D: VAPS Module Harness Check

VAPS Module Harness Check

D1 VAPS Harness And Connectors Ground Check
- Turn ignition switch to OFF.
- Disconnect VAPS connector from power steering variable assist control and bracket.






- Connect positive lead of DVOM to Circuit 57 and negative lead to ground.
- Measure resistance.

Note: All fuel filler doors and hood must be closed for proper resistance readings.

Is resistance greater than 15 Ohms?
Yes
SERVICE harness.
Go to A1. A1- A3
No
Go to D2.

D2 VAPS Harness And Connectors Voltage Check
- Disconnect VAPS connector from power steering variable assist control and bracket.

Voltage Chart:

- Connect DVOM as shown.
- Turn ignition switch to RUN.

Are voltage readings near given values?
Yes
Go to D3.
No
SERVICE harness.
REPEAT D2.

D3 VAPS Harness And Connectors Resistance Check
- Turn ignition switch to OFF.
- Measure resistance between Circuit 57 (ground) and all other indicated circuits.






- Connect DVOM as shown.
- Measure resistance of each circuit, by moving positive lead.
