic Open
    Blank VIP Open

  4. Actuator Electrical Check

    Using ohmmeter, measure resistance between circuits No. 155 (Gray/Red wire) and No. 156 (Gray/Orange wire). See Figure. Check resistance between circuits No. 153 (Purple/Yellow wire) and No. 154 (Purple/Light Green wire). If resistance is 43-70 ohms, replace VAPS module and go to PINPOINT TEST A , step 5). If resistance is greater than 70 ohms or less than 43 ohms, repair harness and go to PINPOINT TEST A , step 2).

  5. 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).

  6. 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).

  7. 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 no continuity exists, repair harness and go to PINPOINT TEST A, step 1).

  8. 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).
