This vehicle uses the speed sensitive power steering (SSPS) system. The SSPS system is controlled by SSPS control module. The control module controls steering effort by controlling current supplied into magnetic coil that is equipped in steering gear according to vehicle speed variation.
When the ignition switch is turned to "ON", the SSPS control module will perform the self-test for about 1.5 seconds (max 3.0s) to diagnose malfunctions in SSPS circuit.
The ignition switch is ON.
| • | The SSPS control module detects a system voltage above 16 volts. |
| • | The SSPS control module detects a system voltage below 9 volts. |
| • | The SSPS warning light will illuminate. |
| • | Power steering assist will default to full power steering effort. |
| • | The SSPS will store a DTC 02 in memory. |
| • | Conditions for the fault are no longer present. |
| • | Using the scan tool |
Check for the following conditions if a history or intermittent DTC is indicated.
| • | A poor connection at the SSPS--Inspect the harness connectors for backed out terminals, improper mating, improperly formed or damaged terminals, and poor terminal to wire connections. |
| • | A damaged wiring harness--Inspect the wiring harness for damages. If the wiring harness appears to be in good condition, observe the display on the multimeter while moving the connectors and wiring harnesses related to the circuits. A change in the multimeter display during the test will indicate the location of the fault. |
Step | Action | Values | Yes | No |
|---|---|---|---|---|
1 | Did you perform the Diagnostic System Check - Vehicle? | — | Go to Step 2 | |
2 | Check for a poor connection at the SSPS control module and SSPS actuator. Did you find and correct the condition? | — | Go to Step 3 | — |
3 |
Is the voltage within the specified value? | 9-16 V | Go to Step 4 | Go to Step 5 |
4 | Check the voltage between the terminal 8 and 10 of control module wiring. Is the voltage within the specified value? | 9-16 V | Go to Step 9 | Go to Step 8 |
5 | Check the resistance between the terminal 43 of I/P fuse block and the terminal 8 of control module wiring connector. Is the resistance about 0 Ω? | 0 Ω | Go to Step 6 | Go to Step 8 |
6 | Check the fuse F15. Is the fuse blown? | — | Go to Step 10 | Go to Step 7 |
7 | Check the vehicle charging system including alternator. Refer to Charging System Test Is the charging system OK? | — | Go to Step 9 | |
8 | Replace or repair the damaged wiring. Is the repair complete? | — | System OK | — |
9 | Replace the SSPS control module. Is the repair complete? | — | System OK | — |
10 | Replace the fuse F15. Is the repair complete? | — | System OK | — |
